Lava flows have blocked surface drainages, forming Navajo Lake which drains underground into two watersheds and was later further dammed by humans; another lava-dammed lake downstream from Navajo Lake is now a meadow and Blue Spring Valley also saw the development of lava dams. As a consequence, water on the Markagunt Plateau flows underground through sinkholes developed in limestone rocks, and the burial of surface drainages by highly permeable lava flows likely aided in their development; some sinkholes have formed in basalt and other karstic features are also found in the volcanic field. Many streams and ephemeral creeks head in springs or disappear into sinkholes.

The whole volcano did not deform during the eruption sequence. The eruption released about of sulfur dioxide, about half the quantity released by the 1980 eruption of Mount St. Helens, and was sufficient to cause a noticeable increase in atmospheric opacity. The Quebrada Tumbre was blocked, and its water chemistry noticeably altered, by the eruption. About of gypsum was deposited in the drainages around the volcano, forming a significant supply of sulfur in the region.

Natural surface, single-track trails will require some ongoing maintenance. However, if the trail is properly designed and constructed, maintenance should be limited to clearing downed trees, trimming back brush and clearing drainages. Depending on location, if the trail is properly designed, there should be no need for major rework such as grading or erosion control efforts. However, mountain trails which see both significant rainfall and human traffic may require "trail hardening" efforts in order to prevent further erosion.

With the Red Rock River included in its length, the river stretches another , for a total length of , one of the more significant drainages of south-western Montana. The name of the Beaverhead originates from Beaverhead Rock on the middle river. This rock formation was recognized by Sacajawea when the Lewis and Clark Expedition passed the area in 1805. There were also many beavers in the area at the time, but the name does not originate from the animal.

The major climatic characteristic of this region is the high concentration of rain during the rainy season (93% of total volume). When evaporation is analyzed, the region presents an annual deficit of 176 mm. Despite these particular variations, the regional climate is classified as tropical, with a rainy summer and dry winter. During dry periods, the above ground water sources can become very scarce although underground drainages are capable of keeping the discharge in Velhas River.

This species is found in the Kizilirmak and Yeşilırmak drainages in northern Anatolia, Turkey. It lives in waters which vary from those with a moderately fast flow to almost still waters and prefers muddy or gravel substrates, It remains abundant and widespread within the two drainage systems in which it occurs but it is suspected that a number f populations may have declined or been made locally extinct by the increasing construction of small hydro- electric dams.

Triplophysa stenura is a species of ray-finned fish in the genus Triplophysa. It lives in swift-flowing streams and is known from the Upper Yangtze, Upper Mekong, Upper Salween and Upper Brahmaputra river drainages in China and Vietnam. Whether this apparently widespread species really is one species needs to be studied. It grows to SL. A study from the Upper Brahmaputra found Triplophysa stenura to be the most prevalent prey species for Oxygymnocypris stewartii, a large predatory cyprinid.

By 1850, California had become part of the United States. The first American settlers moved into the Sonoma Valley and began farming fertile valleys and making modifications to the Sonoma Creek drainages. By the late 1800s, valley ditches were common and connections had been created between all the major isolated tributaries and Sonoma Creek. More mountainous areas of the watershed were generally settled by "gentlemen farmers" who tended business in town and ranched on their properties in mountains.

Desert riparian is a North American desert vegetation type (or biome) occurring in the bottoms of canyons and drainages that have water at or near the surface most of the year.Pam MacKay, Mojave Desert Wildflowers, 2nd Ed., p. 20-21 It is contrasted with the desert dry wash vegetation type in which water at or near the surface is lacking most of the year.

Little Lake Creek Wilderness - The Little Lake Creek Wilderness is on the western edge of the pineywoods of East Texas about five miles (8 km) north of the City of Montgomery. It was designated wilderness in 1984 under the Texas Wilderness Act. The area derives its name from the perennial creek of the same name that flows south through the center. The wilderness area is bisected by three major creek drainages: Little Lake Creek, Pole Creek, and Sand Branch.

Those drainages create a rich ecological mosaic. Loblolly and shortleaf pines dominate ridgetops that are separated by a wide variety of hardwoods along the creek channels. The area is bounded by private land to the south, FM 149 to the east, FS 211 and an abandoned pipeline right-of-way to the west, and FS 231 to the north. Big Creek Scenic Area - The Big Creek Scenic Area was established in 1962 as a special interest area.

Epioblasma flexuosa, the arcuate pearly mussel or leafshell, was a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. This species was endemic to the United States, where it was found in the major drainages of the Ohio River, including the Cumberland, Tennessee, and Wabash Rivers. Its natural habitat was flowing water. Like most other members of this sensitive genus, it became extinct early after industrialization due to habitat loss and pollution.

Planiloricaria cryptodon is the only species of the monotypic genus Planiloricaria, a genus of the family Loricariidae of catfish (order Siluriformes). This species is native to Bolivia, Brazil and Peru where it occurs in the upper Amazon basin, including the Ucayali, Purus, and Mamoré River drainages. P. cryptodon inhabits sandy substrates in the main streams of large rivers. P. cryptodon reaches a length of SL. Although reproductive habits are unknown, this species is probably a lip brooder.

The branches, each about long, flow south, closely parallel to each other, and join at the Stillwater Lake reservoir in Union Dale. The combined river flows southwest past Forest City, Carbondale, Mayfield, Jermyn, Archbald, Jessup, Blakely, Olyphant, Dickson City, Throop, Scranton, Taylor, Moosic, Old Forge, and Duryea. It joins the Susquehanna River at the northern boundary of Pittston about west-southwest of Scranton. By the mid-20th century, the river was severely polluted from mine drainages in its watershed.

White-eye bream (Ballerus sapa) is a fish species of the family Cyprinidae. It is widespread in many large rivers in Europe and Asia in drainages of the Black Sea, Caspian Sea, and Aral Sea. It was introduced to several rivers in northern Russia, the Rhine (in 1995), and the Vistula drainage system where it is invasive, coming from the Black Sea basin through the Dnieper–Bug Canal. Freshwater fish are up to 35 cm long.

The distribution of redside dace is mainly limited to Southern Ontario, the Two Tree River on the St. Joseph Island being the only exception. Most populations have been identified in the streams draining into the western part of Lake Ontario, from the Pringle Creek near Oshawa to the Spencer Creek near Hamilton, Ontario. Smaller populations exist in the drainages of Lake Simcoe (Holland River system), Lake Erie (Irvine Creek), Berczy Creek in Markham and Lake Huron (Saugeen River system).

The Little Missouri River flows northeasterly through the county's lower portion, on its way to discharge into Lake Sakakawea, east of the county's east boundary line. The county terrain consists of semi-arid rolling hills, carved by river valleys and drainages. The area is partially devoted to agriculture.McKenzie County ND Google Maps (accessed February 26, 2019) The terrain slopes to the east and north, with its highest point on its south boundary line, at 2,684' (818m) ASL.

Montgomery County lies on the north line of Tennessee; its north border abuts the state of Kentucky. The hilly terrain is marked by drainages and largely covered with trees. The Cumberland River meanders westward through the lower central part of the county.Montgomery County TN (Google Maps, accessed 27 August 2020) The highest point on the county terrain (806 feet/246 meters ASL) is a small hill 3.7 miles (5.9 km) ENE from Slayden in Dickson County.

Etheostoma rufilineatum, the redline darter, is a species of darter endemic to the southeastern United States. This fish, like most other darter species, tends to inhabit clear, rocky riffles of streams, creeks, and small rivers. Both currently and historically, this fish is known from only the Tennessee and Cumberland River drainages in Tennessee, Virginia, Kentucky, Alabama, North Carolina, Georgia, and Mississippi. The average length for this fish is 6.9 cm, with a maximum recorded length of 8.4 cm.

Maidu ,Laurie Bauer, 2007, The Linguistics Student's Handbook, Edinburgh also Northeastern Maidu or Mountain Maidu, is an extinct Maiduan language spoken by Maidu peoples traditionally in the mountains east and south of Lassen Peak in the American River and Feather River river drainages. These river regions include such valleys in the northern Sierra Nevada mountains of California as: Indian Valley, American Valley, Butte Valley, and Big Meadows. Maidu may also refer to the related Konkow and Nisenan languages.

The whitetail shiner (Cyprinella galactura) is a freshwater fish in the family Cyprinidae. It inhabits the Tennessee and Cumberland river drainages of Alabama, Mississippi, Georgia, North Carolina, Tennessee, Virginia, and Kentucky, Atlantic slope headwaters (upper Savannah and Santee river systems, North Carolina, South Carolina, and Georgia), the upper New River drainage in West Virginia and Virginia, and the Ozark Plateau and Ouachita Mountains portions of the White and St. Francis river systems in Missouri and Arkansas.

Elk County consists of low rolling hills, carved by frequent drainages and heavily wooded. According to the United States Census Bureau, the county has a total area of , of which is land and (0.6%) is water. Elk has a warm-summer humid continental climate (Dfb) and average monthly temperatures in Ridgway range from 23.2 °F in January to 67.4 °F in July, while in Saint Marys they range from 22.6 °F in January to 66.8 °F in July.

The canyon is now known as Coon Canyon, and Coon Creek flowing out of it, is one of the major Oquirrh Mountain drainages. Coon Creek flows north and west through Magna to the Great Salt Lake. The Pleasant Green Cemetery located in the Oquirrh foothills, at about 3500 South, was established in 1883. In 1890, in response to a law requiring all children to receive free public education, the first school was built in the community.

The high-country Salmo-Priest Wilderness is a somewhat wishbone-shaped area atop two Selkirk Range ridges that intersect at Salmo Mountain. The eastern ridge is somewhat lower, more wooded, more rounded off, and therefore more accessible than the steep-sided, rocky-crested western ridge. Streams have cut deep drainages into both ridges, which flow into Idaho's Priest River on the east and Sullivan Creek and the Salmo River into the Pend Oreille River on the west.

The Savannah darter (Etheostoma fricksium) iis a species of freshwater ray- finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is endemic to the eastern United States, where it occurs in the Edisto, Combahee, Broad and Savannah River drainages in South Carolina and Georgia. It inhabits gravel riffles, gravel and sand runs of creeks and small rivers. This species can reach a length of .

The orangebelly darter (Etheostoma radiosum) is a species of freshwater ray- finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is endemic to the eastern United States, where it occurs in the Ouachita and Red River drainages in southwestern Arkansas and southeastern Oklahoma. It occurs in gravel and rubble riffles and runs of creeks and small to medium rivers. This species can reach a length of .

The Vinegar Hill-Indian Rock Scenic Area is a high-elevation scenic area in the northeast portion of the Malheur National Forest. It provides vistas of the North Fork John Day Wilderness, the Middle and North Fork drainages of the John Day River, and the peaks of the Strawberry Mountain Wilderness to the south. Many species of alpine wildflower found west of the Rocky Mountains grow in the area. Big game species and upland game birds are common.

Centennial Wash enters from the northwest as the river corkscrews south and west, around the Gila Bend Mountains. The Centennial Wash drainage is adjacent to the south-flowing Hassayampa River Drainage on the east; the next drainage east is the Agua Fria Drainage-(as shown on map). To the south as the Gila River makes its turns, arriving at the Painted Rock Reservoir, the Hassayampa and Centennial Wash drainages abut the Lower Gila-Painted Rock Reservoir Drainage.

Distribution map of Galaxias olidus G. olidus occupies a vast geographical range on both sides of the Great Dividing Range from southern Queensland, south through eastern New South Wales, across much of Victoria and further west to the Adelaide Hills in South Australia, thus being found both in the Murray-Darling basin and in eastern and southern coastal drainages. How much of their coastal distribution is due to natural river capture events (although much of it is) and how much may be due to migration is not clear, for many of the species complex members have the ability to "climb" natural migration barriers with modified pelvic fin structures. Within the Murray-Darling system, the mountain galaxias continues the trend of specialisation into upland and lowland habitats, with this species generally found in upland habitats, and the flathead galaxias found in lowland habitats, though G. olidus strays down to the upland/lowland transition zone in some rivers particularly in South Australia. In addition many other members of the species complex have ranges confined to the upper reaches of their respective drainages.

The Ventura River watershed encompasses consisting of steep mountains and foothills, with altitudes ranging from to sea level. Valley floors are home to communities and farms. Conditions in much of the watershed remain natural and undeveloped, with 57% of its land area in protected status. Most of the watershed's primary streams and drainages are unchannelized, though the natural hydrologic patterns have been modified by two dams (the Casitas and Matilija) and three levees (the Ventura River, Casitas Springs, and Live Oak).

Copionodontines occur exclusively in the Chapada Diamantina; though the plateau is drained by four river basins, so far, these fish are exclusively found in drainages associated with the Paraguaçu River. Copionodontines occupy the upper reaches of fast-flowing streams on rocky beds, often with tiny or no water flow in the dry season. Fish tend to concentrate on quiet, deep pools, though some individuals lodge in narrow rock crevices in fast-flowing sectors. Habitat preferences also vary according to species.

To the west of the Apalachicola River, nearly all drainages experienced significant swelling. Several homes in Pensacola Beach were flooded by the immense precipitation, while the roof of a restaurant collapsed under the weight of water collecting on top of it. On Santa Rosa Island, the sewage system overflowed into Pensacola Bay. A combination of above average tides and heavy rainfall caused the collapse of a section of sand along the Intracoastal Waterway, temporarily blocking barge traffic between Pensacola and Panama City.

Spruce Knob was originally in the bottom (syncline) of one of these folds, but over time cracks in the Pottsville Conglomerate in the higher elevations allowed it to erode quickly, and the softer layers of shale and limestone were quick to follow. This left Spruce Knob as the highest point in the landscape. Spruce Knob (Spruce Mountain) is the westernmost extent of this intense folding and faulting. To the west, the Allegheny Plateau is composed of more gently sloping hills and dendritic drainages.

Crystallaria is a genus of freshwater ray-finned fish which is classified in the subfamily Etheostomatinae, commonly known as the darters, part of the family Percidae which also includes the perches, ruffes and pikeperches. They are found in the Mississippi River basin from Ohio to Minnesota and in southern Mississippi, northern Louisiana, and southeastern Oklahoma, and on the Gulf Slope of Escambia, Mobile Bay, and the Pearl River drainages. They have now been extirpated from Ohio, Kentucky, Indiana, and Illinois.

The southern edge of the mountains are broken up by several isolated volcanic plugs and numerous drainages, several of which have been deeply incised into a bright orange mudstone. Besides the Poachie range, the wilderness also encompasses more than of the ephemeral Big Sandy and Santa Maria Rivers. To the west of the Big Sandy, the Artillery Mountains are dominated by the striking red Artillery Peak, a volcanic plug. Some lands in and around the wilderness are private and not federally administered.

Big Frog Mountain is a mountain located in southeastern Tennessee in the Big Frog Wilderness, within the Cherokee National Forest. At tall, there is no higher point west of Big Frog Mountain until the Big Bend in Texas or the Black Hills of South Dakota. It is located on the divide between the Tennessee and Coosa drainages. A network of trails allow hikers to explore the mountain, which gains its distinctive name by, according to some, looking somewhat like a frog in profile.

Artemisia suksdorfii is a North American species of sagebrush in the sunflower family. It is known by the common names coastal mugwort, coastal wormwood, and Suksdorf sagewort. It is native to coastal regions from British Columbia, Washington, Oregon, and northern California as far south as Sonoma County, with isolated populations on Santa Catalina Island in Los Angeles County.Calflora taxon report, University of California, Artemisia suksdorfii Piper coastal mugwort Artemisia suksdorfii grows in coastal drainages and other habitat near the ocean.

Four geographical variants include one in the Pearl River drainage, a second in the Pascagoula drainage, a third in the Mobile Bay drainage, and a fourth in the Escambia and Yellow River drainages. No deleterious parasitism was found, but a single ectoparasite (Placobdella sp.) (leech) was on turtles during spring. The most common intestinal parasite was an acanthocephalan (Neoechinorhynchu), but was found in less than 25% of adult population. One adult female possessed a fluke (Telorchis sp.) in its small intestine.

Devil's Slide is a name given to a steep, rocky coastal promontory located about midway between Montara and the Linda Mar District of Pacifica. The terrain is characterized by steep, eroded slopes with natural gradients ranging between 30 and 50%. There are small coastal valleys throughout along the major drainages within the Montara Mountain watershed. The soils in these valleys are deep and moderately well-drained and have developed along the low terraces and alluvial fans of the stream channels.

Badakshan is the largest and most studied of the known gold-bearing quartz veins systems in the region. Many of the main drainages for the regions were sampled for placer gold by means of panned concentrates performed in the field. Several mapped areas show alluvial deposits that were trenched, and samples for which panned concentrates were developed and the gold content noted. Russian C1 + C2 Reserves for both Veka Dur and other quartz veins of 38.7Koz at 4.8g/t based on trench sampling.

Lake Chouteau was a glacial lake formed during the late Pleistocene along the Teton River. After the Laurentide Ice Sheet retreated, water melting off the glacier accumulated between the Rocky Mountains and the ice sheet. The lake drained along the front of the ice sheet, eastward towards the Judith River and the Missouri River. The maximum advance of the Laurentide Ice Sheet blocked the drainages of north- and east-flowing rivers, forming glacial lakes along the margin of the ice.

Grasses, sedges, and sunflowers were also common. Extensive mesophytic forest communities, similar to modern lowland and bottomland forests, occurred along major river drainages, especially the Mississippi embayment, the Alabama-Coosa-Tallapoosa Basin, the Apalachicola-Chattahoochee-Flint Basin, and the Savannah River Basin. Humans arrived as five thousand years passed following the retreat of the glaciers, while deciduous forests expanded northward throughout the region. Pockets of boreal elements remained only at high elevations in the Appalachian Mountains and in a few other refuges.

Glyptothorax is a genus of catfishes order Siluriformes of the family Sisoridae. It is the most species-rich and widely distributed genus in the family with new species being discovered on a regular basis. These species are distributed in the Black Sea basin, northern Turkey, south and east to the Yangtze River drainage in China and south throughout Indo-China to Java, Indonesia. They are found in Asia Minor (in the Tigris and Euphrates River drainages) and southwards to Southeast Asia.

The Gila trout is native to tributaries of the Gila River in Arizona and New Mexico. The Gila trout is found historically in the Verde and Agua Fria drainages in Arizona. Natural fish barriers prevented Gila trout from entering the upper Tonto Creek drainage (AZ). Gila trout have persisted in five streams within the Gila National Forest, New Mexico, including: Iron, McKenna, and Spruce creeks in the Gila Wilderness Area, along with Main and South Diamond creeks in the Aldo Leopold Wilderness Area.

The Jackson National Fish Hatchery produces around 400,000 Snake River fine-spotted cutthroat trout annually to support fisheries in Idaho and Wyoming. The Leadville National Fish Hatchery produces 125,000–200,000 Snake River fine-spotted, greenback cutthroat and rainbow trout annually to support fishing in the Fryingpan and Arkansas River drainages and other Colorado waters. The Bozeman Fish Technology Center, formerly a cutthroat trout fish hatchery in Bozeman, Montana, plays a major role in the restoration of the greenback and westslope cutthroat trout subspecies.

The overflow channel was not always located at Adobe Valley, however; a more northerly spillway existed until faulting and volcanism shifted the overflow sill towards Adobe Valley. The northerly "Mount Hicks spillway" is presently higher than the Adobe Valley sill, and passes between the Bodie Hills and the Wassuk Range into Mud Spring Canyon, Rough Creek and eventually East Walker River.. This change in spillways is biologically important, as it allowed animals to use Lake Russell as a "transfer point" between different drainages.

In the 1990s, information and sightings were available from 39 localities in 10 different river drainages, along with the remote river systems of Borneo. Prior to the 1950s, Tomistoma occurred in freshwater ecosystems along the entire length of Sumatra east of the Barisan Mountains. The current distribution in eastern Sumatra has been reduced by 30-40% due to hunting, logging, fires, and agriculture.Bezuijen, M.R., Webb, G.J.W., Hartoyo, P., Samedi, Ramono, W.S., Manolis, S.C. (1998) The False Gharial (Tomistoma schlegelii) in Sumatra.

Stanišić was founded just at the edge of these two landmarks. The lower ground was populated by Serbs in 1763 and the upper by Germans in 1786 and by 1811 both villages were united in one. The surrounding area is a great Pannonian Plate without any hills, woods or rivers. In later periods small, tiny channels and drainages were built beside the village just to take off all the waters from the yards, meadows and gardens in the lower parts of the village.

Significant river drainages of the Metacomet Ridge include the Connecticut River and tributaries (Falls River, Deerfield River, Westfield River, Farmington River, Coginchaug River); and, in southern Connecticut, the Quinnipiac River. The Metacomet Ridge is surrounded by rural wooded, agricultural, and suburban landscapes, and is no more than from a number of urban hubs such as New Haven, Meriden, New Britain, Hartford, and Springfield. Small city centers abutting the ridge include Greenfield, Northampton, Amherst, Holyoke, West Hartford, Farmington, Wallingford, and Hamden.

Allegheny hardwood forests consist of black cherry, white ash (Fraxinus americana), and tulip poplar (Liriodendron tulipifera). Mixed-oak forests of northern red oak (Quercus rubra), white oak (Quercus alba), eastern black oak (Quercus velutina), and scarlet oak (Quercus coccinea) grow along major river drainages and on steep, drier slopes. Northern hardwood forests include sugar maple (Acer saccharum) and American beech. Also common are yellow birch (Betula alleghaniensis), eastern hemlock (Tsuga canadensis), red maple, black cherry, and eastern white pine (Pinus strobus).

Clark County lies on the east edge of Indiana; its eastern border abuts the northern border of the state of Kentucky (across the Ohio River). The terrain is low rolling hills, with the area either devoted to agriculture or urban development. The west part of the county is carved with drainages. Clark County IN (google maps - accessed 21 December 2019) The highest point on the terrain is a ridge WNW of Henryville near the border with Scott County, at 1,030' (314m) ASL.

Information Circular 7592. United States Department of the Interior, Bureau of Mines. Confirmation of concentration of the placer gold deposits in relatively recent times is indicated by the bones of mastodons and elephants that were dug out of the gravels. The distribution of the placer gold concentrations suggests that the common source of most of the placer gold in Confederate Gulch and White Creek was a series of quartz lodes on Miller Mountain on the divide between the two drainages.

In the 1820s the low rolling hills of Rush County were generously covered with trees, usually walnut and sugar maples. By 1879 Rush County was the state's largest producer of maple syrup. However, logging and clearing for agriculture have completely removed the trees, except for stands in drainages, and the available land is completely devoted to agriculture or urban development.Rush County, Indiana (Google Maps, accessed 6 August 2020) The Big Blue River drains the upper part of the county, flowing to the southwest.

Switzerland County lies at the SE tip of Indiana, with its southeastern border defined by the Ohio River; the state of Kentucky abuts on the opposite shore. Its rolling hills were originally completely wooded. Its more flat areas have been cleared for agricultural or urban use, but its many drainages are still wooded.Switzerland County IN (Google Maps, accessed 13 September 2020) Its highest elevation (981 feet/299 meters ASL) is a hill in its NW quadrant, 0.7 mile (1.1 km) west of Avonburg.

In low sun-angle photography additional scarps and splays can be observed. The erosion/sedimentation patterns and the path of drainages such as Canyon Creek may have been influenced by movement along the fault, and topographic ridges are offset. Finally ductile folding, vegetation and landform variations have also been recognized on the Meers fault. In some rock formations faulting has mainly led to warping, instead of brittle displacements and in several sites evidence of faulting appears to be concealed by floodplain sedimentation.

Part II (Ss. 7 & 8) of the Law specifies that the agency shall: #Ensure the efficient and effective maintenance and rehabilitation of all existing state roads and drainages or any other road or drainage as may be declared at any time, as a State road by the State Government. #Set guidelines for the working of concession contracts; enter into road concession contracts for the purpose of executing relevant projects. #Plan and manage the development and implementation of the road safety standards.

Epioblasma propinqua, the Tennessee riffleshell or nearby pearly mussel, was a species of freshwater mussel in the family Unionidae. It was endemic to the United States, where it was found in the drainages of the Cumberland River, Ohio River, and Tennessee River. Like most other members of its genus, it became extinct due to habitat loss in the form of dam construction, dredging, and pollution. This species was particularly sensitive to these effects, and appears to have declined greatly during early industrialization.

Rhadinoloricaria macromystax is the only species of the monotypic genus Rhadinoloricaria, a genus of the family Loricariidae of catfish (order Siluriformes). Rhadinoloricaria is part of the Pseudohemiodon group of the tribe Loricariini in the subfamily Loricariinae. Apistoloricaria and Crossoloricaria include fish that are very similar to Rhadinoloricaria, and it has been proposed that the former two genera be synonymized with the latter. This species is native to Ecuador and Peru where it occurs upper Amazon and Orinoco River basins, Essequibo, and Tocantins drainages.

The Bloody Creek structure lies within the Southern Upland of southwestern Nova Scotia. The Southern Upland consists of poorly drained, gently-rolling, hilly topography that is characterized by glacially deranged drainages and extensive lakes and wetlands. A large granite batholith, which has intruded slate and greywacke, underlies the Southern Uplands. Within this region, bedrock is poorly exposed as the result of low relief; a widespread surficial blanket of glacial till; and numerous large depressions filled with either wetland peat or occupied by lakes.

Some areas, including streams in the Kisatchie National Forest, undergo increased sedimentation from nearby silviculture, road maintenance, and livestock grazing. Gravel mining may also cause increased sediment. Genetic analysis reveals the species has low genetic variability, which makes it more vulnerable to changes in its environment. Because it is restricted to only two river drainages in central Louisiana, and declined by over 80% during the last few decades, the International Union for Conservation of Nature has rated this mollusk as being "critically endangered".

The protected area is located in the southwestern area of the province of British Columbia, in the Cariboo region, on the southern edge of the Chilcotin Plateau. It encompasses most of the drainage area of Churn Creek, and its eastern boundary is the Fraser River. The southern portion of the park includes a large expanse of the western bank of the Fraser, including the lower parts of the drainages of Grinder and Lone Cabin creeks. It also includes several small lakes.

It heads in the high divide between the Kugruk and Agiapuk drainages, and flows eastward, cutting across the strike of the schists and limestones. At the mouth of the creek the bed rock consists of highly altered mica-schists. Henry Creek is tributary to the Kugruk River from the west. It heads in the high divide south of Kugruk Mountain, and flows eastward in a deep canyon cut in the upland and across the strike of the schist and limestone bed rock.

This Colombian-Venezuelan range extends to the coast, and is coastal along northern Venezuela, as it is an extension of the range from the Guianas, (western Guyana). The cocoa thrush's range covers the downstream eastern half of the Amazon Basin; in the northeast Basin, it is in Pará and Amapá state with the Guianas. In the southeast Basin, it is in the Tapajos River and Xingu River drainages; also two thirds of the adjacent river system, the lower Araguaia-Tocantins River drainage.

Birken Lake is the summit lake of Seton Portage's big twin, the Long Portage, aka Pemberton Pass, which separates the Birken and Seton drainages. In 1858, gold was discovered in British Columbia. Steamships started running on both Seton Lake and Anderson Lake, and Seton Portage became a transportation bottleneck, as prospectors would need to portage for between the lakes. In 1861, Carl Dozier constructed British Columbia's first railway here to transport passengers and freight across Seton Portage (then called Short Portage).

In Guizhou, he made the discovery of the true source of the West River. He also discovered the Mekong and Salween rivers were, in fact, separate drainages with completely separate watersheds.Needham, Volume 3, p. 524-525. Xu made the important realization that the Jinsha river network and not the Min or Yalong formed the true headwaters of the Yangtze River, correcting a mistake in Chinese geography as old as the "Tribute of Yu" compiled by Confucius in the Classic of History.

The river darter is a species native only to the United States and Canada. Within Canada, the river darter is native to southern regions including the Hudson Bay basin, Ontario, and Manitoba. Within the United States, the river darter is native to a band that starts northward in Canada and extends into Minnesota and North Dakota and continues to the Gulf drainages in Alabama and Texas. The river darter is the most common species of darter in the Mississippi River Channel.

The terrain of Jones County consists of semi-arid rolling hills, partially devoted to agriculture. The Bad River flows northeasterly through the northwest corner of the county, and the White River forms the county's southern boundary. The southern areas of the county are carved with gullies and drainages flowing to the White River.Jones County SD Google Maps (accessed 4 February 2019) The terrain generally slopes to the northeast, and its highest point is on the lower western boundary, at 2,444' (745m) ASL.

The area is part of the Central Appalachian Broadleaf Coniferous Forest-Meadow Province. Most of the vegetation is broadleaf. Yellow poplar, northern red oak, white oak, basswood, cucumber tree, white ash, eastern hemlock and red maple are found in colluvial drainages, toeslopes and along flood plains of small to medium-sized streams. White oak, northern red oak, and hickory dominate on the north and west, while chestnut oak, scarlet oak and yellow pine are found on the north and west.

Daily Independent Online The soil at Isuikwuato is loose and suffers from Erosion and this left some dangerous erosion sites in the area. They lack the needed government backing to build drainages around the area to guide the flow of water without further harming the already crying soil. Blessed with hills and highlands, the town will appreciate water infrastructures because water is an important but hard resource to get in Isuikwuato. Isuikwuato is also home to Abia State University Uturu.

The Purcell Wilderness Conservancy covers the central region of the southern half of the Purcell Range in the south east of the province, often referred to as the Kootenays. The nearest settlements are Argenta, to the west, and Invermere to the east. The park encompasses several large drainages in their entirety, and contains the headwaters of several other large streams and rivers. On the western side of the park, Hamill, Fry, and Carney Creeks flow into Kootenay Lake and the Kootenay River system.

A 2004 study supported three major, more or less geographically distinct, clades of Bedotia, one comprising species with distributions ranging from mid- to southeastern Madagascar (B. madagascariensis, B. geayi, and B. tricolor, plus four undescribed species), another including species restricted to eastern drainages north of the Masoala Peninsula (B. marojejy, plus four undescribed species), and a third comprising species with distributions extending from the Masoala Peninsula southward to the Ivoloina River (B. longianalis and B. masoala, plus three undescribed species).

The Monterrey platyfish is one of three Xiphophorus species that is restricted to the southern Rio Grande basin and threatened The various Xiphophorus species range from the southern Rio Grande basin in Mexico, through eastern drainages in the country (river basins draining into the Gulf of Mexico), to northern Guatemala, Belize and northern Honduras. Three species and their hybrids are common in the aquarium trade: the green swordtail (X. hellerii), the southern platyfish (X. maculatus) and the variable platyfish (X. variatus).

It is possible however that around 22,600 ± 130 years ago Lake Panamint was split into a northern basin sourced from local drainages and a southern one receiving water from Lake Searles. By 15,050 ± 80 years ago Lake Panamint began to recede as overflow from Searles ceased. By 14,925 radiocarbon years ago Lake Panamint was definitively receding. Presently, the Panamint Valley is considered to be part of physiographical region of the Sonoran Desert and contains two playas, South Panamint Playa and North Panamint Playa.

Lower Moses Coulee looking up canyon on the Waterville Plateau. Drainages of the plateau which existed prior to the glacial floods cut the truncated streambeds on the sides of the coulee. A precursor to glacial-flood-cut Moses Coulee existed prior to the glacial floods as a drainage basin with a number of side streams, draining the southern portion of the plateau. These streams had combined into a canyon that drained to the Columbia near the current mouth of Moses Coulee.

Tanner Butte is a peak in Hood River County, Oregon, on the edge of the Columbia River Gorge. Its elevation makes it the highest point in the western Gorge.

Hatfield Wilderness, a wilderness area within the Mount Hood National Forest, on the boundary of the Bull Run Watershed.

The lowest elevations of the Buckhorn Wilderness are found in the lower parts of the three principal drainages: at the Big Quilcene River, at the Dungeness River, and at Townsend Creek. The highest point in the wilderness is at the summit of Mount Fricaba, which lies on the western boundary of the wilderness area, shared by Olympic National Park. The tallest peak entirely within the wilderness is Buckhorn Mountain at . A notable historical site in the Buckhorn Wilderness is the Tubal Cain mine.

Alligator Gar (Atractosteus spatula) The largest member of the gar family, the alligator gar (Atractosteus spatula), can measure up to 10 feet long and weigh over 300 pounds. Its body and snout are wide and stocky, and it was named "alligator gar" because locals often mistook it for an alligator. The species can be found in Texas, Oklahoma, Louisiana, the Mississippi River, Ohio, the Missouri river, and the southern drainages into Mexico. Its habitat consists of lakes and bays with slow currents.

The extent of land basin drained by a stream is termed its drainage basin (also known in North America as the watershed and, in British English, as a catchment). A basin may also be composed of smaller basins. For instance, the Continental Divide in North America divides the mainly easterly-draining Atlantic Ocean and Arctic Ocean basins from the largely westerly-flowing Pacific Ocean basin. The Atlantic Ocean basin, however, may be further subdivided into the Atlantic Ocean and Gulf of Mexico drainages.

Three major drainages of the Colorado River enter in the Parker Valley region. The Bill Williams River and Bouse Wash have confluences with the Colorado in the northern valley area, from watersheds on the east. Tyson Wash crosses the La Posa Plain and enters downstream, with its watershed east of the river in the Colorado River Indian Reservation. In California, the Vidal Valley and the Whipple Mountains border the Parker Valley on the northwest, and the Palo Verde Valley on the southwest.

Charleston, West Virginia The diamond darter was described from specimens collected from the drainages of the Cumberland, Elk, Green, and Muskingum Rivers, which are all part of the Ohio River basin, from 1980 to 2005. Because of river alterations, and problems with water quality, the diamond darter's range has become greatly diminished. As of 2008, the fish is only known to still live in the Elk River, West Virginia. The effect of the 2014 Elk River chemical spill to the diamond darter is still unknown.

The highland darter (Etheostoma teddyroosevelt) is a fish in the family Percidae and is found in the Arkansas and upper White river drainages on the Ozark Plateau of Missouri, Arkansas, extreme southeastern Kansas, and northeastern Oklahoma. It was named after the 26th president of the United States Theodore Roosevelt and for his enduring legacy in environmental conservation and stewardship, including the designation of vast areas as national forests, wildlife refuges, national monuments, and national parks, and his efforts to forge the American Museum of Natural History.

The species occurs in North America from the San Antonio Bay drainage in Texas east to Mississippi, Alabama and Indiana, and north to Minnesota. It was formerly present in the Lake Michigan drainage area. In Louisiana, the bluntnose darter is one of the most widely distributed darters and is found in all river drainages, but it is absent in the southernmost estuarine environments. The species is found in swamps, floodplain lakes, sloughs, and low-gradient creeks, often over substrates of mud, clay or detritus.

The dwarf flathead gudgeon is found in estuaries and freshwater rivers from Baffle Creek in central Queensland through New South Wales and eastern Victoria to Wilsons Promontory. Inland the range extends westward along the Murray River into South Australia. In the southern parts of its range, it is more restricted to estuarine habitats, and is found further upstream in more northerly river drainages. The dwarf flathead gudgeon is commonly found alongside its larger relative, and often near some form of cover such as submerged vegetation or rocks.

Lewis and Clark Pass is a mountain pass on the continental divide in Montana, United States, at an elevation of above sea level. The pass lies at the head of the drainages of the west-flowing Blackfoot River and the east-flowing Dearborn River, in the Helena National Forest in Lewis and Clark County. The Continental Divide Trail traverses north and south through the pass. In the early 19th century, the pass was a heavily-used pathway where native peoples crossed over the continental divide.

The Montenegro Fault is part of the Romeral Fault System, running through the western slope of the Central Ranges. The fault is located to the west of the city of Armenia. The fault crosscuts and deforms the Pleistocene volcanic and volcano-sedimentary deposits of the Quindío Fan (), which covers about . The Montenegro Fault forms outstanding fault scarps as much as in height, beheaded streams, hanging valleys, ponded alluvium, aligned and offset drainages, as well as soil and rock slides on the face of the scarps.

This siltation results in discoloration of rivers to a dark red brown color and leads to fish kills. Erosion is also an issue in areas of modern farming, where the removal of native vegetation for the cultivation and harvesting of a single type of crop has left the soil unsupported. Many of these regions are near rivers and drainages. Loss of soil due to erosion removes useful farmland, adds to sediment loads, and can help transport anthropogenic fertilizers into the river system, which leads to eutrophication.

Elseya albagula, commonly known as the white-throated snapping turtle, is one of the largest species of chelid turtles in the world, growing to about carapace length. The species is endemic to south-eastern Queensland, Australia, in the Burnett, Mary, and Fitzroy River drainages. This species is entirely aquatic, rarely coming ashore and is chiefly herbivorous, feeding on the fruits and buds of riparian vegetation, algae, and large aquatic plants. First proposed as a species by John Goode in the 1960s,Goode J. 1967.

The area is part of the Ridge and Valley Subsection of the Northern Ridge and Valley Ecosystem Section, with rock types dominated by sandstone in the upper slopes and ridge tops, and shale and limestone in the bedrock on lower slopes. With a ridgetop extending along the area and many sideslope drainages, Patterson Mountain dominates the area. From a high elevation of 2260 feet at a crest of the mountain, the elevation dips to 1133 feet at the beginning of the Elmore Trail on Forest Rod 184.

While mule deer, elk and moose are the only large mammals inhabiting Portneuf WMA, a number of small mammals also call the area home. Beaver reside in some creek drainages, along with porcupine and mink. Coyotes, raccoons, yellow-bellied marmots, cottontail rabbits and the occasional bobcat and mountain lion also roam WMA lands. Golden eagles, Northern harriers, red-tailed hawks and great horned owls are commonly seen on Portneuf WMA. Swainson’s and rough-legged hawks are early spring visitors, passing through on their migration flights north.

In the Balkan Peninsula, Potamon fluviatile is known to occur in Croatia, Montenegro, North Macedonia, Albania and Greece. There are four species of Potamon in the Balkans, and P. fluviatile is replaced by Potamon ibericum in northeastern Greece. In mainland Greece, P. fluviatile is found in the drainages of the Axios, Thyamis, Aheron and Arachthos, Pineiós, Piros-Tethreas, Pamisos and Evrotas rivers. In the Ionian Islands, P. fluviatile is known to occur at only one site on Corfu, as well as on Kefalonia, Lefkada and Zakynthos.

Broadleaf evergreen and pine forests occupied an extent similar to their current one, primarily in the Atlantic Coastal Plain. Mesophytic and bottomland forest communities continued to occupy the major river drainages of the region. Although the major modern community types were flourishing in the Southeast by 10,000 years BP, and the climate was similar to that today, the understory flora had not yet come to resemble modern herbaceous floras. Mixed hardwood forests dominated the majority of the upper Coastal Plains, Piedmont, and lower mountain regions.

Large drainages into the oceans the world over can be seen to have continued over land which was once exposed, whether due to tectonic subsidence, sea level rise, or other factors. Bathymetric imagery is available for much of the United States' western coast, and in particular the ocean floor just offshore of rivers in the Pacific Northwest exhibit such underwater features. In certain locations there are still knickpoints preserved in these drowned river channels and valleys. A study conducted within the Mediterranean basin focused on such features.

Haskell Pass, elevation 4300 feet, is a historically significant but now little-used mountain pass in northwestern Montana, between the Flathead and Kootenai River drainages. From 1892 to 1904 it was traversed by the original main line of the Great Northern Railway from Kalispell to Libby. This route was abandoned in favor of a longer but flatter route via the Stillwater, Tobacco, and Kootenai Rivers. On the west side of the pass, much of the gravel Pleasant Valley Road lies atop the old roadbed.

Once the catheter is removed, contrast is injected into the cyst cavity to determine the remaining size and to monitor progress. The success rate is around 50%, and the unsuccessful drainages are mostly caused by large ductal leaks or blockage of the main pancreatic duct. This method is not recommended when patients cannot manage a catheter at home or with patients whose cysts contain bloody or solid material. Surgical drainage of a pseudocyst involves creating a pathway between the pseudocyst cavity and the stomach or small bowel.

The area is part of the Central Appalachian Broadleaf Coniferous Forest-Meadow Province. Yellow poplar, northern red oak, white oak, basswood, cucumber tree, white ash, eastern hemlock and red maple are found in colluvial drainages, toeslopes and along flood plains of small to medium-sized streams. White oak, northern red oak, and hickory dominate on the north and west, while chestnut oak, scarlet oak and yellow pine are found on ridgetops and exposed sites. Wildlife populations are supported by five artificial waterholes created by blasting into rock.

It was introduced into the Firehole River above and below Firehole Falls, the Madison River and the Gibbon River below Gibbon Falls in 1890. Brown trout also occur in the Yellowstone River below Knowles Falls, the Gardner River below Osprey Falls, in Middle Creek, a tributary of the Shoshone River and the Gallatin River. These populations resulted from upstream migrations by fish stocked in Wyoming and Montana. Brown Trout do not exist in the Bechler River or Fall River drainages in the southwest corner of the park.

Microsurgery has been used to treat several pathologic conditions leading to infertility such as tubal obstructions, vas deferens obstructions and varicocele which is one of the most frequent cause of male infertility. Microsurgical drainages by placing micro vascular bypasses between spermatic and inferior epigastric veins as proposed by Flati et al. have been successfully performed in treating male infertility due to varicocele. Microsurgical treatment has been shown to significantly improve fertility rate also in patients with recurrent varicocele who had previously undergone non microsurgical treatments.

Pareiorhina brachyrhyncha is a species of armored catfish endemic to Brazil where it is known from stony piedmont tributaries of the left bank of Rio Paraíba do Sul, in the State of São Paulo, southeastern Brazil. These streams belong to the Ribeirão Grande (also known as Teteqüera), Guameral, and Piagüi sub-drainages. They drain the southeastern slope of Serra da Mantiqueira, a major mountain range that separates the Paraíba do Sul from the upper Paraná River basin. This species grows to a length of SL.

In the Chalcolithic period (3800–2300 BCE) settlement shifted to the site of Erimi- Pamboules near the village of Erimi. Erimi-Pamboules was occupied from the conclusion of the Ceramic Neolithic through the Chalcolithic period (3400–2800 BCE). Occupation in the Early Cypriot period (circa 2300–1900 BCE) is uninterrupted from the preceding Chalcolithic period, with occupation continuing along the Kouris River Valley and the drainages to the west. Sotira-Kaminoudhia, located to the northwest of Sotira-Teppes, on the lower slope of the hill, was settled.

Twenty-seven bulldozers were put into service, but they had severe difficulties moving in the mud near the dams, so dykes had to be constructed with shovels. A proposal by some US military to blow up the dams with missiles from a helicopter was rejected. The work was not restricted to the lake; drainages from other parts of the Seven Lakes were also dammed to minimize the flow into Riñihue Lake. These dams were removed later, with the exception of Calafquén Lake, which still retains its dam.

This species has disappeared from an estimated 70% of its range, and is now only found in about 256 streams or drainages in 28 counties of California. However, the species is still common along the coast, and most of their population declines are in the Sierra Nevada and Southern California. The California red-legged frog is an important food source for the endangered San Francisco garter snake in San Mateo County. Breeding occurs from November to March, or sometimes earlier toward the southern limits of its range.

Paretroplus polyactis is a vulnerable species of cichlid found widely in fresh and brackish water in coastal regions and associated river basins in eastern Madagascar.Sparks, J. S. (2008). Phylogeny of the Cichlid Subfamily Etroplinae and Taxonomic Revision of the Malagasy Cichlid Genus Paretroplus (Teleostei: Cichlidae). Bulletin of the American Museum of Natural History Number 314 :1-151 It is the only Paretroplus found in the southern half of Madagascar, and one of only two found in eastern drainages (the other is the far more restricted P. loisellei).

N. munitus is a diminutive catfish with a disjunct distribution across the southeastern United States. It is historically known from the Pearl River drainage and the Upper Tombigbee River drainage in Mississippi and Louisiana, and the Alabama River and Cahaba River drainages in Alabama. However, it has been extirpated from the main channel of the Tombigbee and Alabama Rivers, and is currently limited to the Coastal Plain rivers. The species lives exclusively in medium to large rivers free of sedimentation and over gravel shoals.

Pyramid Lake, Nevada. FDR on the taste of Nevada trout. The Lahontan cutthroat is native to the drainages of the Truckee River, Humboldt River, Carson River, Walker River, Quinn River and several smaller rivers in the Great Basin of North America. These were tributaries of ancient Lake Lahontan during the ice ages until the lake shrank to remnants such as Pyramid Lake and Walker Lake about 7,000 years ago, although Lake Tahoe--from which the Truckee flows to Pyramid Lake--is still a large mountain lake.

The county terrain consists of rolling hills, heavily wooded through its center section, dotted with lakes and ponds, and carved with drainages and gullies. The available area is devoted to agriculture.Otter Tail County MN Google Maps (accessed 26 April 2019) The county terrain slopes to the west and south. The highest point on the county terrain is attributed to two different points: Inspiration Peak, at 1,750' (533m); or an unnamed rise located 1.3 miles (2.1 km) WNW of Perch Lake, at 1,790' (546m) ASL.

Norman County lies on Minnesota's western border, abutting North Dakota across the Red River, which flows north along (and defines) the county's west line. The Wild Rice River flows west through the lower part of the county, discharging into the Red a little north of the county's southwest corner. The Marsh River rises in central Norman County and flows northwest into the Red near the county's northwest corner. The county terrain consists of low rolling hills, carved by drainages and lightly dotted with lakes and swampy areas.

Many Ancestral Pueblo relocated to the Rio Grande and the Little Colorado River drainages, where their descendants, the Hopi and the 19 Pueblos of New Mexico, now live. For approximately one hundred years the canyon area was uninhabited by humans. Paiute from the east and Cerbat from the west were the first humans to reestablish settlements in and around the Grand Canyon. The Paiute settled the plateaus north of the Colorado River and the Cerbat built their communities south of the river, on the Coconino Plateau.

The terrain is rugged, with steep slopes, and finger ridges dissected by small intermittent or permanent drainages. Streams in the northern portion of this area drain into the Sauk River, while the southern portion drains into the Skykomish River. Main features of this area include Skykomish Peak, Cady Creek Ridge and Cady Creek, as well as the Beckler River's tributary the Rapid River, the true source of the South Fork Skykomish River. The Pacific Crest National Scenic Trail traverses the southern portion of the wilderness.

The terrestrial ecoregion of Kalevansky is Scandinavian and Russian taiga (WWF ID#608), a region characterized by coniferous forests taiga. The freshwater ecoregion is classified as "Barents Sea Drainages" (FEOW ID#407), characterized by migratory species, low levels of endemism, and high numbers of species introduced by humans. FEOW notes that "The fish fauna is formed from immigrants of Atlantic and Siberian origins with only a weak assemblage of primary freshwater European species; thus, a "mixed" nature of the fish fauna is its main distinguishing feature".

The forkshell or Lewis pearly mussel, scientific name Epioblasma lewisii, was a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. This species was endemic to the drainages of the Ohio River, Cumberland River and the Tennessee River in the United States. Its natural habitat was shallow riffle-beds of large rivers. This habitat was largely destroyed by dam construction and canalization, and the last populations of this species died sometime during the middle of the 20th century.

There have been no sightings of Chinese paddlefish since 2003, and was reported as extinct in 2019. Past attempts of artificial propagation for restoration purposes have failed because of difficulties encountered in keeping captive fish alive. American paddlefish are native to the Mississippi River basin from New York to Montana and south to the Gulf of Mexico. They have been found in several Gulf Slope drainages in medium to large rivers with long, deep sluggish pools, as well as in backwater lakes and bayous.

The Sonoma Mountain AVA is an American Viticultural Area in Sonoma County, California, United States. It is centered on the Sonoma Mountain landform in the Sonoma Mountains. The appellation includes the town of Glen Ellen, California and is nearly surrounded by the Sonoma Valley AVA. The area is known for the diverse micro-climates that occur on exposed hillsides and shaded drainages, and as such is home to production for a wide range of varieties including Cabernet Sauvignon, Chardonnay, Pinot noir, Sauvignon blanc, Semillon, and Zinfandel.

The park contains an array of habitats, such as grassland, seasonal wetlands, stock ponds, perennial and ephemeral drainages, northern coastal scrublands and oak woodlands, with some low rock outcrops. The steep slopes of the plateau has protected the native wildlife species and from exposure to human development. The result is that several species that are considered threatened or endangered elsewhere in the state may be found here. These include the threatened California red-legged frog, the Alameda whipsnake, and the federally threatened California tiger salamander.

Backpackers cross a sheet of aufeis in the Anaktuvuk River Valley of Alaska Sheets of aufeis may block stream channels and cause their flood plains to widen as spring floodwaters are forced to flow around the ice. Research on aufeis has to a large extent been motivated by the variety of engineering problems the ice sheets can cause (e.g. blocking drainages and causing flooding of roads). Culverts and pipelines can actually help to block flow and lead to the development of more extensive aufeis.

In the very headwaters of the southern Amazon Basin, the upstream half of the river drainages, both in the southeast and southwest, the range overlaps with its sister Hydropsalis species, the scissor-tailed nightjar, which ranges into southeast Brazil through the caatinga, cerrado, and pantanal south into Argentina. The two species cover all of South America east of the Andes cordillera from central Argentina to the Caribbean coast; the exception is a small region centered southeast of the Amazon basin in the vicinity of Maranhão, Brazil.

The Glasgow sublobe blocked the Missouri River west of present-day Fort Peck, Montana, and created Lake Jordan and glacial lakes Circle and Lambert were formed to the east. The Yellowstone lobe spread south past Intake, Montana, and formed glacial Lake Glendive. At its maximum the ice may have blocked the Little Missouri River forming glacial Lake Mikkelson.A.D. Howard 1960 When the ice sheet began to retreat northward, the southwestern margin of abandonment its previous drainages and lakes formed in the depression along the ice margins.

The Columbia Basin Ecological Province is mainly a hilly upland that slopes up from north to south and that is dissected by numerous dendritic-pattern drainages. This ecological region is further subdivided into the northern ancient lake basin and the southern silty uplands. Soils in the area typically consist Bakeoven-Morrow complex, Lickskillet stony loam, Lickskillet-Rock outcrop, Morrow silt loam, and Onyx silt loam. The Columbia Basin Ecological Province merges with the Blue Mountain Ecological Province close to an elevation of around 3,500 feet (1,067 m).

During the dry season, small rafts made from moriche plalm leaf stems are used to search for caimans and turtles in seasonal lagoons. River Pumé use dugout canoes for fishing, pursuit of caimans, and turtles in the major drainages of the llanos, as well as for transportation. The Pumé manufacture a wide array of other traditional implements from string, woven materials, and wood. Manufactured clothing and cloth has been readily available to the Pumé since at least the 19th century, and probably much earlier.

The spoonhead sculpin can be found in Canada from southern Quebec to the Mackenzie River in the Northwest and Yukon Territories and in British Columbia. They are also found in northern Ohio, Montana, and in many of the Great Lakes like Lake Superior and Lake Erie. However, due to the large amount of pollution in Lake Erie the spoonhead population there is dwindling. The spoonhead is also a native Montana fish that can be found in the St. Mary and Waterton river drainages of Glacier National Park.

The area is part of the Central Appalachian Broadleaf Coniferous Forest-Meadow Province. Yellow poplar, northern red oak, white oak, basswood, cucumber tree, white ash, eastern hemlock and red maple are found in colluvial drainages, toeslopes and along flood plains of small to medium-sized streams. White oak, northern red oak, and hickory dominate on the north and west, while chestnut oak, scarlet oak and yellow pine are found on ridgetops and exposed sites. The area contains about 285 acres of potential old growth forest.

Poropuntius normani is a species of ray-finned fish in the genus Poropuntius which occurs in hill streams and near waterfalls in the upland reaches of river drainages in eastern Thailand, Western Cambodia, the Kong River in Laos and in north central Vietnam. It is common and although threatened by habitat destruction through deforestation it is assessed as Least Concern by the IUCN. It is sometimes eaten but is not a specific target of fisheries and is sometimes turns up in the aquarium trade.

The native range of the rainbow shiner consists of the Mobile Bay basin, including the Coosa, Cahaba, and Alabama River drainages. This species is known from, and was possibly introduced into the Black Warrior River system. These reports however, have been questioned recently based on the fact that this species is typically found in streams with limestone outcrops in the watershed. N. chrosomus is found along the southeast edge of the Black Warrior River system consisting of streams that have headwaters in limestone formations.

These side drainages are still visible today along the coulee walls as truncated streambeds, interspersed with gable-like highlands.Washington history link. The Okanogan lobe of the Cordilleran Glacier moved down the Okanogan River valley, covering 500 mi² of the Waterville Plateau and blocked the ancient route of the Columbia River, backing up water to create Glacial Lake Columbia and Lake Spokane. Initially water discharged from Lake Columbia by running up through the head of Grand Coulee and down through Foster Coulee to rejoin the Columbia River.

It prefers to live in clearer shallow water with a depth of 3–5 meters, and to surround itself in foliage. Its habitat ranges from the waters of Lake Michigan, the Lake Erie Basin, the Mississippi River System, and river drainages along the northern coast of the Gulf of Mexico from the Nueces River in Texas east to the lower Apalachicola River in Florida. It shares its habitat with the alligator gar, its main predator. These smaller gar live an average of 18 years.

Its dentition, with few teeth on the premaxillae, and its abdominal cover consisting of minute disjointed platelets resembles that of some representatives of the Loricaria group. Conversely, the papillose surface of the lips and sexually dimorphic features are more characteristic of the Rineloricaria group. This genus is distributed in the northwestern part of the South American subcontinent, in drainages of the Pacific and Atlantic Slopes of the Andes. Several species occur also in the upper Amazon River basin, upper Paraguay, and São Francisco River basins.

Brush Mountain East Wilderness is a U.S. wilderness area in the Eastern Divide Ranger District of the George Washington and Jefferson National Forests. It was designated as wilderness area in 2009 by Omnibus Public Land Management Act of 2009. Traversed by the Appalachian Trail, the wilderness is rugged and steep with contrasting habitats containing dry table mountain pine on the southwest ridges and sugar maples, white oaks, and hemlock in wetter drainages. Small tracts of old-growth forest support bird species dependent on mature, deciduous forests for breeding.

At the time of European encounter, the historic Lenape ( or ), a Native American people, also called Delaware Indians after their historic territory along the Delaware River, inhabited the mid-Atlantic coastal areas and inland along the Hudson and Delaware rivers. The Lenape claim that they came from the Mississippi River area around the year 1000. Their villages were along the Delaware River and along other river drainages that went into the Delaware or other rivers. Problems developed in the early 17th century when the Little Ice Age came to North America.

Roughlock Falls Nature Area Approximately 600 million years ago in the Precambrian, the area was covered by a sea. As waters subsided and land masses began to appear 60 to 30 million years ago (between the Paleocene and Oligocene epochs), drainages such as Spearfish Canyon formed as softer rock was eroded away. Today, a National Scenic Byway, U.S. Highway 14A, winds through the canyon. This area is truly a crossroads, and trees and plants from Rocky Mountains, eastern woodlands, northern forests, and the Great Plains areas can be found here.

Sliding across snow and ice is a rapid and efficient means of travel, and otters traveling over mountain passes, between drainages, or descending from mountain lakes often slide continuously for several hundred meters. Rear leg paddling enables continuous sliding where gravity is an insufficient or an opposing force. During winter, the North American river otters heavily use openings in the ice, and may excavate passages in beaver dams for accessing open water. Tracks in the snow North American river otters are highly mobile and have the capacity of traveling up to in one day.

The red-bellied piranha is distributed widely throughout the South American continent and is found in the Neotropical rivers of Argentina, Brazil, Bolivia, Colombia, Ecuador, Guyana, Paraguay, Peru, Uruguay, and Venezuela. They live in the warm freshwater drainages of several major rivers including the Amazon, Paraguay, Paraná and Essequibo, as well as numerous smaller systems. They can live in waters that are between , but are able to survive temperatures as low as for a period. They are mainly found in whitewater, but have also been recorded in blackwater and clearwater.

SFGate In Canada, North American river otters occupy all provinces and territories, except for Prince Edward Island. Historical records indicate North American river otters were once populous throughout most major drainages in the continental United States and Canada prior to European settlement. North America's largest North American river otter populations were found in areas with an abundance and diversity of aquatic habitats, such as coastal marshes, the Great Lakes region, and glaciated areas of New England. In addition, riverine habitats in interior regions supported smaller, but practical, otter populations.

On the north side of King Mountain, the ditch forks, carrying water to mines in both the Snake and Nome River drainages. The upper and lower sections of the ditch were built to be 8 feet wide at the bottom and 11 feet wide at the top, while the middle section was ten feet wide at the bottom and 14 feet at the top. It was designed to carry about 28,500 gallons per minute (Purington 1905:124). Construction on the ditch began in 1901, making it the first major water conduit on the Seward Peninsula.

The mud darter (Etheostoma asprigene) is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is endemic to the lowlands of the Mississippi River basin from Wisconsin and Minnesota south to Louisiana and East Texas. It is also found in the drainages of the Sabine and Neches Rivers of Texas and Louisiana. It can be found in slow-moving waters on riffles in rivers, as well as in creeks, swamps, lakes, and reservoirs.

In the rainy season, the Boteti discharges to the Makgadikgadi Pans, bringing that area alive with seasonal activity and high biological productivity.Hogan, C. Michael (2008) "Makgadikgadi" at Burnham, A. (editor) The Megalithic Portal In the dry season, the Boteti is particularly important to provide wildlife an area to congregate, since most seasonal ponds and drainages are devoid of water.Murphy, Alan; Armstrong, Kate; Firestone, Matthew D.; and Fitzpatrick, Mary (2007) Southern Africa: Join the Safari (4th edition) Lonely Planet, Footscray, Victoria, Australia, page 100, The Boteti flows southeastward Boteti River (n.d.). In Encyclopædia Britannica online.

The existence of a second smaller species related to the flathead gudgeon (Philypnodon grandiceps) had been strongly suspected since 1980. P. macrostomus was described in 2006 by Douglass Fielding Hoese and Sally Reader; the type specimen was collected in Glenreagh, New South Wales. Its species name derived from the Ancient Greek makro "large" and stoma "mouth". Genetic analysis of the species from the different river drainages across its range showed that populations from the Lang Lang River in Victoria had diverged much earlier and most likely represent a separate, as yet undescribed species.

The highest elevation in the park is the top of Bennett Mountain, . The entirety of Annadel was below the ocean floor as recently as twelve million years ago, around which time massive uplift and volcanic action formed the massif which comprises the park of today. Elevations in Annadel range from about above sea level. Slopes within Annadel commonly range from 15 to 30 percent, but it is not uncommon to encounter slopes up to 70 percent on steep slopes above drainages which are covered in douglas fir forest.

The Honda Fault extends through the Middle Magdalena Valley, close to the Magdalena River and the cities of Ambalema, Honda, and La Dorada. It offsets beds of the Miocene Honda Group, Pliocene Mesa Formation, and Quaternary sediment in alluvial terraces. The fault trace is characterised by continuous prominent scarps, aligned drainages, fault saddles, linear ridges and valleys, sag ponds, degraded scarps, and localized uplifts. The southern half of the fault has a very low to low slip rate (less than per year), while the northern half is low to medium at per year.

The Yazoo darter inhabits small, clear, mostly spring-fed streams with substrates that include clay, sand, gravel, or silt. Its range encompasses headwater streams in the Little Tallahatchie River's watershed, including the Tippah River and Cypress Creek, and the Yocona River watershed, including Otoucalofa Creek. The range includes Benton, Calhoun, Lafayette, Marshall, Tate, Tippah, Union, and Yalobusha counties and parts of Holly Springs National Forest. Based on mitochondrial DNA, it has been determined that there are two monophyletic clades, those in the Little Tallahatchie River and those in the Yocona River drainages.

When the Washburn party traveled through the Firehole River geyser basins in 1870, the river above Firehole Falls was barren of fish, the falls being a natural barrier to upstream migration. Unlike the Yellowstone River drainage, the upper Firehole was isolated from any connection to drainages on the Pacific slope. The absence of fish was overcome in 1889 when the first brook trout were introduced into the river above the falls. In 1890 brown trout were introduced into Nez Perce creek a Firehole tributary and in the 1920s, rainbow trout were introduced into the river.

The bantam sunfish is also known to occur, less commonly, in parts of extreme southwestern Illinois, the Bootheel of Missouri, McCurtain County in Oklahoma, and some Mississippi and Gulf Coast drainages of the State of Mississippi. Historically, isolated populations of the bantam sunfish occurred above the Fall Line in the Illinois River at Pekin, in backwater ponds and sloughs of the Wabash River drainage in White County, Illinois,Burr, B. M. 1977.

The Conservancy covers of coastal temperate rainforest, making it the largest such preserve in the world. It lies at the head of the Whidbey Reach of the Gardner Canal, and encompasses the drainages of the Kitlope, Kalitan, Gamsby, Tsaytis, Kapella, and Tezwa rivers. During the spring melt, these rivers are subject to heavy flooding and carry large amounts of debris. Much of the park is mountainous; south of the Kitlope River the granite domes and ridges are part of the Kitlope Range, a sub-range of the Kitimat Ranges.

The species is named from the Latin alba = white and gula = throat, which is a reference to the white blotching present on the throats of adult females in the species. The type locality for the species is the Burnett River in south-eastern Queensland, but it is also found in the Mary and Fitzroy River drainages to the north of the Burnett. Some have argued for each of these rivers to represent different species, but DNA, morphological, and morphometric analyses does not support this conclusion.Georges A, Adams M. 1996.

This fish is limited to a few creeks in northern California and southern Oregon, where its historical range was located in the Ash Creek and Turner Creek drainages in the basin of the Pit River, as well as the Goose Lake basin, which was once connected to the Pit River. It can currently be found in ten streams in this region. The stream habitat has substrates of sediment and cobble with large amounts of detritus in the water that the fish uses for cover. It also uses overhanging banks, large rocks, and vegetation for cover.

Water temperature, certain river characteristics such as prey items, variations of the species in different drainages, along with any known disease or parasite problems, is vital information to provide ideal habitat for the Alabama map turtle. Seasonal activity is determined mainly by water temperature. In one location, temperatures below 19 °C resulted in severe decline in feeding and activity, complete hibernation of the population did not occur, and no significant interspecific competition with other turtle species occurred. They are mainly in large coastal plains streams with large mollusks populations.

The southern coastal plain blackwater river floodplain forest is a forest system found in Alabama, Mississippi, Florida, and Georgia. These forests occur in the drainages of blackwater rivers and streams whose dark water is caused by high levels of tannins, particulates, and other materials accumulated as they drain through swamps and marshes. The water has little mineral sediment and few suspended clay particles. Typical trees of these forests include bald cypress (Taxodium distichum), water tupelo (Nyssa aquatica), swamp tupelo (Nyssa biflora), sweetbay (Magnolia virginiana), and Atlantic white cedar (Chamaecyparis thyoides).

The native range of the brown bullhead is in the Atlantic and Gulf Slope drainages. More specifically, it is found from Nova Scotia and New Brunswick to Mobile Bay, Alabama, and in the Great Lakes, Hudson Bay, and Mississippi River basins (from Quebec to Saskatchewan, south to Louisiana, and west to Texas). However, there is evidence that the brown bullhead was historically absent from the Gulf Coast west of the Apalachicola River and east of the Mississippi River. The species is also abundant in many regions as a result of stocking for food or sport.

Approximately ten thousand years ago there was a lake in the lowest elevation of Scotts Valley, and Paleo Indians lived near its shores. The lake receded to form a peat bog. Later, around 2000 BC, Ohlone people occupied areas along the remaining creeks, spring and seep areas, along with permanent and seasonal drainages, and on flat ridges and terraces.Environmental Impact Report for the Scotts Valley Redevelopment Area, Earth Metrics Incorporated, State of California Clearinghouse Report 7888 (1990) Therefore, areas along watercourses are considered likely locations for prehistoric cultural resources.

It joins the Muddy near Hanksville to form the Dirty Devil River, which flows southeastward out of the county's south border to discharge into the Colorado. Wayne County terrain varies from rough forestland on the west, to arid poor soil carved by drainages and rocky outcrops.Wayne County UT Google Maps (accessed 24 March 2019) The terrain slopes to the east and south; its highest area is near its NW corner, at 9,888' (3014m) ASL. The county has a total area of , of which is land and (0.2%) is water.

Looking into the Haleakalā crater Volcanic rocks protrude on a Maui beach The older, western volcano has been eroded considerably and is cut by numerous drainages, forming the peaks of the West Maui Mountains (in Hawaiian, Mauna Kahalawai). Puu Kukui is the highest of the peaks at . The larger, younger volcano to the east, Haleakalā, rises to more than above sea level, and measures from seafloor to summit. The eastern flanks of both volcanoes are cut by deeply incised valleys and steep-sided ravines that run downslope to the rocky, windswept shoreline.

The agencies in charge of the fisheries such as NOAA often lack the authority to act on existing threats. The new conceptualization of salmon habitat conservation posited that we must protect the most intact or valuable drainages first by working from the headwaters downstream to create a continuous corridor of protected habitat. Several of these sub-basin scale refuges would come together to protect an entire basin as a whole unit. This does not mean that all of the land will be owned by governments or conservation organizations.

The Bighorns provided important resources for ancestral indigenous people, including plants, migratory big game, rock shelters, tepee poles, and stone for tools. American Indian trails crisscrossed the range, while the canyons provided important winter shelters. Stone game blinds in the high country were used by pedestrian hunters to kill migratory big game animals with atlatl spear throwers or bows. The northern Bighorns and the Tongue River drainage were formerly a significant summer range for migratory bison that wintered in either the Bighorn Basin and the Powder River/Tongue River/Little Bighorn River drainages.

A key component of Lake Oroville is the hatchery that manages thriving populations of Chinook salmon and steelhead trout for the Feather River ecosystem. It has an interesting history of how it came to be. In the past there have been many attempts to artificially spawn salmon, shad, and trout in the Feather River and its drainages. Before the Oroville Dam was constructed, a majority of the fish hatcheries were located on the eastern side of the mountain range (about 100 miles northeast of the hatchery's current location).

The tropical gar (Atractosteus tropicus) is a species of fish from Central America, where it is found in the Pacific and Atlantic drainages from southern Mexico to Costa Rica. In Mexico it is known as pejelagarto, a contraction of the words "pez" (fish) and "lagarto" (alligator). This gar inhabits a wide range of fresh and brackish water habitats such as rivers, floodplains, lakes and pools, but avoids areas with a strong current. It reaches lengths of up to (although typically less than half that length) and a weight up to .

Although brook trout populations are under stress in their native range, they are considered an invasive species where they have been introduced outside their historic native range. In the northern Rocky Mountains, non-native brook trout are considered a significant contributor to the decline or extirpation of native cutthroat trout (Oncorhynchus clarki) in headwater streams. Non-native brook trout populations have been subject to eradication programs in efforts to preserve native species. In Yellowstone National Park, anglers may take an unlimited number of non-native brook trout in some drainages.

The Rio Uchusuma, a tributary of the Rio Mauri, originates on Casiri. A natural lake called Paucarani exists on the southeastern foot of Casiri, and the Quebrada Achuco valley is also located south of Casiri, accompanied by wetlands. On the other side, the southeastward-flowing Quebrada Mamuta lies to the north and northeast of the volcano, and to the northwest lie streams which flow through the lake Casiri and the lake Liñuma into the Rio Mauri. Volcanic activity has influenced the drainages through the formation of lava dams, altering watersheds.

The upper Blackwater River is called Blackwater Swamp. In this region of Virginia, many streams are called "swamps" but still function like streams in being long and linear, with water moving from one end to the other and laid out in a normal stream tributary network. In contrast, some of the region's wetlands are not streams, such as the bog-like pocosins found on the higher land between swamp-stream drainages. The Blackwater River was a transportation route in the 17th and 18th centuries, connecting the Chesapeake Bay settlements with the Albemarle Settlements.

The major part of the drainage flows in the latter direction. In the groups of hills between the other streams farther south such a feature is not so clearly to be made out, but it is true that the course taken by the drainage is predominantly toward the southeast. Toward the south the Kreyenhagen Hills become more worn, decline in elevation, and lose their relief. Prominent individual features are absent, and the foothill area is a rolling surface with low ridges and broad drainages sloping gradually toward and merging with the Kettleman Plain.

Rugged ridges in the west flatten into more open plateaus toward the east, with deep drainages on both sides. Its diverse forest changes from fir, cedar, western hemlock in the west to fir, pine, and larch in the east. This region provides habitat for deer, moose, mountain goats, mountain lions, bighorn sheep, the gray wolf, and is home to the largest population of lynx in the Lower 48. Snow falls between October and May, and the hard packed snow may block the high western-side trails sometimes until early August.

The quillback can commonly be found in the Hudson Bay, the Mississippi River basin, the Great Lakes, and drainages from the Delaware, Apalachicola, and Pearl rivers. They often comprise a large portion of the biomass of warmwater rivers, but they are very difficult to catch with traditional American angling methods.roughfish.com – Quillback carpsucker The quillback carpsucker is closely related to the highfin carpsucker and the river carpsucker. All three species are rarely caught by anglers due to their feeding habits, but they have been caught occasionally on worms, minnows, and artificial lures.

The current range for Notropis buchanani extends from the Mississippi River basin in the southern United States to Ontario in southern Canada. Populations have been reported in eastern Kansas, southeastern Nebraska, western Oklahoma and south to northern Alabama, Mississippi, and Louisiana. Populations of N. buchanani are also present in Gulf slope drainages in Texas,Hubbs, C., R. J. Edwards, and G. P. Garrett. 1991.

Blum Creek is a small glacial tributary of the Baker River in Washington state, in the United States. It is sourced from the Hagan Glacier and another unnamed glacier on the north face of Mount Blum, and flows approximately from there to its mouth at the Baker River. Hagan Glacier is located below Mount Blum and the creek is also fed by runoff from the Blum Lakes, a set of six lakes south of Bacon Peak. The creek joins the Baker River two drainages downstream of Sulphide Creek, another Baker River glacial tributary.

Clear Lake encompasses near Oregon Route 126, with a shallow northern region and a deeper southern zone, which reaches a maximum depth of . Other nearby lakes include Lost Lake, Lava Lake, and Fish Lake. Fish Lake is an ephemeral lake that dries up during the summer season, formed by the damming of local water drainages by a lava flow from Sand Mountain Volcanic Field about 3,850 years ago. Local topography has influenced eruptive activity in the past, directing lava flows downhill to the west and, with wind, directing tephra to the northeast.

The Stony Run Creek flows eastward through the upper east part of the county; the Florida Creek flows northeastward through the west end of the county, and the Lac qui Parle River also flows northeastward through the west central part of the county.

The Straight River rises in Freeborn County and flows northward through the central part of Steele County, continuing into Rice County on the north. The South Branch of the Middle Fork of the Zumbro River rises in Steele County and flows eastward into Dodge County. The county terrain consists of low rolling hills, etched with drainages, completely devoted to agriculture where possible.Steele County MN Google Maps (accessed 19 April 2019) The terrain slopes to the east and north, with its highest point near the midpoint of its south border, at 1,293' (394m) ASL.

Mount Pinatubo's volcanic activity has followed a cycle: centuries of repose terminated by a caldera-forming eruption with large pyroclastic flows; a post-eruption aftermath of rain-triggered lahars in surrounding drainages and dome-building that fills the caldera; and then another long quiescent period. During and after the eruptions, lahars descending along volcano channels may block tributaries from watersheds beyond Pinatubo, creating natural lakes. Geophysical evidence shows that there were at least two ancient lakes in the Mapanuepe River valley in the southwestern part of the volcano.

Balon's ruffe (Gymnocephalus baloni), also known as the Danube ruffe, s a species of freshwater ray-finned fish, a ruffe, from the family Percidae which is native to the drainages of the Danube from delta to Germany and the Dnieper from delta to Kiev and is expected to occur in the Dniester. It inhabits areas with sand or mud substrates. It is active at night and feeds on small invertebrates. This species can reach a length of SL. It is named after Polish-Canadian ichthyologist Eugene K. Balon (1930-2013).

The low, rolling hills of Marshall County are completely devoted to agriculture where possible (significant drainages are wooded).Marshall County IN (Google Maps, accessed 29 July 2020) The highest points on the terrain are three approximately equal swells (900'/274 meters ASL) along the south border line with Fulton County, 1.4 mile (2.2 km) NW of Richland Center.Marshall County High Point, Indiana (PeakBagger.com, accessed 29 July 2020) Marshall County contains three significant bodies of water: Lake of the Woods (NE portion); Lake Maxinkuckee (SW portion); and part of Koontz Lake (NW portion).

P. aurotaenia is found in the wet forests of the Choco region of Colombia, west of the Andes, in the Atrato and San Juan drainages. It lives on the ground of humid lowland and submontane forests, typically between altitudes of 60 and 520 meters, and is found in primary and secondary forest but not in degraded areas. As a vivarium subject, this frog is an active animal that will make use of vertical space. Kokoe dart frogs are highly social frogs that require high humidity, cool temperatures, and larger prey items than many dart frogs.

Nebraska does have brook stickleback populations, but they are generally found in small streams in the northern portion of the state. The fish have been found in Nebraska since the early part of the nineteen hundreds. River drainages that sustain brook stickleback populations are the Loup, Middle Platt, Niobrara, and smaller distributions in the Lower Platte, Missouri River tributaries, North Platte, and South Platte. Though the species appears to have an abundant distribution across North America, the Nature Conservancy has declared the species to be a S3 (vulnerable) level.

As with a large geographical distribution, this species also lives in a wide range of flowing water habitats. Waterways such as rivers, streams, floodwater streams and drainages, lakes, ponds, potholes, hot springs, sinkholes, and seasonal melt water or spring fed ponds are all viable brook stickleback territories. Though the species can thrive in these habitats, primary spawning, breeding, and rearing grounds are located in shallow (< 1.5m) near shore environments with high vegetation cover and low velocity water. The species has a wide elevation range with specimens identified from sea level to ~ 2,400m.

Plans were made to evacuate Valdivia, and many people left. To avoid the destruction of the city, several military units and hundreds of workers from ENDESA, CORFO, and MOP started an effort to control the lake. Twenty-seven bulldozers were put into service, but they had severe difficulties moving in the mud near the dams, so dykes had to be constructed with shovels from June onwards. The work was not restricted to the lake; drainages from other parts of the Seven Lakes were dammed to minimize additional flow into Riñihue Lake.

A clot, embedded deep in one of the inner veins of the legs, can be found via ultrasound before it dislodges and travels to the lungs, resulting in a potentially fatal pulmonary embolism. Ultrasounds is useful as a guide to performing biopsies to minimise damage to surrounding tissues and in drainages such as thoracentesis. Small, portable ultrasound devices now replace peritoneal lavage in trauma wards by non-invasively assessing for the presence of internal bleeding and any internal organ damage. Extensive internal bleeding or injury to the major organs may require surgery and repair.

The resulting inverted relief consists of ridges capped by basalt which are separated by adjacent drainages. In all about of sediment were removed from atop the youngest exposed formation in the park (the Late Cretaceous-aged Dakota Sandstone). The Virgin River carved out of sediment in about 1 million years.Corresponding to a rate of erosion of about 40 cm per 1,000 years (1.3 ft/1,000 yr) This is a very high rate of downcutting, about the same rate as occurred in Grand Canyon during its most rapid period of erosion.

Small areas of marble and limestone lenses form resistant outcrops that are prominent landscape features, often white to light gray in color. The Salinian block is made up of highly fractured, and deeply weathered meta-sediments, especially biotite schist and gneiss, intruded by plutonic (granitic) rocks such as quartz diorite and granodiorite. Both formations have been disrupted and tectonically slivered by motion on the San Andreas and associated fault systems. The Palo Colorado and Church Creek faults are prominent features influencing the linear northwest–southeast alignment of primary drainages.

The area is part of the Central Appalachian Broadleaf Coniferous Forest-Meadow Province. Yellow poplar, northern red oak, white oak, basswood, cucumber tree, white ash, eastern hemlock and red maple are found in colluvial drainages, toeslopes and along flood plains of small to medium-sized streams. White oak, northern red oak, and hickory dominate on the north and west, while chestnut oak, scarlet oak and yellow pine are found on ridgetops and exposed sites. There are a few stands of table mountain pine, a tree that has become uncommon because it requires fire to reproduce.

The basaltic Monaro Range separates the Snowy and Murrumbidgee drainages. Because the climate in the basaltic areas is too cold for really reliable cropping (Nimmitabel has had frosts in January), the main industry is raising sheep and beef cattle. The Monaro Highway is the main State highway which runs from Canberra south through the Monaro region. Other major roads in the region are the Snowy Mountains Highway which crosses the Monaro between Tumut and Bega, the Kosciuszko Road from Cooma to Jindabyne, and the Snowy River Way from Bombala to Jindabyne.

The southwest corner counties of North Dakota (Adams, Billings, Bowman, Golden Valley, Grant, Hettinger, Slope, and Stark) observe Mountain Time.

A female orangethroat darter The orangethroat darter is found in portions of the Mississippi River Basin and Lake Erie Basin of North America. It is found in the eastern and western tributaries of the Mississippi River Basin from southeastern Michigan and Ohio to eastern Wyoming. Its range extends south to Tennessee and west to the northern section of Texas; Gulf drainages (Trinity River to San Antonio River) of Texas, mostly on Edwards Plateau. Locally, the orangethroat darter is found regularly throughout middle Tennessee in appropriate, high quality habitats.

An avalanche snow bridge near a ski-resort in Vorarlberg. Avalanche control or avalanche defense activities reduce the hazard avalanches pose to human life, activity, and property."Mitigation and Land Use - Avalanches" , Colorado Geological Survey Avalanche control begins with a risk assessment conducted by surveying for potential avalanche terrain by identifying geographic features such as vegetation patterns, drainages, and seasonal snow distribution that are indicative of avalanches. From the identified avalanche risks, the hazard is assessed by identifying threatened human geographic features such as roads, ski-hills, and buildings.

Sekani or Tse’khene are a First Nations people of the Athabaskan-speaking ethnolinguistic group in the Northern Interior of British Columbia. Their territory includes the Finlay and Parsnip River drainages of the Rocky Mountain Trench. The neighbors of the Sekani are the Babine to the west, Dakelh to the south, Dunneza (Beaver) to the east, and Kaska and Tahltan, to the north, all Athabaskan peoples. In addition, due to the westward spread of the Plains Cree in recent centuries, their neighbors to the east now include Cree communities.

Lyman County is bordered on the north and east by the Missouri River, which flows southerly along its edge, and the western portion of its south line is also delineated by the White River, which then continued flowing eastward through the county's eastern area to discharge into the Missouri. Its upper central portion is drained by the Bad Horse Creek, which discharges into the Missouri near the midpoint of the county's north boundary. The county terrain consists of rolling hills, sloping to the river drainages. Its area is largely devoted to agriculture.

While the majority of this species is localized in northern Idaho, some instances of capture/sighting in western Montana and southeastern British Columbia have occurred. About 95% of observed populations in Idaho and Montana have been verified extant since 1987; the remainder may have [extirpated], but with a general lack of knowledge on the population trends of the Coeur d'Alene salamander. The majority of known specimens has been observed in the St. Joe and North Fork Clearwater River basins, but they also occur in the Selway, Kootenai, and Moyie drainages.

The Aztecs linked supernatural abilities especially to females, whose commitment to their young was associated with the role of wise women in their society. The raccoon also appears in Native American art across a wide geographic range. Petroglyphs with engraved raccoon tracks were found in Lewis Canyon, Texas; at the Crow Hollow petroglyph site in Grayson County, Kentucky; and in river drainages near Tularosa, New Mexico and San Francisco, California. A true-to-detail figurine made of quartz, the Ohio Mound Builders' Stone Pipe, was found near the Scioto River.

Other works included the Amsterdam Ship Canal, the foundation of the Spithead Forts, River Witham middle level, Thames Valley drainages, and sewerage in Brighton. When he died he was completing a large system of docks at Buenos Aires (a dredged channel long and a river frontage), where James Murray Dobson was the resident engineer. Harrison was a Lieutenant-Colonel in the Engineer and Railway Volunteer Staff Corps and served as President of the Institution of Civil Engineers between May 1892 and May 1893. He was buried at Highgate Cemetery.

The Kotosh Religious Tradition is a term used by archaeologists to refer to the ritual buildings that were constructed in the mountain drainages of the Andes between circa 3000 and c.1800 BCE, during the Andean preceramic, or Late Archaic period of Andean history.Moseley 2001. p. 109. Archaeologists have identified and excavated a number of these ritual centers; the first of these to be discovered was that at Kotosh, although since then further examples have been found at Shillacoto, Wairajirca, Huaricoto, La Galgada, Piruru,Burger 1992. p. 45.

They are restricted to suitable breeding and feeding grounds, making novel niche exploration rare, particularly in fast flowing drainages. Low mobility is hypothesized to have facilitated speciation in regions where multiple species appear to have historical sympatric distributions. Various life history traits like body size determine the niche range available to a particular species (Knouft, 2004)The biogeographic dispersal model has been proposed as the most likely explanation of diversification and speciation of the subgenera. It has also been postulated that speciation occurred following niche partitioning, in response to competition where distributions overlap.

Vimba vimba is distributed in fresh waters and in brackish estuaries of rivers draining to the Caspian Sea, Black Sea and Baltic Sea, and in the North Sea basin in the Elbe and Ems drainages. There are records from Armenia, Austria, Azerbaijan, Belarus, Bulgaria, Czech Republic, Estonia, Finland, France, Georgia, Germany, Hungary, Iran, Latvia, Lithuania, Moldova, the Netherlands, Poland, Romania, Russia, Serbia and Montenegro, Slovakia, Sweden, Switzerland, Turkey, and Ukraine. The vimba bream is a semi-anadromous fish, which migrates from brackish water to rivers for spawning. Permanently fresh-water populations exist as well.

The Carolina fantail darter (Etheostoma brevispinum) is a small species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is endemic to the eastern United States, where it occurs in the Santee and Savannah River drainages and Yadkin River system (downstream to and including the South Yadkin River and Bear Creek) of the Pee Dee River drainage in North Carolina, northern South Carolina and southern Virginia. This species can reach a length of .

While the population of the species is currently considered stable, they are of concern because of their small range, only found in a few major drainages in the state. Conservation efforts in South Carolina have a great impact upon the species as half of global distributions of the species occur in the state. Concerns for the species are similar to those of other fish in South Carolina: source pollution, deforestation, loss of riparian corridors, impoundment development, siltation resulting from poor land use practice, and poorly urban and suburban development.

The western ground snake (Sonora semiannulata) is a species of small, harmless colubrid snake. It is sometimes referred to as the variable ground snake as its patterning and coloration can vary widely, even within the same geographic region. It is native to the southwestern United States, in Texas, New Mexico, Arizona, Oklahoma, Colorado, Kansas, Missouri, Utah and California, as well as northern Mexico, in Sonora, Chihuahua, Coahuila, Nuevo León, and Durango. In Idaho, western ground snakes are found in the southwestern portion of the state, along the Snake River and surrounding drainages.

The forest is mainly composed of broadleaf trees with some yellow pine. Areas with a favorable environment for tree growth, such as colluvial drainages, toeslopes, and floodplains of smaller streams, contain yellow poplar, northern red oak, white oak, basswood, cucumber tree, white ash, eastern hemlock and red maple. A large fraction of the area, mainly on the west and north with a less favorable environment for tree growth, contains red oak, white oak, and hickory. Ridgetops, and east midslopes have a preponderance of chestnut oak, scarlet oak and yellow pine.

Lumber company-owned railroads extended into many of the local drainages including Grouse Creek, Gold Creek and Rapid Lightning Creek. Although the trees were never exhausted in the area, Humbird Lumber succumbed to the low timber prices of the Great Depression. "Stump ranches" were sold by Humbird to many families who slowly cleared much of the valley land of tree stumps. Farming and ranching became the third largest business in the area, behind lumber and railroads, prior to the "discovery" of Lake Pend Oreille as a sports fishery in the 1950s.

Cuvier's dwarf caiman is native to tropical northern and central South America. It is present in the drainages of the Orinoco River, the São Francisco River, and the Amazon River, and the upper reaches of the Paraná River and the Paraguay River. The countries in which it is found include Peru, Ecuador, Colombia, Venezuela, Guyana, Suriname, French Guiana, Brazil, Bolivia,Trinidad and Paraguay. The range of this species is rather larger than that of the sympatric smooth-fronted caiman, as it extends into Paraguay and includes a larger area of Brazil.

The Geology of the Raglan-Kawhia AreaGeology of the Raglan-Kawhia Area: Institute of Geological & Nuclear Sciences (N.Z.), Barry Clayton Waterhouse, P. J. White 1994 says, "The N-striking faults are evidenced by trends of the Tasman Sea coastline and probably by stream drainages such as that of the Opotoru River c 6 km E of Karioi summit." and "The base, consisting of interbedded conglomerate, sandstone, and locally siltstone, is strongly unconformable on Te Kuiti Group rocks south of Raglan at the Opotoru River estuary (R 14/751741)". Chert is found beside a tributary at Te Mata and pebbles have been found downstream.

Mapanuepe lake is located at the confluence of Marella and Mapanuepe Rivers as the two rivers merge to become the Santo Tomas River. The subsequent rains following the 1991 eruption of Mount Pinatubo produced lahar that dumped volcanic debris on the Marella River, one of the major drainages of the mountain, aggrading the river that eventually dammed the Mapanuepe River. The rising waters submerged the Mapanuepe Valley including the barangays of Aglao (lower), Buhawen and Pili of San Marcelino, Zambales. During the development of the lake, breaching and reforming of the debris dam occurred following each lahar episode.

The emerald darter is restricted to the Cumberland Plateau, including only the upper Cumberland River drainages in eastern Kentucky and northeastern Tennessee. Rivers where emerald darters can be found include the Red River, Jacks Creek, Indian Creek in Kentucky, and Clear Creek, Elk Creek, Poor Creek, and other small water systems. Though populations have fluctuated through the years, the emerald darter's geographic range has stayed the same, and in some areas they can even be found in abundance. Populations may have experienced declines in the past due to strip-mining and siltation in the gravel substrates in which it spawns.

The Kotosh Religious Tradition is a term used by archaeologists to refer to the ritual buildings that were constructed in the mountain drainages of the Andes between circa 3000 and c.1800 BCE, during the Andean preceramic.[1] Archaeologists have identified and excavated a number of these ritual centers; the first of these to be discovered was that at Kotosh, although since then further examples have been found at Shillacoto, Wairajirca, Huaricoto, La Galgada and Piruru.[2] These sites are all located in highland zones that are lower than the Puna, and yet there are considerable distances separating them.

In 2005, a company was hired by ALCOA to remove the chemicals from the riverbed near what is known as "Outfall One", one of the factory's water drainages just downriver from the powerhouse. The river bottom was removed and piped into machines where it was cleaned and deposited in a private landfill on ALCOA's property. ALCOA is also working on plans to prevent large chunks of ice from moving down this section of river. Early plans called for large cement barriers to be built in the town of Louisville, but those plans have met some opposition from local residents.

Lake Alamosa existed for about 3 million years, from the Pliocene to the middle Pleistocene. Rocks in the San Luis horst stretch across the entire Alamosa Basin and together with 4.8-3.7 million years old basaltic lava flows of the Taos Plateau blocked the basin from draining to the south. Tectonic uplift of the Jemez lineament, tectonic subsidence of the Lake Alamosa area and the emplacement of these lava flows may have obstructed former drainages, but evidence of prior southwards drainage has been found only recently. South of Lake Alamosa an even older lake, Lake Sunshine, occupied the Sunshine Valley during the Pliocene.

The Armenia Fault is part of the Romeral Fault System on the western slope of the Central Ranges of the Colombian Andes. The fault crosses the city of Armenia and displaces Pliocene to Pleistocene volcanic and volcano-sedimentary deposits of the Quindío Fan (), which covers about . The geometric and neotectonic features of the Montenegro and Armenia Faults are very similar. The fault forms well developed fault scarp as much as high, characterised by beheaded streams, ponded alluvium, aligned and offset drainages, soil and rock slides on the face of the scarp, and localised tilting of terrain.

The door to door solid waste collection was started from December 2007 and done in 8 wards out of 10 wards daily by Pushcarts with the help of women SHG group. The plastic garbage is collected separately and stock at this compost yard. The drainages are cleaned once in week by the sanitary workers. Power spraying is done using baytex and other mosquito killing minerals, once in 15 days in all town panchayat areas Solid waste collected from door to door is segregated in the compost yard and Biodegradable Solid waste is made into natural manure for agriculture purposes.

Lake Thompson was kidney shaped and covered a surface of (at first it was believed to have covered a surface of ). It developed in the westernmost Mojave Desert, covering much of the Antelope Valley to elevations of , with additional shorelines suggested at elevations of . Two islands existed in the water body, cliffs have been cut at some sites along its former shore and there are dunes as well. Stickleback fish may have entered the lake through Peninsular Ranges drainages and a number of different animals from snails over fish, amphibians, reptiles, birds to mammoths have been found in lake sediments.

The area is part of the Central Appalachian Broadleaf Coniferous Forest-Meadow Province. Yellow poplar, northern red oak, white oak, basswood, cucumber tree, white ash, eastern hemlock, white pine and red maple are found in colluvial drainages, toeslopes and along flood plains of small to medium-sized streams. White oak, northern red oak, and hickory dominate on the north and west, while chestnut oak, scarlet oak and yellow pine are found on ridgetops and exposed sites. There are a few stands of table mountain pine, a tree that has become uncommon because it requires fire to reproduce.

Its rostrum and cranium are covered with tens of thousands of sensory receptors for locating swarms of zooplankton, which is their primary food source. American paddlefish are native to the Mississippi River basin and once moved freely under the relatively natural, unaltered conditions that existed prior to the early 1900s. Paddlefish commonly inhabited large, free-flowing rivers, braided channels, backwaters, and oxbow lakes throughout the Mississippi River drainage basin, and adjacent Gulf drainages. Their peripheral range extended into the Great Lakes, with occurrences in Lake Huron and Lake Helen in Canada until about 90 years ago.

The Florida sand darter (Ammocrypta bifascia) is a species of freshwater ray- finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is endemic to Gulf Coast drainages from the Aplalachicola to the Perdido River in Florida and southern Alabama. It inhabits streams with waters that are clear to tannin-stained where there are shifting sand bottoms and a moderate to fast flow. It is most frequently encountered where there is a moderate current in medium-sized to large streams, but it will enter smaller streams on occasion.

Yellow poplar, northern red oak, white oak, basswood, cucumber tree, white ash, eastern hemlock and red maple are found in colluvial drainages, toeslopes and along flood plains of small to medium-sized streams. White oak, northern red oak, and hickory dominate on the north and west, while chestnut oak, scarlet oak and yellow pine are found on ridgetops and exposed sites. The area has been the source of numerous sitings of the orangefin madtom. The area contains part of the Central Appalachian Shale Barrens where the rare Virginia white-haired leatherflower is found Several rare shale barrens biological communities are found here.

The primary capability of TLS is the generation of high resolution 3D maps and images of surfaces and objects over scales of meters to kilometers with centimeter to sub-centimeter precision. Repeat TLS measurements allow the imaging and measurement of changes through time and in unprecedented detail, making TLS even more valuable for transformative science investigations. TLS is a powerful geodetic imaging tool ideal for supporting a wide spectrum of user applications in many different environments. Geoscience applications to date include detailed mapping of fault scarps, geologic outcrops, fault-surface roughness, frost polygons, lava lakes, dikes, fissures, glaciers, columnar joints and hillside drainages.

Emergency departments in the military benefit from the added support of enlisted personnel who are capable of performing a wide variety of tasks they have been trained for through specialized military schooling. For example, in United States Military Hospitals, Air Force Aerospace Medical Technicians and Navy Hospital Corpsmen perform tasks that fall under the scope of practice of both doctors (i.e. sutures, staples and incision and drainages) and nurses (i.e. medication administration, foley catheter insertion, and obtaining intravenous access) and also perform splinting of injured extremities, nasogastric tube insertion, intubation, wound cauterizing, eye irrigation, and much more.

The Growler Range has the distinction of being on a water divide between two northwest-draining washes to the Gila River. The Growler's are at the headwaters of Growler Valley west of the range which is the southeast drainage to the San Cristobal Wash. The north end of the range is south and southwest of Childs Valley which is part of the Tenmile Wash Drainage. The two drainages are at the beginning of the Gila River's turn from going south-to-west and exiting southwest Arizona with its confluence with the Colorado River at Yuma, Arizona-Winterhaven, California.

The Hayduke Trail is an backpacking route across southern Utah and northern Arizona. It "begins" in Arches National Park near Moab, Utah, before heading through the Needles district of Canyonlands National Park, Capitol Reef National Park, Bryce Canyon National Park, the Grand Canyon National Park and ending in Zion National Park. This highly strenuous wilderness route is exclusively on public land and travels ridgelines, drainages, existing foot and game trails, dirt roads, and rivers. The highest point is Mount Ellen (Utah) in the Henry Mountains at above sea level to a low in the Grand Canyon of near .

Arctic grayling (Thymallus arcticus) is a species of freshwater fish in the salmon family Salmonidae. T. arcticus is widespread throughout the Arctic and Pacific drainages in Canada, Alaska, and Siberia, as well as the upper Missouri River drainage in Montana. In the U.S. state of Arizona, an introduced population is found in the Lee Valley and other lakes in the White Mountains. They were also stocked at Toppings Lake by the Teton Range and in various lakes in the high Uinta Mountains in Utah, as well as various alpine lakes of the Boulder Mountain chain in central Idaho.

Several Late Miocene [about 7 million years ago (Mya)] trout-like fossils in Idaho, in the Clarkia Lake beds, appear to be of Oncorhynchus. The presence of these species so far inland established Oncorhynchus was not only present in the Pacific drainages before the beginning of the Pliocene (5–6 Mya), but also that rainbow and cutthroat trout, and Pacific salmon lineages had diverged before the beginning of the Pliocene. Consequently, the split between Oncorhynchus and Salmo (Atlantic salmon) must have occurred well before the Pliocene. Suggested dates have gone back as far as the Early Miocene (about 20 Mya).

The composition and structure of the ground surface beneath the snowpack influences the stability of the snowpack, either being a source of strength or weakness. Avalanches are unlikely to form in very thick forests, but boulders and sparsely distributed vegetation can create weak areas deep within the snowpack through the formation of strong temperature gradients. Full-depth avalanches (avalanches that sweep a slope virtually clean of snow cover) are more common on slopes with smooth ground, such as grass or rock slabs. Generally speaking, avalanches follow drainages down-slope, frequently sharing drainage features with summertime watersheds.

The Hot Creek geothermal field is within from the Lunar Crater volcanic field but does not appear to have its heat source there. Erosion has led to topographic inversion at some volcanoes, forming lava-capped mesas (hills with flat tops), broadening and flattening volcanic cones and has led to the formation of soils and drainage networks especially on older vents; additionally, desert pavement and wind-transported material has accumulated on some lava flows. The Lunar Lake playa is located in the northern part of the volcanic field; it lies at elevation and collects water from local drainages, which only ephemerally contain water.

The area now is managed almost exclusively for beef production with annual burns and intensive grazing practices that provide little of the habitat structure required to support many priority bird species. Historically, fire, drought, and plains bison were dominant ecological forces and had great influences on the vegetation from local to landscape scales. The Osage Plains and Flint Hills were dominated historically by tallgrass prairie with scattered groves of blackjack oak (Quercus marilandica) in the uplands and along drainages. A variety of wetland types, including wet prairie, marshes, and northern floodplain forests occurred along larger rivers.

There are several major threats to the Big Sandy crayfish. Pollution and high sediment values in the water supply can ruin a crayfish habitat. This usually occurs from mining, timbering, and the use of unpaved roads by off-road vehicles, causing high levels of erosion that go directly into the water streams and supplies often found at the bottom of valleys where the Big Sandy crayfish lives and thrives. Additionally, other problems and threats to water quality include sewage discharges and chemical drainages from paved roads and landmines which all can infect a water supply the crayfish are inhabiting.

On the north side, with cool and wet colluvial drainages, the overstory is dominated by yellow popular, northern red oak, white oak, basswood, cucumber tree, white ash, eastern hemlock and red maple. A significant northern hardwood forest community, between 4000- and 4800-feet elevation, is dominated by American beech, yellow birch, sugar maple, mountain maple and striped maple. Above 4200 feet red spruce is found throughout the area. Although most of the timber is in the 21-100 year old age class, there are areas at high elevations where logging was limited by steep and rocky slopes.

Elsewhere in the region, recent river surveys in Java have not recorded its presence, despite the island being the locality of the species holotype. Historical records from Myanmar, the Ganges River in India, and the Bay of Bengal (the latter two as Trygon fluviatilis) have similarly not been corroborated by any recent accounts. Disjunct populations of the giant freshwater stingray in separate river drainages are probably isolated from one another; though the species occurs in brackish environments, there is no evidence that it crosses marine waters. This is a bottom-dwelling species that favors a sandy or muddy habitat.

The hike climbs over the crest of the shale formed, north-south oriented Spring Mountain Ranges, and rewards the hiker with panoramic views of the Red Rock Escarpment below. A marked trail along the crest descends to the sandstone escarpment. Here, steep free climbing down a chimney—possible without technical gear—takes the hiker to a narrow neck of rock that separates the drainages of Pine Creek to the south and Icebox Canyon to the north. The hike is marked by cairns that show the route to proceed up toward the base of a cliff, angling left just above the northern drop-off.

The Wehana–Tucannon Wilderness consists primarily of rugged basaltic ridges separated by deep canyons with steep slopes. The area's precipitation drains south into the Wenaha River, east to the Grande Ronde River and Asotin Creek, and north into the Tucannon River, each part of the Snake River watershed. To the west drainages are the Touchet River and Mill Creek, both leading to the Walla Walla River, and the Umatilla River, a direct tributary of the Columbia River. The Wilderness ranges in elevation from on the Wild and Scenic Wenaha River to atop Oregon Butte at in Washington.

Pine Creek flows east-southeast through the northeastern part of the county to discharge into the Mississippi, while Crooked Creek flows east across the southern part of the county to discharge into the Mississippi. The county's terrain consists of low rolling hills on its western end, transitioning to hills carved with drainages toward the east.Houston County MN Google Maps (accessed March 12, 2019) The central and western portion of the county is a plateau with its highest point at 1,273' (388m) ASL, near its southwest corner. The county has a total area of , of which is land and (2.9%) is water.

Many native populations were displaced by non-natives, but there was quality brown and rainbow trout fishing in the Firehole, Madison and Gibbon river drainages. Stocking and hatchery operations had had an overall negative impact on the Yellowstone cutthroat and Westslope cutthroat populations and in 1953 the National Park Service began closing the hatcheries and stopping stocking operations. The last fish stocked for the benefit of anglers was in 1955 after some 310 million fish had been released in park waters since 1889. The regulation of anglers in the park also evolved significantly since the park's creation.

Lowndes County lies on the east side of Mississippi, bordering the U.S. state of Alabama. Its terrain was completely wooded before settlement; at present its more level areas have been cleared and turned to agricultural or urban use, with the drainages (about 40% of the total area) still wooded.Lowndes County MS (Google Maps, accessed 24 September 2020) The Tennessee−Tombigbee Waterway flows south-southeastward through the center of the county, with a significant lock system (John C. Stennis Lock and Dam) near Columbus. The county's highest point (450 feet/137 meters ASL) is a small rise near the county's NE corner.

The Rum River flows south through the county, originating from Mille Lacs Lake. It is joined by the West Branch of the Rum River, which rises in northwest Mille Lacs County and flows south-southeast to its confluence with the Rum at Princeton. The county terrain consists of wooded rolling hills, carved by drainages, with open areas devoted to agriculture.Mille Lacs County MN Google Maps (accessed May 3, 2019) The terrain slopes to the south and east, with its highest point at one mile (1.6 km) from the southwest shoreline of Mille Lacs Lake, in Mille Lacs Kathio State Park.

When the Washburn and Hayden parties traveled through the Firehole River and Gibbon River basins in the 1870s, the Gibbon River above Gibbon Falls was barren of fish, the falls being a natural barrier to upstream migration. Unlike the Yellowstone drainage, the upper Gibbon was isolated from any connection to drainages on the Pacific slope. The absence of fish was overcome in 1890 when the first Rainbow trout were introduced into the river above the falls. In 1920, Arctic Grayling, native in the Gibbon and Madison Rivers below the falls were stocked in Grebe Lake at the headwaters of the Gibbon.

Fast flowing clear mountain streams flow to the valley floors of the two basins to yield a more turbid water quality, especially during periods of peak rain. This site is known worldwide as the premier habitat for the jaguar (Panthera onca), which is most often found in the vast almost unexplored West Basin wilderness. The riparian zone forest areas generally feature lush broadleaf rainforest intruding into the verges of fast flowing steep mountain streams as well as the languid meandering valley drainages. There are particularly interesting assemblages of vegetation along the rocky bedded mountain streams which have frequent rapids, waterfalls and deep pools.

The Scioto River flows southward through the center of Pickaway County. Big Darby Creek drains the upper western part of the county, discharging into the Scioto at Circleville, and Deer Creek drains the lower western part of the county, flowing southward into Ross County. The county terrain consists of low rolling hills carved with drainages; all available areas (87%)About Pickaway County (accessed 10 June 2019) are devoted to agriculture.Pickaway County OH - Google Maps (accessed 10 June 2019) The terrain's highest point (1,090' or 332 m ASL) lies on the county's east border, 2.4 miles (3.9 km) east-northeast of Hargus Lake.

The range's highest peak is Picacho del Diablo at in elevation. Also known as Cerro de la Encantada (Enchanted Mountain) and Picacho la Providencia (Providence Peak), it is the highest point in Baja California state and of the entire Baja California Peninsula. Moon Travel Guides: "Parque Nacional Sierra San Pedro Mártir in Baja, Mexico" The range is a drainage divide that demarcates the drainages flowing west into the Pacific Ocean or east into the Gulf of California for this section of the Baja California Peninsula. Snow is usually present at the highest elevations in the winter.

Summit Lake, elevation 710 m (2329 ft), is a lake in the Central Interior of British Columbia, Canada, located to the north of the city of Prince George. It is the namesake of the community of the same name, which lies alongside the John Hart Highway to the south of the community of McLeod Lake (Fort McLeod). It is at the head of the Crooked River, which flows north to McLeod Lake. Summit Lake is situated at the divide between the Fraser and Peace basins and so is at the divide between the Pacific and Arctic drainages.

The forest is composed mostly of broadleaf deciduous species with some yellow pine. About 1/3 of the area, with colluvial drainages, toeslopes and stream floodplains, has a rich habitat that supports yellow poplar, northern red oak, white oak, basswood, cucumber tree, white ash, eastern hemlock, and red maple. The remainder of the area, on the north and west slopes, contains white oak, northern red oak and hickory, and ridgetops and eastern slopes contain chestnut oak, scarlet oak and yellow pine. There are 77 acres of table mountain pine, one of Virginia’s few remaining stands of pure table mountain pine.

The spawning season is from October to early December, when water temperatures are 2–6 °C. The fish seek out areas of coarse gravels or cobbles at depths of at least , and scatter the non-adhesive eggs so that they sink into the interstices. The eggs then develop slowly through the winter (6–10 weeks), hatching in the early spring. This species occurs throughout the western half of North America, as far north as the Mackenzie River (Canada) and the drainages of the Hudson Bay, in the Columbia River, upper Missouri River, upper Colorado River, and so forth.

Lions Park The Cheyenne Community Recreation and Events Department operates an Ice and Events center, swimming pool, spray park, skateboard park, two golf courses, Cheyenne Botanic Gardens (including the Paul Smith Children's Village at the Gardens), paddle boat rentals in Lions Park (summers only), cemeteries, forestry operations, community house, Youth Activity Center and a miniature golf park. The Cheyenne Parks and Recreation Department also operates a ) Greater Cheyenne Greenway system. The greenway connects parks and neighborhoods of greater Cheyenne. It includes many bridges and underpasses where travelers can avoid high traffic roads and travel above waterways and drainages.

A major central wash follows the valley's southeast; the north has no major wash, and instead drainages are towards a central bajada landform region. The northern bajada extends north past Hachita, NM on the east and Old Hachita, NM on the west. The southeasterly excursion of the valley is caused by the bordering Big Hatchet Mountains on the southwest, which trend southeast; the valley narrows here, between the Apache Hills northeast, to between 5 and 7 miNew Mexico Atlas & Gazetteer, p. 52-53. wide. In the northwest where the valley widens, the Little Hatchet Mountains lie on the west perimeter.

The cypress darter (Etheostoma proeliare) is a species of freshwater ray- finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is endemic to fresh waters of the central and eastern United States. Its range includes drainages from the Choctawhatchee River, Florida, to the San Jacinto River, Texas, as well as the Mississippi River basin from southern Illinois and eastern Oklahoma to the Gulf of Mexico. It inhabits vegetated margins of swamps and lakes, and backwater habitats during the summer, while in winter it moves to flooded riffles and backwater bayous.

Percina maculata-distribution Blackside darter is found in areas of small to medium-sized rivers and streams, that are clean and free of most pollution. The areas they are found will have slower current and have spaces to hide like roots and natural debris. These fish are widespread in the United States and can be found in the Hudson Bay, Mississippi River basin, and the Gulf drainages from Mobile Bay in Alabama to the Calcasieu River in Louisiana. They have also been found in the Minnesota river basin, Whetstone Creek, Big Sioux basin, Pipestone, and other areas around the Great Lakes.

The Cheyenne River flows east-northeastward along the southern boundary of Ziebach County. The Moreau River flows eastward through the upper portion of the county, and Cherry Creek flows southeastward through the lower portion, draining the area into the Cheyenne River. The terrain is composed of semi-arid rolling hills interrupted by buttes and carved by drainages and gullies, partly devoted to agriculture and cattle.Ziebach County SD Google Maps (accessed 9 February 2019) The terrain slopes to the south and the east; its highest point (except for the isolated Thunder Butte, at 2,733') is near its NW corner at 2,582' (787m) ASL.

The terrain of Anderson County consists of hills carved by drainages and gullies, with numerous lakes and ponds. The Trinity River flows southward along the west boundary line of the county; the Neches River flows southward along its east boundary line, and Brushy Creek flows southeastward through the central portion of the county.Anderson County TX Google Maps (accessed 12 February 2019) The terrain slopes to the south and east, with its highest points along the midpoint of its northern boundary line at 551' (168m) ASL. The county has a total area of , of which are land and (1.4%) are covered by water.

The Continental Divide National Scenic Trail (in short Continental Divide Trail (CDT)) is a United States National Scenic Trail running between Chihuahua and Alberta. It follows the Continental Divide of the Americas along the Rocky Mountains and traverses five U.S. states -- Montana, Idaho, Wyoming, Colorado, and New Mexico. In Montana it crosses Triple Divide Pass (near Triple Divide Peak which separates the Arctic Ocean, Atlantic Ocean and Pacific Ocean drainages.) The trail is a combination of dedicated trails and small roads and considered 70% complete. Portions designated as uncompleted must be traveled by roadwalking on dirt or paved roads.

Kokanee Glacier Provincial Park is one of the oldest provincial parks in British Columbia, established in 1922. The park has an area of and is located in the Selkirk Mountains in the West Kootenays region of BC. The park has three glaciers (Kokanee, Caribou, and Woodbury) that feed over 30 alpine lakes which are the headwaters of many creeks. There are five access roads entering the park, which were developed as mining and forestry roads along the major drainages. The nearest towns are Nelson, Ainsworth, Kaslo and Slocan City (access is primarily from Nelson and Kaslo).

Cross-section of cirque erosion over time Glaciers, typically forming in drainages on the sides of a mountain, develop bowl-shaped basins called cirques (sometimes called ‘corries’ - from Scottish Gaelic _coire_ [kʰəɾə] (a bowl) - or s). Cirque glaciers have rotational sliding that abrades the floor of the basin more than walls and that causes the bowl shape to form. As cirques are formed by glaciation in an alpine environment, the headwall and ridges between parallel glaciers called arêtes become more steep and defined. This occurs due to freeze/thaw and mass wasting beneath the ice surface.

Canaan Mountain Wilderness scarlet monkeyflower Most of the area is dominated by ponderosa pine and Douglas fir scattered among large areas of slickrock. Pinyon pine, manzanita, Gambel oak, and Indian ricegrass are found on the pockets of soil amid the slickrock. The lower slopes on the eastern side of the wilderness and at the base of the White Cliffs support pinyon-juniper with serviceberry, manzanita, and various grasses. Riparian areas are found along South Creek, Water Canyon Creek, Squirrel Creek and several other drainages; maidenhair fern, shooting star, scarlet monkeyflower, and columbine grow in hanging gardens by cliff- side springs and seeps.

These shiners are typically found in the waters of Cochise County and San Bernardino Creek. They were extirpated from the United States for a brief period during 1969-70, but they have recently been reintroduced to Arizona and other regions of the Southwest. The San Bernardino Wildlife Refuge has been working for the recovery of this threatened species by reintroducing it into various ponds around Cochise County. After the reintroduction in 1990, the beautiful shiner has made its way from Cochise County to Southern parts of Sonora and Mexico, traveling to the Santa Maria and Santa Clara drainages to spawn.

The Gila chub has been found in streams of the Gila River drainage in Arizona, and in the Santa Cruz River system in Sonora, Mexico; however, recently, the Gila chub species has not been documented in the San Pedro drainage in Sonora, Mexico. The Gila chub has also been recently discovered in these specific drainages in Arizona: Santa Cruz River, Middle Gila River, San Pedro River, Agua Fria River, and the Verde River. These fish have also been extirpated from the Monkey Spring of the Santa Cruz River, and Fish and Cave Creeks of the Salt River.

The western blacknose dace inhabits the upper Mississippi, Ohio, and Great Lakes drainages, from as far north as south-central Canada to northern Alabama and Georgia and east to eastern Lake Erie. Young daces prefer to inhabit shallower, quiet pools with silty bottoms while more mature daces prefer streams with consistently high turbulence patterns and plenty of places to hide since they are a prey species. Most often they occupy water depths ranging from 100 to 200 mm with gravel or cobble bottoms. They can also be found in riffles hiding under large rocks or boulders.

The steep valleys trending to the west contain high and medium gradient rivers and streams that support cold water salmonids, including the threatened Chinook salmon, steelhead, and bull trout. Notable river drainages in Oregon include the North Umpqua, North and Middle Forks of the Willamette, McKenzie, North Santiam, South Santiam, Clackamas, Salmon and Bull Run River watersheds; and in Washington, the Lewis, Cowlitz, Nisqually, Puyallup, White, and Green River watersheds. Reservoirs store winter snowmelt for irrigation and municipal water supply in the Willamette Valley. The Westerns Cascades Lowlands and Valleys is the largest of the Cascades subregions, covering in Oregon and in Washington.

Schistura namboensis is a species of ray-finned fish, a stone loach, in the genus Schistura. It normally occurs in the rapids and riffles of medium-sized rivers and streams but it can also be found in reaches with a slow current and sandy substrate. This species appears to have some resistance to organic pollution and occurs in streams flowing through settlements, and is often the last fish species to remain in such streams. It is found in the coastal drainages in southern and central Vietnam and also in Laos in some rivers which rise there before flowing into Vietnam.

Approximately 338 acres (1.4 km2) of the land is used for corn and soybean production under a Cooperative Farm Agreement. Fields of warm season grasses such as big bluestem (Andropogon gerardi), little bluestem (Schizachyrium scoparium), Indiangrass (Sorghastrum nutans), sideoats grama (Bouteloua curtipendula), switchgrass (Panicum virgatum), and eastern gamagrass (Tripsacum dactyloides) cover 260 acres (1.1 km2) of land. of hardwood forest has been planted to help control the erosion. There are an additional of erosion drainages which are being converted to grassland or hedgerow habitat, being used as shallow water areas, and of hardwood forests consisting primarily of oak and hickory trees.

The gilded barbet ranges in the eastern Andes drainages to the rivers of the western Amazon Basin from eastern Colombia-Venezuela, eastern Ecuador, from north to south- eastern Peru, and northern Bolivia; in Bolivia the barbet only ranges on the headwater tributaries to the north-easterly flowing Madeira River. The eastern limit in the south-west Amazon Basin is the Purus River west of the Madeira. In the north-west Amazon Basin, the eastern range limit is central Roraima state Brazil, the south flowing Branco River. The contiguous range to the north-west into Venezuela is all of eastern Venezuela approaching the Guyana border.

The blue chub (Gila coerulea) is a cyprinid fish found in the Klamath River and Lost River drainages of far northern California and southern Oregon. Relatively slender among chubs, it has larger eyes than most and a terminal mouth that extends back nearly as far as the forward edge of the eye. Color is a nondescript dusky shade on the back and silvery on the sides; the name comes from the males at breeding time, whose snout becomes noticeably blue, along with orange tinges on the sides and the fins. There are 9 rays in the dorsal fin, 8-9 in the anal fin, and 14-17 in each pectoral.

Unless violently expelled and generally speaking, larger sized tephra falls closest to the crater and smaller tephra landing farther away, with its distribution more highly influenced by prevailing wind velocity and direction. Once initially established, a pyroclastic dam's continued longevity remains a balance between its slowly consolidating hardness and toughness, and the amount and velocity of flowing water's erosive capacity to remove it from its outset. Unconsolidated tephra is quickly moved by precipitation and flowing water in drainages, at times creating a lahar. Upstream of the dam this material would rapidly accumulate to fill the lake, and downstream it would tend to erode its slopes and base.

In 1938, a area surrounding Teakettle Creek was designated the Teakettle Experimental Area and five drainages were chosen for study. Stream gauge stations and sediment basins were built in the 1940s. Research collaborators have come from the following institutions and agencies: California State University, Michigan Technological University, National Aeronautics and Space Administration- Goddard Space Flight Center, Oregon State University, University of California, Berkeley, University of California, University of Maryland, Virginia Commonwealth University, Universidad Metropolitana, University of Michigan, University of Nevada, University of Washington, USDA Forest Service, Forest Inventory and Analysis Program, Sierra National Forest, and Southern Research Station. There is a bunkhouse cabin, dry laboratory, and storage garage.

Rim ticking (widely spaced spots of paint on rims) occurs, suggesting a possible link to earlier white wares of the Mesa Verde region. Hawley (1950:69) asserted that in the central and western portion of its range, Galisteo Black-on-white “is so similar to Mesa Verde Black on White that it can be distinguished only by detailed observations.” A somewhat cruder local variant with soft paste, Rowe Black-on-white, was made in the upper Santa Fe and upper Pecos drainages (Hawley 1950:69; Wilson 2005:35). Jemez Black-on-white jar A fourth series of types was made in the Jemez River drainage.

Arctic Pacific Lakes Provincial Park is a provincial park in British Columbia, Canada, protecting a pair of lakes known as Arctic and Pacific Lakes, which as their name indicate are on the divide between the Pacific and Arctic drainages. Inherently, the Continental Divide runs between the two lakes, which lie in a narrow valley amid the rugged mountains of the northwesternmost McGregor Plateau. The pass formed by the lakes was important during early fur trade operations and was one of the main links between New Caledonia and the fur companies' eastern territories beyond the Rockies. The park is located 90 kilometres northeast of Prince George, British Columbia and is 13,887 ha.

Piner Creek before its confluence with Santa Rosa Creek, on the Santa Rosa Plain As recently as the Miocene period, twelve million years ago, the entire watershed of Piner Creek was on the floor of the Pacific Ocean. After significant volcanic uplift and tectonic movement, the headwaters region of the Mayacmas Mountains emerged above the ocean. Piner Creek was one of the drainages that began to drain the new landmass, in formation of the eventual Santa Rosa Plain, through which the middle and lower reaches of Piner Creek flow. Occasional basaltic outcrops are seen in the upper reach of Piner Creek, betraying the volcanic origin of the Mayacmas Mountains.

In the case of a major Plinian eruption, at least 60,000 to 70,000 people would be threatened. Rock fall would affect the area close to the summit domes, as would pyroclastic flows; these would be a further hazard to the valleys draining the volcano. The presence of an ice cap is an additional source of danger, as its melting during a volcanic eruption could form hazardous lahars, although the small volume of the ice cap limits their damage potential. The Majes River and Sihuasi River drainages would be threatened by such mudflows in case of an eruption; the former is the site of a major irrigation project.

In Arizona, the Yaqui longfin dace only occurs in the southeast, in Cochise County (in both the endorheic Sulphur Springs (Willcox Playa) and Río Yaqui drainages). However, it is also found in northern Mexico, in the Yaqui, Sonora, Mayo, Fuerte and Sinaloa River Basins of Sonora and Sinaloa. The Yaqui longfin dace was re-introduced into the Yaqui River on the San Bernardino Wildlife Refuge and the Leslie Creek Wildlife Refuge including West Turkey Creek at Rucker Canyon. The Yaqui longfin dace has the same elevation restrictions as the Gila longfin dace, ranging only below 1484 m, with records of up to 2030 m.

The primary purpose for which the Refuge was created is its "...particular value in carrying out the national migratory bird management program." The Refuge's interspersion of wetland, forested upland and old field habitats is ideally suited for this purpose. The Refuge supports a diverse mix of migratory birds including waterfowl, wading birds, raptors, shorebirds, passerines, as well as resident mammals, reptiles, amphibians, fish and invertebrates. The extensive and regionally significant wetlands occurring on and adjacent to the Oxbow Refuge, including their associated tributary drainages and headwaters, have been listed as a priority for protection under both the North American Waterfowl Management Plan and the Emergency Wetlands Resources Act of 1986.

Red Buttes Wilderness is situated in both Oregon and California and includes the crest of the Siskiyou Mountains between the Rogue River and Klamath River drainages. The wilderness is long and wide, with elevations ranging from in Butte Fork Canyon to at the east summit of the Red Buttes.Rogue River–Siskiyou National Forest - Red Buttes Wilderness The main waterways that flow through Red Buttes Wilderness are all part of the Rogue River watershed, including the Butte Fork and the Middle Fork of the Applegate River, as well as Sucker Creek, a tributary of the Illinois River. The Wilderness contains the headwaters of the Illinois River.

Mount McLoughlin in the Sky Lakes Wilderness Geologic studies indicate that the earliest rocks in this part of the High Cascades began forming when a chain of volcanoes erupted between five and three million years ago. During the last glacial period, the composite volcanoes of Mount Mazama and Mount McLoughlin began their initial build-up. On their north and east slopes, Mount McLoughlin and other peaks bear scars caused by glaciers. Like most other major drainages within the Sky Lakes Wilderness, Seven Lakes Basin and the deep canyon of the Middle Fork of the Rogue River were carved by the massive ice fields that covered the highest elevations of the Cascades.

The land district comprises all those parts of the Kootenay River and Columbia River basins in the southeast corner of the province, excepting the drainages of the Okanagan, Granby, Sanpoil and Kettle Rivers, i.e. all those sub-basins of the Columbia on the west and south of the summit-line of the Monashee Mountains. Also not in the land district is the northernmost part of the Columbia's basin, north of Boat Encampment and Mica Creek, northwest of which is the Cariboo Land District. To the Kootenay Land District's west is the Yale Land District, which includes the Kamloops- Shuswap, Okanagan and Boundary Country regions of the province.

Tyson Wash is one of the larger eastern-bank dry washes that enter the Colorado River in western Arizona. It drains the La Posa Plain south-to-north and is also coincident with the Plain, (southern two thirds). Tyson Wash is the southwest drainage of a pair of drainages, the other being the Bouse Wash drainage. They are in the Lower Colorado River Valley, south of Parker, Arizona and both enter the region east of the Colorado River, with no Colorado River confluence; they both end at regions on the eastern border of the Colorado River Indian Reservation located along the Colorado River in the Parker Valley.

The hydrological conditions in these areas likely were controlled by relatively uniform ice thickness and gentle topography. The seconed type of volcano-ice interaction is located only to the east, south and southwest of the Tanzilla Plateau, in the Cassiar Mountains, Skeena Mountains and in the Boundary Ranges. Volcanic activity in these locations is also largely mafic in composition, but the extensive elevations of these areas had a much more impressive influence on glaciation and subglacial volcanism. High altitude glaciation took over when the Cordilleran Ice Sheet was not present and even when buried by the Cordilleran Ice Sheet, basal ice movement was strongly influenced by the deep, pre-glacial drainages.

The former hunting grounds of the Oglala Lakota, it has become the single largest source of coal mined in the United States, and contains one of the largest deposits of coal in the world. Most of the active coal mining in the Powder River Basin actually takes place in drainages of the Cheyenne River. Because of the Powder River Basin, Wyoming has been the top coal-producing state in the United States since 1988. In 2007, the Powder River Basin alone produced 436 million short tons (396 million tonnes) of coal, more than twice the production of second-place West Virginia, and more than the entire Appalachian region.

Little Pine Mountain is a mountain in Santa Barbara County, California, in the Los Padres National Forest at the southern edge of the San Rafael Mountains. It separates the drainages of Oso Creek, which flows into the upper Santa Ynez River, from the drainage of Santa Cruz Creek, which flows into the middle section of the river via Lake Cachuma. The mountain is named for a thin grove of Coulter pines located on the summit. The mountain is reached by the Santa Cruz National Recreation Trail, and is a popular day hike and mountain biking route for residents of Santa Barbara during the winter months.

The American Mediterranean Sea drains approximately in North America and Caribbean South America; it is the 2nd largest sea watershed. The watershed depends on South American water bodies such as the Magdalena River with , as well as the Guajira Peninsula and the Gulf of Venezuela. Central American drainages include those of/to the Belize River, Gulf of Honduras, Caratasca Lagoon, Nicaraguan Caribbean Lowlands, and the Colorado River in Costa Rica. In North America, the sea mostly drains by the Mississippi River basin of , to the east of the Continental Divide of the Americas, while it drains approximately from the Rio Grande and from the Yucatan Peninsula.www.britannica.com.

The Bidahochi Formation abuts the Defiance Plateau to the east and northeast; it was uplifted by the Defiance Uplift and is a mountainous, flattened upland. Except the Defiance Plateau's connection in the central-northeast to New Mexico mountains and river drainages, the entire Defiance Plateau is part of the Colorado River drainage. The north-northwest of the Bidahochi abuts the southeast Black Mesa (Arizona), with drainage to east, then north through Chinle Valley (Chinle Wash) to the San Juan River, a southeast tributary to the Colorado River. The drainage from the Black Mesa southwest is towards the Little Colorado River, another southeast tributary of the Colorado River.

The Sokhondo Reserve is in a mountainous area of the trans-Baikal region (east of Lake Baikal). The two main peaks (Big Sokhondo and Little Sokhondo) are within 100 meters of each other in height, but are separated by rivers and valleys. To the southeast of the Sokhondo massif is the Altan-Kyra Depression, an area of Mongolian steppe character. The mountains of Sokhondo are on the continental divide between the Pacific and Arctic drainages, with some rivers flowing into the Yenisei River and north, while others flow to the Onon River which is one of the main tributaries of the Amur River to the east.

Two tiger oscars A. ocellatus is native to Peru, Ecuador, Colombia, Brazil, and French Guiana, and occurs in the Amazon River basin, along the Amazon, Içá, Negro, Solimões, and Ucayali River systems, and also in the Approuague and Oyapock River drainages. In its natural environment, the species typically occurs in slow-moving white-water habitats, and has been observed sheltering under submerged branches. Feral populations also occur in China, northern Australia, and Florida, USA as a byproduct of the ornamental fish trade. The species is limited in its distribution by its intolerance of cooler water temperatures, the lower lethal limit for the species is 12.9 °C (55.22 °F).

The Stephen Mather Wilderness provides a protected area for a wide variety of wildlife, including elk, mule deer, gray wolf, mountain goat, moose, and bighorn sheep. Species of wolverine, bat, duck, hawk, owl, frog, loon, chipmunk, coyote, squirrel, bear, falcon and eagle are also fairly common.State of the Stephen Mather Wilderness 1994 - NPS There are approximately twenty-eight species and subspecies of fish found in the wilderness, including the threatened bull trout and anadromous runs of coastal cutthroat trout, Dolly Varden, steelhead, and five species of salmon found in the Skagit, Nooksack, and Chilliwack drainages. Threatened or endangered wildlife species in the area include bull trout (threatened) and northern spotted owl.

Some of its glacial ice feeds the Avalanche Glacier below it to the southwest while the rest tumbles over some large cliffs to its diminutive lower section to the west. The White Salmon and Avalanche Glaciers feed the many streams of the Salt Creek and Cascade Creek drainages, which flow into the White Salmon River. The Pinnacle Glacier is the source of a fork of the Lewis River as well as Riley Creek, which is also a tributary of the Lewis River. The south side of the mountain along Suksdorf Ridge is moderately glacier-free, with the only glaciers being the relatively small Gotchen Glacier and the Crescent Glacier.

The company was chartered on October 2, 1897, to build a railroad between the Baltimore and Ohio Railroad at Johnstown and the Altoona and Philipsburg Connecting Railroad (A&PC;) at Ramey. The line would climb north from Johnstown along Hinkston Run to Ebensburg, and turn east to cut across the drainages to Loretto. From there, it would follow the PRR's Cresson and Irvona Branch, connecting with the Altoona and Beech Creek Railroad (A&BC;) at Dean before turning away to cross the Pennsylvania and Northwestern Railroad at Utahville and descending to Ramey. It obtained a lease of the A&PC; on October 20, 1897.

Goshute Canyon Wilderness is a wilderness area in northern White Pine County in the U.S. state of Nevada. Located in the Cherry Creek Range north of the town of Mcgill, the Wilderness was created by the "White Pine County Conservation, Recreation and Development Act of 2006" and is administered by the U.S. Bureau of Land Management.Goshute Canyon Wilderness - Friends of Nevada Wilderness Vegetation in the Wilderness consists primarily of thick pinyon pine and juniper stands at the lower elevations, while bristlecone and limber pine thrive in the higher elevations. Aspen and cottonwood trees crowd the moist drainages along the creeks that flow through the Wilderness.

The extent of internal drainage, the area in which surface water cannot reach the ocean, defines the geographic region called the Great Basin. The Great Basin's internal drainage results from blockage of water movement by high fault-created mountains and by lack of sufficient water flow to merge with larger drainages outside of the Great Basin. This internally-drained area occupies approximately , including most of Nevada, a large part of Utah, and portions of Idaho, California, and Oregon. Much of the present-day Great Basin would drain to the sea, just as it did in the recent Ice Ages, if there were more rain and snowfall.

The Tübatulabal's traditional homelands extended over including the Kern and South Fork Kern Rivers drainages (located in the Kern Valley area of California) extending from very high mountainous terrain in the north to about below the junction of the two rivers in the south. The high mountains in the north () are interspersed with lakes and meadows. The southern area () has three connected valleys: Kern Valley, South Fork Kern Valley, and Hot Springs Valley, where summers are hot and winters cold and rainy. The valleys are grasslands and chaparral with cacti, scrub oaks, willows, elderberry, and cottonwoods as primary vegetation with some joshua trees, junipers, piñons, oaks, and sugar pines.

Porter County lies on the northern edge of Indiana; its north border is formed by Lake Michigan and its south border is formed by the westward-flowing Kankakee River Its once-tree-covered low rolling hills have been cleared and devoted to agriculture; the only exceptions in Porter County are the drainages carved into the terrain, which are brush-filled. The East Arm Little Calumet River flows westward through the upper portion of Porter County.Porter County IN (Google Maps, accessed 24 August 2020) The highest point, at ,(PeakBagger.com, accessed 24 August 2020) is a small hill on the county's east border, 2.75 miles (4.4 km) NW of Westville.

The low, rolling hills of Shelby County are lightly carved by drainages, but are otherwise completely devoted to agriculture or urban development. The western edge of the county is drained by Sugar Creek, flowing south-southwestward into Johnson County. The central and SW parts of the county are drained by Big Blue River, flowing south- southwestward into Johnson County. The lower part of the county is drained by Flatrock River, flowing southwestward into Bartholomew County.Shelby County IN (Google Maps, accessed 14 August 2020) The terrain slopes to the southwest, with its highest elevations (930 feet/283 meters ASL) along the eastern part of its northern border with Hancock County.

The hills of Martin County are largely wooded and cut with drainages;Martin County IN (Google Maps, accessed 2 August 2020) the available area is devoted to agriculture, development, or is under control of the US Government - about a third of the county belongs to the Naval Surface Warfare Center Crane Division, and about a quarter of the county belongs to Hoosier National Forest. The highest point (870 feet/265 meters ASL) is in Mitcheltree Township, within NSWC Crane.Martin County High Point, Indiana (PeakBagger.com, accessed 2 August 2020) The East Fork of the White River flows southwestward through the lower part of the county.

The large-scale loach (Paramisgurnus dabryanus) is a species of true loach that is native to Mainland China, Hainan, Taiwan, Korea, and the Russian Far East. It can be found in water bodies such as the Yangtze Basin, Pearl River, Amur River, and various other drainages. There are several known invasive populations in places such as Barcelona, the San Joaquin River in California, and the majority of Japan. The large-scale loach is typically brown, grey, or golden in color with mottled or speckled black dots, which leads to it sometimes called a "peppered loach" when sold at pet stores (though it is more often misidentified as the pond loach instead).

The type of earlier pottery, in quoting James L. Murphy, "cannot be distinguished from the late Middle Woodland Watson Ware of the upper Ohio Valley nor from the Late Woodland Peters Cordmarked Ware from the Scioto and Hocking Valley drainages". Murphy, in 1968, explained the dominance at the site of smooth-surfaced shell-tempered sherds has an even more striking similarity between the Hobson Site and the components in the Hocking Valley of the Fort Ancient Tradition. The archaeologist found 791 plain, shell tempered body sherds. Ten fragments of pottery were found having thick strap handles and two lug handles, with punctate and incised decoration.

The Babocomari River is a major tributary of the upper San Pedro River in southeastern Arizona. The river begins in the Sonoita Basin near the community of Elgin, Arizona, and flows eastward for approximately before merging with the San Pedro, just south of the Fairbank Historic Townsite in the San Pedro Riparian National Conservation Area. The Babocomari drains an area of about , including the northern Huachuca Mountains, the northwestern Canelo Hills, and the southern Mustang Mountains, and is one of three drainages of the Sonoita Basin, the other two being Sonoita Creek and Cienega Creek. Vegetation consists of riparian trees along the main channel and small marshy grasslands.

With the exception of the snails at Makaleha Springs, most of these populations have only been observed once or twice. Recently, two individual snails were reported from a single site in Limahuli Stream in the Hanalei District of Kauaʻi's north shore. However, if a viable population of Newcomb's snail exists in the Limahuli watershed, its location remains unknown, therefore Limahuli Stream is not considered to have a "population" of Newcomb's snails. Recent survey work conducted from 1994 to 2003, limits the known range of Newcomb's snail to small sites located in a total of six watersheds in north- and east-facing drainages on Kauaʻi.

Starting in the Pliocene, about 5 million years ago, the Los Angeles Basin experienced considerable tectonic subsidence; at the same time the San Gabriel River was depositing a huge alluvial fan, essentially an inland delta, radiating from the mouth of San Gabriel Canyon. This has combined with smaller alluvial fans from other drainages along the front range of the San Gabriels to form the flat valley floor. In the San Gabriel Valley, riverine alluvium deposits can be up to deep. On the coastal plain, San Gabriel River sediments are interbedded with those from the nearby Los Angeles River as well as marine sediments left behind from ancient sea level changes.

Pages 409-411 in Proceedings of the Sudden Oak Death Third Science Symposium. USDA Forest Service, Santa Rosa, CA. This method has detected P. ramorum at scales ranging from small, intermittent seasonal drainages to the Garcia, Chetco, and South Fork Eel Rivers in California and Oregon (144, 352, and 689 mi2 drainage areas, respectively). It can detect the existence of infected plants in watersheds before any mortality from the infections becomes evident. Of course, it cannot detect the exact locations of those infected plants: at the first sign of P. ramorum propagules in the stream, crews must scour the watershed using all available means to find symptomatic vegetation.

The Missouri River flows south-southeastward along the east boundary line of Morton County, and Cannonball River flows east-northeastward along the eastern portion of the county's south boundary line. The county terrain consists of low rolling hills, etched by gullies and drainages; the more level areas are devoted to agriculture.Morton County ND Google Maps (accessed 19 February 2019) The terrain generally slopes to the east and south, but also slopes into the river valleys, with the high point near the midpoint of the north boundary line, at 2,375' (748m) ASL. The county has a total area of , of which is land and (1.0%) is water.

Unlike many other members of Ancistrini, the ranges of most of the Lasiancistrus species are quite broad. Lasiancistrus species are found throughout the Amazon basin, the upper and middle of the Orinoco River basin, the Rupununi River basin (Essequibo River drainage), the Lake Maracaibo drainage, and drainages west of the Andes in Colombia and Panama to the Bayano River. The species of Lasiancistrus are most commonly found in small creeks, typically in swift flow. However, some of the streams where Lasiancistrus can be found are in the lowlands, and hypoxia has been observed in one such stream, suggesting that lowlands are not a barrier to the movement of these species.

In response to pressure from poaching and to worldwide decreases in salmon stocks, some along nine of the more productive salmon rivers are in the process of being set aside as a nature preserve. Stickleback species, particularly Gasterosteus aculeatus and Pungitius pungitius, also occur in many coastal drainages, and are likely present in freshwater as well. Cetaceans that frequent the highly productive waters of the northwestern Pacific and the Okhotsk Sea include: orcas, Dall's and harbour porpoises, humpback whales, sperm whales and fin whales. Less frequently, grey whales (from the eastern population), the critically endangered North Pacific right whale and bowhead whale, beaked whales and minke whales are encountered.

The Missouri River flows southeasterly along the northeastern boundary of Dunn County, and the Little Missouri River flows eastward across the center part of the county, to its confluence with the Missouri in the northeastern part of the county. The county terrain consists of semi-arid rolling hills, which are etched in the north and east by gullies and drainages to the river valleys.Dunn County ND Google Maps (accessed 17 February 2019) The terrain slopes to the east and north; its highest point is a hill at the southwestern corner, at 2,625' (800m) ASL. The county has a total area of , of which is land and (3.5%) is water.

Historic bridges downstream of Conemaugh River Lake Dam: 1864 railroad bridge pier, 1907 arch bridge, and 1952 railroad bridge The Kiskiminetas-Conemaugh river basin flows through scenic mountainous country that forms the heart of the historic coal-producing areas of western Pennsylvania. Before the Dam was constructed, the town of Livermore served the area between Blairsville and Saltsburg as an important stop along the former canal, as well as the railroad. The watershed is considered among the most degraded in the state, largely from abandoned mine drainages. The recovery of the river has been an important ongoing ecological management project of state and private agencies.

The Fremont people lived in the area of what is now Dinosaur National Monument before the 14th century, with archaeological evidence dating from 200 to 1300. Archaeologists first studied and named the Fremont culture along the Fremont River in south-central Utah and have since traced it through much of the Green and Colorado River drainages. The Fremont did not build large permanent dwellings; instead, they lived in small bands within natural shelters, such as rock overhangs or shallow caves, or small villages. They consumed plant foods, such as pine nuts, berries, and cactus fruits, as well as wild game, including mule deer, bighorn sheep, smaller mammals, and birds.

The terrain of Haakon County consists of semi-arid rolling hills, carved with gullies and drainages, partially devoted to agriculture. The Cheyenne River, a tributary of the Missouri River, flows northeastward along the county's north boundary line, and the Bad River flows east-northeastward through the lower part of the county, both heading for their discharge points into the Missouri.Haakon County SD Google Maps (accessed 3 February 2019) The terrain slopes to the northeast, and its highest point is near the midpoint of its western boundary line, at 2,802' (854m) ASL. Haakon County has a total area of , of which is land and (0.9%) is water.

After 10,000 years before present this drainage system disappeared and distinct pupfish species evolved. Pupfish may have entered Death Valley through the Owens River, or through an earlier Pliocene river system, probably forming an unified breeding population. The speciation of Cyprinodon nevadensis and Cyprinodon salinus may have occurred in just a few thousand years after the drying of Lake Manly. It is likely that the propagation of pupfish across the whole system took longer than this, as Lake Manly was never simultaneously connected to all three of its source drainages and pupfish would have had to enter the Death Valley system from the Gulf of Mexico over large distances.

Water quality and the health of vegetation has begun to decline in the area as salinity of surface runoff has increased and groundwater levels have risen. Lake Magenta has a wetland area located to the south, and is on the southern end of an chain of lakes from Lake Biddy in the north, through Lake Stubbs (and the town of Newdegate), Lake Buchan and Lake Lockhart. There are three other lakes nearby to the east: Lake Morris, Lake Royston and Lake Cobham. The lake is a broad flat-floored valley with long paleo-drainages to the north and more steeply incised drainage lines to the south.

The Upper Tanana territory once extended from the Donjek River into neighbouring Alaska. The Northern Tutchone territory included the lower Stewart River and the area south of the Yukon River on the White and Donjek River drainages. Closely related through marriages between various local bands, these two language groups were merged by the Canadian government into a single White River Indian Band in the early 1950s for administrative convenience. In 1961, the Canadian government combined the White River Band with the Southern Tutchone-speaking members of the Burwash Band at Burwash on Kluane Lake as the Kluane Band (subsequently the Kluane Tribal Brotherhood and then the Kluane Tribal Council).

This species of fish is usually found in small streams along river drainages of Northwest Georgia, Northeastern Alabama, and as more recent research suggests, southwest Tennessee. N. chrosomus is a freshwater, benthopelagic fish that inhabits riffles and pools with gravelly bottoms in creeks and small rivers and are usually found accompanied by genera of Campostoma. They are mainly insectivorous and although studies show the predominate prey of N. chrosomus come from the family Chironomidae, they are found to be more opportunistic feeders and are not very selective. The maximum age is typically two years for both sexes and sexual maturity occurs at one year of age.

Manly Dam Reserve is also home to the threatened Red-crowned Toadlet which is associated with the rocky ridges and drainages of the Hawkesbury Sandstone formation. There are a variety of native and introduced fish in the waters of the reserve. Native fish include species such as Climbing galaxias, Fire-tail Gudgeon, and Short-finned and Long-finned Eels. The Climbing galaxias inhabits some of the less disturbed creeks and is able to climb up wet rock faces and cliffs with the aid of ridges on its fins, can breathe through its skin, and has lived in this once remote area, for an estimated 60 million years.

Black Butte Swamp and Glaze Meadow were likely formerly shallow lakes, though they now serve as sumps for streams and drainages from the Cascades, which are located to the southwest. Black Butte Swamp is a particularly important sump for extensive drainage from the southwest, its basin water lapping against Black Butte's southern base. Because it is elevated about above the Metolius Springs, the swamp acts as a hydraulic head for the spring water keeping the flow of the springs constant, and ensuring that there is a net influx of water into the swamp. Any excess water exits through Indian Ford Creek to flow east then south past the city of Sisters.

Angiopteris is a genus of huge evergreen ferns from the family Marattiaceae, found throughout the paleotropics from Madagascar to the South Pacific islands. Species of smaller stature with elongate synangia and creeping rhizomes are sometimes segregated into the genus Archangiopteris, and a once- pinnate monotypic segregate genus has been called Macroglossum, but molecular data supports inclusion of these taxa within a broad concept of Angiopteris. Angiopteris evecta has been introduced and naturalized in Hawaii, Jamaica, and parts of Central America, where it has become an invasive weed in lower elevation drainages. They feature a large, erect, woody rhizome with a wide base supported by thick roots.

Six federally recognized tribes filed Nondalton Tribal Council et al. v. State of Alaska DNR with the Alaska Superior Court (Third Judicial District) on May 5, 2009. The suit challenged the validity of the 2005 Bristol Bay Area Plan, one of many Area Plans created and administered by the State of Alaska that, along with other State and Federal rules, define land status and the appropriate and legal uses of State land within the plan boundaries. The Bristol Bay Area Plan (BBAP) applies to about of state-owned uplands and lands beneath rivers and lakes in the Bristol Bay drainages, including lands at and in the vicinity of the proposed mine.

The Aspen anomaly is a seismic velocity anomaly in the mantle beneath central Colorado (in the region of Aspen, Colorado), which appears to reach down into the upper mantle. Helium with isotope ratios indicative of mantle origin emanates from the terrain above the anomaly. The Aspen anomaly coincides with the highest region of the Rocky Mountains (such as the San Juan Mountains and the Sawatch Range) and divergent drainages (Arkansas River, Colorado River and Gunnison River) which have cut deep gorges. This region underwent significant uplift during the Cenozoic starting from 10-5 million years ago and was subsequently eroded by the Colorado River.

The area is within the Ridge and Valley Subsection of the Northern Ridge and Valley Section in the Central Appalachian Broadleaf Coniferous Forest-Meadow Province. Yellow poplar, northern red oak, white oak, basswood, cucumber tree, white ash, eastern hemlock and red maple are found in colluvial drainages, toeslopes and along flood plains of small to medium-sized streams. White oak, northern red oak, and hickory dominate on the north and west, while chestnut oak, scarlet oak and yellow pine are found on ridgetops and exposed sites. The area includes the Lick Branch Barren special biological area and a Central Appalachian Shale Barren terrestrial community.

It also occurs in the northern part of the Black Sea basin from the Danube River to the Kuban River, and in the Caspian Sea in the River Volga and River Ural drainages. It is also introduced in a few different areas, but not to the extent of the pond loach (Misgurnus anguillicaudatus). Adult weatherfish live in dense patches of aquatic vegetation while juveniles prefer to live near the shoreline in very shallow water where there is a lot of detritus; neither adults nor juveniles are found in open areas without vegetation. Because of their habitat preferences, dredging and aquatic weed removal poses a danger to weatherfish populations.

The area is within the Ridge and Valley Subsection of the Northern Ridge and Valley Section in the Central Appalachian Broadleaf Coniferous Forest-Meadow Province. Yellow poplar, northern red oak, white oak, basswood, cucumber tree, white ash, eastern hemlock and red maple are found in colluvial drainages, toeslopes and along flood plains of small to medium-sized streams. White oak, northern red oak, and hickory dominate on the north and west, while chestnut oak, scarlet oak and yellow pine are found on ridgetops and exposed sites. There are about 39 acres of the Dragons Tooth Trail/McAffee Knob Special Biological Area on the southwest boundary.

The south side of Raritan Bay The Raritan River was perhaps the major drainage channel along the ice front throughout the Wisconsin glaciation (Stages 1, 2, 3 and 4). Prior to that time the region drained southward across the saddle between the Atlantic Highlands and the Newark Basin into the Delaware River Valley. This saddle area is a very broad flood plain that preserves river terrace gravels (Pensauken Formation) from the Sangemon Interglacial State (Stage 5), as well as older Pleistocene fluvial deposits (The Bridgetown Formation). During the lowstand in sea level caused by the Wisconsin glacier, the Raritan River carved back into its headlands and captured the major drainages from the Newark Basin.

The common dace is native to Europe and northern Asia where its occurs in the basins of the North Sea, Baltic Sea, White Sea and Barents Sea. It also occurs in the basin of the Caspian Sea and in the Black Sea basin it is found in the drainage systems of the Volga and Ural Rivers as well as in the Danube and the Dneiper. In France it occurs in the Seine River drainage and in the drainages of the Rhone and Arc which flow into the Mediterranean. In the Danube main river of Romania as well as in Scandinavia north of 69°N and most of central Finland this species has a localised distribution.

This may be a full-bench trail, where the treadway is only on the firm ground surface after the overlying soil is removed and sidecast (thrown to the side as waste), or a half-bench trail, where soil is removed and packed to the side so that the treadway is half on firm old ground and half on new packed fill. In areas near drainages, creeks and other waterways, excavation spoils are taken away in bulk and deposited in an environmentally benign area. In problem areas trails are established entirely on fill. In such cases the soil is packed down firmly and the site is periodically checked to maintain the stability of the trail.

The yellow-crowned elaenia (Myiopagis flavivertex) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in eastern Orinoco Basin Venezuela, the Guianas, and along the Amazon River corridor; also Colombia, Brazil, Guyana, Suriname, French Guiana, Ecuador and Peru. Yellow- crowned elaenia is found in the Amazon Basin along the major river course of the Amazon, also the outlet of the adjacent Tocantins River, then after an interruption in the range along the Amazon River, it is along Amazon drainages from eastern Peru, and Ecuador along the river corridors. It also ranges northeastwards into the Guyanas, avoiding the Guiana Shield, from the Amazon River outlet to the Atlantic.

The Mulato-Getudo Fault, in some parts called Jetudo Fault,Plancha 5-09, 2015 extends along the eastern foothills of the Central Ranges of the Colombian Andes, where it marks the abrupt break in slope of the east-tilted Tertiary erosion surface of the Cordillera and the flat alluvial plains of the Magdalena River in the Middle Magdalena Valley. The fault forms a regional- scale degraded fault escarpment with an outstanding break in slope. It offsets Pliocene to Quaternary deposits and an extensive tilted erosional surface of probable Miocene to Pliocene age (pre-Mesa Formation, older than 1.5 Ma). The northern half of the fault is characterised by aligned drainages and broad valleys.

The area is within the Ridge and Valley Subsection of the Northern Ridge and Valley Section in the Central Appalachian Broadleaf Coniferous Forest-Meadow Province. Yellow poplar, northern red oak, white oak, basswood, cucumber tree, white ash, eastern hemlock and red maple are found in colluvial drainages, toeslopes and along flood plains of small to medium-sized streams. White oak, northern red oak, and hickory dominate on the north and west, while chestnut oak, scarlet oak and yellow pine are found on ridgetops and midslopes on the south and east. Unusual flora and fauna found in the area include a globally rare shrub, the pirate bush; and an invertebrate the orangefin madtom.

During that summer there was also high predation of moose by grizzly bears in small patches of surviving timber. The winter following the fires many old moose died, probably as a combined result of the loss of good moose forage and a harsh winter. The fires forced some moose into poorer habitats, with the result that some almost doubled their home range, using deeper snow areas than previously, and sometimes browsing burned lodgepole pines. Moose are commonly observed in the park's southwestern corner along the Bechler and Fall rivers, in the riparian zones around Yellowstone Lake, in the Soda Butte Creek, Pelican Creek, Lewis River, and Gallatin River drainages, and in the Willow Park area between Mammoth and Norris.

It is the home of the White River First Nation. The First Nation is made up of Upper Tanana speaking people whose traditional territory extends from the Donjek River into neighboring Alaska, and Athapaskan Northern Tutchone speaking people whose traditional territories included the lower Stewart River and the area south of the Yukon River on the White and Donjek River drainages. In addition to the Alaska Highway, the community is served by the Beaver Creek Airport. The CBSA station is the furthest from the border crossing of any Canadian customs station at a distance of , and at least up to the 1990s, some individuals lived in the "no man's land" in between the border and customs.

Both drainages join the Los Angeles River north of downtown Los Angeles. It is built of the Angeles Crest, the San Rafeles, and the canyon in the middle La Cañada Flintridge varies in elevation from about 970 feet (295 m) just below Devil's Gate Dam in the Arroyo Seco to about 2400 feet (730 m) at the highest neighborhood, along the mountain front east of Pickens Canyon, at the upper end of Ocean View Blvd. The city limits extend into the San Gabriel Mountains and reach 3440 feet (1050 m) along Mount Lukens Road, which follows the crest line well above the developed city. In August 2009, the city came under threat by the Station Fire.

" In 2000 the focus of Living Landscapes was on the Upper Fraser Basin, a "vast area extending across most of south-central British Columbia including the Fraser River valley upstream from Big Bar Creek, as well as it is tributary drainages such as the Chilcotin, Quesnel, and Nechako Rivers." During 2001-2002 RBCM hosted five Upper Fraser Basin communities including, Valemount, British Columbia, Burns Lake, Williams Lake, Quesnel and Prince George attended by approximately 4,500 people. Visitors met and interacted with local Living Landscapes researchers and Victoria-based RBCM curators. The events featured exhibits from the RBCM's permanent collections as well as "illustrated talks and demonstrations on a variety of topics by local and museum experts.

Saline Wetlands Conservation Partnership (SWCP) is a conservation program devoted to the protection and preservation of Nebraska’s Eastern Saline Wetlands. The Eastern Saline Wetlands of Lancaster and Saunders counties Nebraska are among the most unusual and threatened wetland communities in the state. Limited to the floodplain swales and depressions within the Salt Creek, Little Salt Creek, and Rock Creek drainages, it’s estimated that the Eastern Saline Wetlands once covered an area in excess of . Today, due to extensive degradation, draining and filling through commercial, residential, and agricultural development, less than remain, and many of these remnants are highly degraded. Now more than ever it’s become increasingly important to preserve what remains of this unique wetland resource.

The Alabama shad (Alosa alabamae) is a species of clupeid fish endemic to the United States where it breeds in medium to large flowing rivers from the Mississippi River drainage to the Suwannee River, Florida, as well as some Gulf coast drainages. The biology and status of this fish is little known but it has become increasingly rare. The International Union for Conservation of Nature has rated it "data deficient" and the United States National Marine Fisheries Service has listed it as a Species of Concern. Reasons for its decline are thought mainly to be because of the many locks and dams blocking access for the fish to up-river spawning grounds.

The Piute Wash outfall down bajada/alluvial fan, after junction with Sacramento Wash; the downslope descends to the west side of the south-flowing Colorado River. The Sacramento Wash (California) is part of a 2-valley south-trending drainage system, shaped like a U; Piute Wash is the eastern part of the drainage; the Sacaramento Wash is the western. The Sacramento Wash turns eastward, combines with other bajada drainages from the west and south, and merges with the Piute Wash, to rapidly descend down from the foothills of the Dead Mountains to the western bank of the Colorado River. The approximate center of the Sacramento Wash drainage is the center of Lanfair Valley, the Lanfair Buttes.

Hence, E. driftwoodensis is an archaic salmonid, representing an important stage in salmonid evolution. A gap appears in the salmonine fossil record after E. driftwoodensis until about seven million years ago (mya), in the late Miocene, when trout-like fossils appear in Idaho, in the Clarkia Lake beds. Several of these species appear to be Oncorhynchus—the current genus for Pacific salmon and some trout. The presence of these species so far inland established that Oncorhynchus was not only present in the Pacific drainages before the beginning of the Pliocene (~5–6 mya), but also that rainbow and cutthroat trout, and Pacific salmon lineages had diverged before the beginning of the Pliocene.

Joseph Reddeford Walker was one of the most prominent of the explorers, and charted many new paths through the West, which often were then utilized by emigrants crossing to settle in Western towns and communities. In 1833, his exploring party discovered a route along the Humboldt River across present-day Nevada, ascending the Sierra Nevada following the Carson River and descending via Stanislaus River drainages to Monterey. His return route across the southern Sierra was via Walker Pass, named after Walker by John Charles Fremont. The approach of the Sierra via the Carson River route later became known as the California Trail, the primary route for the emigrants to the gold fields during the California gold rush.

Nothobranchius kirki, the redfin notho, is a species of killifish from the family Nothobranchiidae which is endemic to Malawi where it occurs in the drainages of Lake Malawi and Lake Chilwa. It inhabits swamps and ephemeral pools. This species can reach a length of TL. It can also be found in the aquarium trade. This species was described in 1969 by the South African ichthyologist Rex Jubb from types collected by R. G. Kirk, who was a fish biologist of the Agricultural Research Services part of the Ministry of Natural Resources of Malawi, from a pool adjacent to the Likangala River which forms part of the endorheic basin of Lake Chilwa in Malawi.

The Skunk River rises in the northeast part of the county, and flows west-southwest through the lower central part of the county, discharging into the Platte southeast of Little Falls. The terrain consists of low rolling hills, partly wooded, carved with drainages and gullies, and with all available area devoted to agriculture.Morrison County MN Google Maps (accessed 3 May 2019) It generally slopes to the south, and slopes to the river valley from both east and west borders, with its highest point on the Camp Ripley Military Reservation, 2.4 miles (3.9 km) east and 1.4 mile (2.2 km) north of the east end of Lake Alexander, at 1,521' (463m) ASL.Morrison County High Point, Minnesota.

Morgan County is where the glaciers stopped their southward advance during the last ice age. As a result, the area has both flat areas and rolling hills, with the most diverse soil of any county in the United States.History and Heritage (Visit Morgan County - accessed 6 August 2020) The extensive woodlands of the eighteenth century have been cleared on the county's flat areas, with agricultural or urban uses dominating. The county is significantly carved with wooded drainages, leading to the southwest-flowing White River.Morgan County IN (Google Maps, accessed 6 August 2020) According to radar telemetry gathered by the US Shuttle Radar Topographic Mission, Morgan County terrain ranges from 604 feet/184 meters to 1010 feet/308 meters ASL.

Elliptio dilatata, museum specimen from the Ohio river, Illinois, US Another Elliptio dilatata museum specimen Elliptio is a genus of medium- to large- sized freshwater mussels, aquatic bivalve mollusks in the family Unionidae, commonly known as the unionids, freshwater mussels or naiads. In contrast with many other groups of American Unionidae, the Elliptio species reach their greatest diversity in the Atlantic-draining rivers of Georgia and the Carolinas, and large parts of Florida. One species ranges north into New England and southern Canada, and two occur in the interior Mississippi drainages. Most Elliptio species have elongated shells, with silvery or purplish interior nacre beneath a thick periostracum, and few reach large size or thickness.

The Treaty of 1818 saw expansion of both British North America and the US, where the boundary extended westward along the 49th parallel, from the Northwest Angle at Lake of the Woods to the Rocky Mountains. The treaty extinguished British claims to the south of that line up to the Red River Valley, which was part of Rupert's Land. The treaty also extinguished U.S. claims to land north of that line in the watershed of the Missouri River, which was part of the Louisiana Purchase. This amounted to three small areas, consisting of the northern part of the drainages of the Milk River (today in southern Alberta and southwestern Saskatchewan), the Poplar River (Saskatchewan), and Big Muddy Creek (Saskatchewan).

This source is located in the northernmost corner of Frankford Township, approximately west of the hamlet of Beemerville in Wantage Township.Rollin D. Salisbury, The Glacial Geology of New Jersey: Volume V of the Final Report of the State Geologist (Trenton, NJ: MacCrellish & Quigley, 1902), 375ff. Retrieved October 17, 2015. From the source, the Papakating flows southeast through Frankford Township north of the borough of Branchville. In this region, the Papakating is separated from the watershed of the southward-flowing Dry Brook, a tributary of the Paulins Kill, by approximately 500 feet. The two watersheds are divided by a small rise in elevation of 20–30 feet between the drainages the two streams.

Summit Lake is the name of an unincorporated community in the Central Interior of British Columbia, Canada, located north of the City of Prince George on the John Hart Highway at the lake of the same name. The community of McLeod Lake (Fort McLeod) is a few miles farther to the north. Summit Lake is situated at the divide between the Fraser and Peace) and so is at the divide between the Pacific and Arctic drainages. As such, it is also the location of the prominence col for Mount Orizaba, in relation to Denali, meaning also that it is one of the lowest locations along the Continental Divide of North America north of Mexico (elevation 710 m (2329 ft).

The Whitehorse Basin cutthroat trout refers to a population segment of the cutthroat trout complex (Oncorhynchus clarkii) from the streams of the Whitehorse Basin (or the Coyote Basin), southeastern Oregon. It is alternatively considered as a part of the Lahontan cutthroat trout subspecies (Oncorhynchus clarkii henshawi),Species Fact Sheet: Lahontan cutthroat trout, U.S. Fish & Wildlife Service or of the Humboldt cutthroat trout (O. c. humboldtensis) whose main range is in Nevada.Patrick C. Trotter and Robert J. Behnke (2008) The Case for Humboldtensis: A Subspecies Name for the Indigenous Cutthroat Trout (Oncorhynchus clarkii) of the Humboldt River, Upper Quinn River, and Coyote Basin Drainages, Nevada and Oregon Western North American Naturalist, 68(1):58-65.

The fish species, Etheostoma microperca, is distributed across the northeastern part of the United States, particularly in the midwest. This fish is also one of the 324 fish species found in Tennessee, and has been found in other states, such as Minnesota, Illinois, and Ohio, and many others. As of 2008, it had been documented at a limited number of sites across the southern two-thirds of Minnesota, but most of its populations occurred in the west-central portion of the state in the Otter Tail River and upper Mississippi River drainages. Adults of E. microperca are usually found in streams near vegetation, such as along overhanging grassy banks and among filamentous algae.

Bull Run Lake, Carson–Iceberg Wilderness. The Carson–Iceberg Wilderness supports a native population of the only Paiute cutthroat trout in existence in the drainages of Silver King Creek, a tributary of the East Fork Carson River. They were listed as endangered under the Endangered Species Preservation Act of 1966 and upgraded to threatened status in 1973 with the passage of the Endangered Species Act (ESA) which allowed regulated fishing of the Paiute. Historically, the US Fish and Wildlife Service believe the Paiute trout only occupied the Silver King Creek and its tributaries below the barrier of LLewellyn Falls, and around 1912 were introduced to other streams where the Paiute hybridized with the Lahonton and rainbow trout species.

Such would imply that Soda Lake and Silver Lake during the Blackwelder stand were connected with Lake Manly; this theory is known as "mega Lake Manly". Such an expansion would have occurred whenever the lake levels rose above above sea level and thus could flow south across Salt Spring Hills; the enlargement of the lake surface that resulted would have increased evaporation and stabilized lake levels. There is no clear cut evidence that these shorelines are of the same age as the Blackwelder shoreline, although they are of similar appearance. The spread of pupfish between the Mojave River and Death Valley drainages would also be more likely with such a lake configuration.

Originally, the Georgetown Divide Public Utility District (GDPUD) had obtained appropriative water rights from the State Water Resources Control Board. Also, GDPUD exercised pre-1914 rights for diversion of water from several tributaries of Pilot Creek in the South Fork American River. The Georgetown Divide Water Company and other water companies invested that included Sierra Pacific Power Company, Loon Lake Water and Power Company, California Water Company and the Pilot Creek Water Company claimed pre-1914 rights in the South Fork Rubicon and Pilot Creek drainages for years prior to the 20th century. These rights included storage in Loon Lake, diversion from South Fork Rubicon River, Gerle Creek and Pilot Creek and all its tributaries.

These uniform weaknesses are key to identifying rock slides because unlike slumps, flows, or falls, the failed material moves in a fairly uniform direction over a layer of solid, pre-existing rock. Rock may break down while falling during rockslides. The sudden, rapid release of material found in rock slides combined with the sheer size and weight of the material that is falling is what gives these events the potential to have devastating effects on human life and infrastructure. Rock slides are very common in the over steepened canyons and drainages of Idaho, particularly in those areas like the Salmon River Canyon where more than 5,000 feet of elevation may exist between the ridge tops and the canyon bottoms.

Poropuntius deauratus is a species of ray-finned fish in the genus Poropuntius which is found in coastal river drainages in central Vietnam: between the Thu Bon River in Quang Nam Province and the Quang Tri River in Quang Tri Province. There was a marked decline in this species' abundance between 2-000 and 2009 when the population may have declined by as much as 80%, this decline was probably caused by overfishing. Its habitat is medium and small sized rivers and streams where it is normally found in fast-flowing, clear water and it cannot survive where these are impounded. It diet mainly consists of fine debris, algae, diatoms, and aquatic insects.

The last of these glaciers existed until about 10,000 years ago, with their end points marked hummocks of debris. The glaciers formed glacial troughs, deposited moraines, and moved sand and gravel along with volcanic ash and cinders to cover the Metolius Valley floor. Black Butte lies about east–southeast of Suttle Lake, which occupies one of the local glacial troughs. Eruptions from Black Butte buried the ancestral Metolius River and left boulders of lava in the area, and Black Butte's formation dammed drainages for the Metolius, dividing the Metolius Valley into the northern segment where the river now runs and a southern portion that includes Black Butte Swamp, Glaze Meadow, and Indian Ford Creek.

Bright Star Wilderness is a wilderness area in Kern County in the U.S. state of California. The California Desert Protection Act of 1994 (Public Law 103-433) added the wilderness to the National Wilderness Preservation System and it is administered by the Bureau of Land Management (BLM). Bright Star Wilderness surrounds Kern County's Kelso Peak and drainages to the north, south and east, including Bright Star Canyon and Cortez Canyon. The Wilderness lies within the BLM’s Jawbone-Butterbredt Area of Critical Environmental Concern in the higher Mojave Desert and protects much of the Piute Mountains, of the southern Sierra Nevada (not to be confused with the Piute Mountains to east in Mojave National Preserve).

In January, 2007 Senate Bill 67, introduced by Senator Gary Stevens, of Kodiak, proposed the establishment of a State Fish and Game Refuge covering about of state land in the Kvichak and Nushagak drainages (with the refuge to be named after former Alaska Governor Jay Hammond). It proposed that no uses incompatible with: fish and wildlife populations; commercial or subsistence food gathering; or recreation would be allowed in the refuge. The bill sought to close the refuge to new mining claims. Most significantly, the bill would have made illegal the storage or disposal of any quantity of, "industrial waste," thereby making it impossible to develop any industry, including mines, within the refuge.

The area is within the Ridge and Valley Subsection of the Northern Ridge and Valley Section in the Central Appalachian Broadleaf Coniferous Forest-Meadow Province. Yellow poplar, northern red oak, white oak, basswood, cucumber tree, white ash, eastern hemlock and red maple are found in colluvial drainages, toeslopes and along flood plains of small to medium-sized streams. White oak, northern red oak, and hickory dominate on the north and west, while chestnut oak, scarlet oak and yellow pine are found on ridgetops and exposed sites. The area includes the Patterson Creek Barren special biological area as well as part of the County Line Barrens special biological area near the junction of Little Patterson Creek and Craig Creek.

The major drainages tributary to the Occoquan Reservoir can be divided into two principal sub-basins: Bull Run and Occoquan Creek. Despite being a major fresh water source, Occoquan Reservoir is listed on Virginia's Dirty Water List, with recorded high levels of phosphorus, turbidity, low dissolved oxygen, the presence of copper sulfate and the growing presence of pharmaceuticals, largely due to human land uses, population pressure and poor management. In 1968, the Virginia State Water Control Board (SWCB) commissioned a study of the Occoquan Reservoir and its tributary streams to draw up a plan of sustainable management for the reservoir. A 1970 analysis stated that the reservoir was "highly eutrophic...", and further, that "the sewage plant effluents are mainly responsible for the advanced stage of eutrophication occurring...".

The wilderness contains colluvial drainages, toeslopesDefined Term: Toeslope definitions - Defined Term, accessdate: July 15, 2017 and alluvial floodplains providing a rich environment that supports yellow poplar, northern red oak, white oak, basswood, cucumber tree, white ash, eastern hemlock, white pine and red maple. In the remaining land, white oak, northern red oak, and hickory are found to the north and west while chestnut oak, scarlet oak and yellow pine are found on ridgetops and slopes to the east and south. The area is one of the few sites in Virginia with table mountain pine and box huckleberry, species requiring fire to reproduce, and therefore becoming uncommon because of fire exclusion. The 20-acre Brush Mountain Special Biological Area is located on the crest of the mountain.

The Suárez Fault runs from Barbosa in the south,Mapa Geológico Santander, 1999 where it displaces the Simití Formation,Plancha 170, 2009 and joins the Bucaramanga Fault a few kilometers to the north of the city of Bucaramanga. The Suárez Fault cuts Jurassic (Girón Formation),Plancha 135, 2009 and Cretaceous sedimentary rocks (Simití, Rosablanca and Paja Formations),Plancha 151, 2009 and Quaternary alluvial deposits and mud flows that form the "Bucaramanga Terrace".Plancha 120, 2010 The trace of the fault is well defined, controls linear drainages such as the Suárez River for several kilometers, has sag ponds, and locally dams alluvium. The fault vertically offsets debris flows in the area of Girón and La Fuente and displaces a Tertiary erosion surface.

Crawfish Valley, a wildland in the George Washington and Jefferson National Forests of western Virginia, has been recognized by the Wilderness Society as a special place worthy of protection from logging and road construction. The Wilderness Society has designated the area as a “Mountain Treasure”. The Forest Service refers to this area as “Bear Creek”, but the Wilderness Society prefers the name “Crawfish Valley” because the valley is larger and serves as a divide between Reed and Bear Creeks, two of the principal drainages in the area. The largest inventoried roadlesss area in the Jefferson Forest, the immense area includes a section of the Appalachian Trail and 24 miles of other trails making the area popular with hikers and horseback riders.

This wide, gentle, marshy pass separates the headwaters of Pacific Creek, which flows Westerly to the Pacific Ocean via the Snake and Columbia Rivers, and Atlantic Creek, which flows Easterly to the Atlantic Ocean via the Yellowstone, Missouri and Mississippi Rivers. At Two Ocean Pass, exactly on the Continental Divide, North Two Ocean Creek flows down from its drainage on the side of Two Ocean Plateau and divides its waters between Pacific Creek and Atlantic Creek. This spot is known as Parting of the Waters, and occurs at 44° 02.576'N, 110° 10.497'W. At this exact spot, water actually covers the Continental Divide such that a fish could safely swim from the Pacific Ocean to the Atlantic Ocean drainages.

They tend to occupy pure coniferous forest only near edges or when clearings and glades exist. Often areas in the conifer forest, especially the taiga in the north, where the tawnys will occur show a mixture of some deciduous tree growth such as birches and poplars. In the taiga-dominant environments of vast Russia, tawny owls are usually restricted to broadleaf stands often in river drainages, parks, orchards and cultivated lands, often where woods of Quercus, Tilia and Betula stand with plentiful broken snags and dead trees. Locally, the tawny owl has been known to be adaptive to subalpine forest dominated by conifers, such as the pine forests in the Spanish ranges of Sierra de Gredos and Sierra de Guadarrama.

Yellow poplar, northern red oak, white oak, basswood, cucumber tree, white ash, eastern hemlock and red maple are found in colluvial drainages, toeslopes and along flood plains of small to medium-sized streams. White oak, northern red oak, and hickory dominate on the north and west, while chestnut oak, scarlet oak and yellow pine are found on ridgetops and midslopes on the east. Wild natural trout streams in Virginia are classified by the Department of Game and Inland Fisheries by their water quality, with class i the highest and class iv the lowest.9VAC25-260-370.

View of the Basturs Lake The Basturs Lakes are part of the Isona Tufa Mound Complex developed within the Tremp Basin, an artesian structural basin that forms part of the south-central Pyrenean piggy- back thrust located in the Spanish Pyrenees. The Isona Tufa Mound Complex, located in the discharge zone of the confined artesian aquifer, is a unique geological formation in Europe including eleven subcircular depressions associated with tufa mounds and related to former groundwater outlets. These peculiar crater-like features consist of a central depression filled with lake deposits and enclosed by an annular more resistant tufaceous rimstone. The tufa complex developed in association with non-thermal artesian springs of calcium-bicarbonate-rich waters, perched above the local drainages.

The Peacock Mountains, are a smaller, lower elevation range, only about 10-mi (16 km) wide. Peacock Peak (Arizona), is the range highpoint, in the approximate center of the range, with a ridgeline north to the range terminus (13-mi). At the north terminus, Arizona State Route 66 transits northeast to southeast around the range; the Grand Wash Cliffs lie due north; the northwest-trending Hualapai Valley extends from the terminus, and the Grand Wash Cliffs form its east border, also forming the southwest border of the Music Mountains; the cliffs extend approximately 100-mi northwards approaching southwest Utah. The east side of the Peacock Mountains are defined by due-north and due-south flowing drainages on the west of the Cottonwood Cliffs.

Evidence suggests that the westslope cutthroat trout was able to establish populations east of the divide via Summit Lake at Marias Pass which at one time connected the Flathead River drainage with the upper Missouri River drainage. Scientists speculate that there are several mountain passes associated with the headwaters of the Colorado River drainage and Arkansas/Platte River drainages that would have allowed migration of cutthroat trout east of the divide. Cutthroat trout have been introduced into non-native waters outside their historic native range, but not to the extent of the rainbow trout . Within the native range of the Yellowstone cutthroat trout, U.S. Fisheries Bureau and National Park Service authorities introduced Yellowstone cutthroat trout into many fishless lakes in Yellowstone National Park.

Colonel Miles, leading elements of the 5th and 22nd infantry, avoided an ambush by Oglala Sioux under Crazy Horse, and segments of Cheyenne under White Bull and Two Moons, and then engaged the Indian forces driving them back up the Tongue River., Chapter 7 The battle is officially referred to as the Battle of the Wolf Mountains, although this is a misnomer. The battle is also referred to by various other names, including the Battle of Pyramid Butte, the Battle of the Butte, and Miles Battle on the Tongue River. The Wolf Mountains are actually several drainages to the west from the battle site, but General Miles' report stated the battle was in the Wolf Mountains, and that name has stuck.

Although the plains topminnow is not considered a federally threatened, endangered, or sensitive species and has a Global Heritage Status Rank of G4 (apparently secure) from the Nature Conservancy, there has been a declining trend in the distribution of the plains topminnow, particularly in the Platte and Republican River Drainages. Currently, the plains topminnow are found in only 34.4% of sites that have historically been inhabited by the plains topminnow. In Minnesota, the plains topminnow is present in all historical locations, however, abundance is lower than normal at 69.2% compared to past collections. The primary threats to the plains topminnow are physical or chemical habitat degradation, stream fragmentation, introduction of nonnative fishes, reservoir creations, sewage discharge, feedlot runoff, intense livestock grazing and pumping of saline groundwater.

Map of Vigo County To the north of Vigo County, the Wabash River defines the boundary between Vermillion and Parke counties; the river then enters Vigo County and winds to the south-southwest, defining the southern portion of the county's western border with Illinois before continuing south along Sullivan County's western border. Vigo County is thus the southernmost county in Indiana on the right bank of the Wabash. The county's low hills are devoted to agriculture or urban development; only the drainages and river-adjacent areas are still wooded.Vigo County IN (Google Maps, accessed 19 September 2020) Its highest point (680 feet/207 meters ASL) is Sanford Hill, one mile (1.6 km) west of Paint Mill Lake, south of Terre Haute.

Proceeding sometimes on foot, sometimes by raft, Black and a smaller crew explored the region of the Spatsizi Plateau, there finding one of the sources of the Stikine River and so reaching the boundary between the Arctic and Pacific drainages. Journeying north-eastward, Black crossed another divide — this time between the Stikine and Liard Rivers — and rafted some way down the Kechika by way of its tributary, the Turnagain River, before returning again down the Finlay. Black's vivid journal account of the expedition conveys the extreme hardships faced by the crew, and what Black believed was the general privation of the country — both as a source of food and of furs. Two of his men deserted in the course of the expedition, giving Deserters Canyon its name.

Distribution map of Galaxias oliros, the obscure galaxias The obscure galaxias is found at a wide range of elevations from in the Murray river system in Victoria and southern New South Wales as well as south of the Great Dividing Range in western Victoria including all tributaries to the Wimmera River and several tributaries to the Murray River within the Mount Lofty Ranges in South Australia. The fish is also recorded from coastal drainages in western Victoria including the Corangamite Basin, the Hopkins River and extending through to Mosquito Creek within the Bool Lagoon catchment in South Australia. Additionally, the fish is found very close to the sea in the Merri River and the Darlot/Fitzroy River systems in western Victoria.

The upper Carson River watershed provides habitat for the threatened Lahontan cutthroat trout (Oncorhynchus clarki henshawi), as well as large non-native rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta), providing excellent fly fishing. The Lahontan cutthroat is threatened by hybridization with rainbow trout, but there is a pure Lahontan strain on of the East Fork Carson River from the headwaters to Carson Falls. There is also a native population of the only Paiute cutthroat trout (Oncorhynchus clarki seleniris) in existence in the drainages of Silver King Creek, a tributary of the East Fork Carson River in the Carson Ranger District of the Humboldt-Toiyabe National Forest. North American beaver (Castor canadensis) were re-introduced to the Carson River watershed around 1940 and have thrived since.

The majority of the reddish hermit's range, in northern and central South America, is the entire Amazon Basin to the foothill drainages of the eastern Andes slope. The Caribbean and Atlantic coasts of the entire Guianas are included in the northeast; in the southeast, the southeastern limit is the eastern banks of the Tocantins River in the Araguaia-Tocantins River system, usually included as part of the Amazon Basin. The countries included in the bird's range in the western Amazon Basin drainage are Colombia, Ecuador, Peru, and Bolivia. Besides the reddish hermit's range in the Amazon Basin, to the northwest it is found in southern and eastern Venezuela adjacent to the Guianas; this is most of the eastern portions of Venezuela's Orinoco River drainage.

The zander is host to a large number parasites among which is the nematode Anisakis which infects their gastro-intestinal tract and which can infect humans if the fish is smoked, fried or otherwise cooked at temperatures lower than . There are a large number of known parasites of the zander which affect the skin, eyes and internal organs. The zander is known to be a vector of the trematode Bucephalus polymorphus which it may pass to native cyrinids and this may have resulted in decreases in the populations of these fishes in some French river systems during the 1960s and 1970s. More recently the primary host of B. polymorphus, the zebra mussel (Dreissena polymorpha) has invaded many drainages in Europe.

The blackish-grey antshrike is found in Brazil's southeastern Amazon Basin as well as along the Amazon River proper, and northwards at the Amazon's outlet, into the extreme eastern areas of French Guiana with Brazil's northeast state of Amapá. The southeast range extends slightly southwestward into that quadrant, about 1000–1400 km, and its eastern limit is the final 950 km of the Tocantins River drainage. On the west bordering some of the southwest quadrant, the range is limited by the Madeira River and continues upstream into extreme northeast Bolivia for 75 km in an area around the Madeira and Guaporé River confluence. To the east the range is contiguous and covers the river drainages of the Tapajós, Xingu River, and lower Tocantins River, a range of about 3500 km.

Caloocan City has surface waters that either have natural course (creeks and rivers) or constructed to serve as drainages to remove excess water from soil surfaces. South Caloocan has about a total of 5.0 km length of open drainage canals that serve mainly the reclamation area comprising Kaunlaran Village (Dagat-Dagatan Development Project) and nearly 11.3 km length of natural surface water coursing through the different natural river systems. These include the Tinajeros-Tullahan River along the Caloocan-Valenzuela boundary; Maligaya Creek within La Loma Cemetery and crossing Rizal Avenue Extension; Casili Creek which terminates in Estero de Maypajo, and Cantarilla/Panaca creek along the Caloocan-Malabon boundary. In North Caloocan, all surface waters consist of natural streams, the longest being the Meycauayan-Marilao River dividing Caloocan and Bulacan.

Washo Laurie Bauer, 2007, The Linguistics Student's Handbook, Edinburgh (or Washoe; endonym ) is an endangered Native American language isolate spoken by the Washo on the California–Nevada border in the drainages of the Truckee and Carson Rivers, especially around Lake Tahoe. While there are only 20 elderly native speakers of Washo,Victor Golla (2011) California Indian Languages since 1994 there has been a small immersion school that has produced a number of moderately fluent younger speakers. The immersion school has since closed its doors and the language program now operates through the Cultural Resource Department for the Washoe Tribe. The language is still very much endangered; however, there has been a renaissance in the language revitalization movement as many of the students who attended the original immersion school have become teachers.

Portions of these canal systems are literally "hung" on the edges of steep sided, gently sloping mesas formed from remnant Quaternary age bajadas.Lindsey, D.A., and Van Gosen, B.S., 2010, Processes of terrace formation on the Piedmont of the Santa Cruz River valley during Quaternary time, Green Valley-Tubac area, southeastern Arizona: U.S. Geological Survey Scientific Investigations Report 2010–5028, 39 p. The canals appear to be distinct from those found in the vicinity of Phoenix and elsewhere in the Southwest in that they obtained their water from mountain drainages fed by runoff, springs, and artesian sources, rather than from rivers. They are also unusual in that they traverse the vertically undulating to severely erratic uplands of basin and range topography rather than being restricted to a nearly level riverine floodplain.

In fact, it is thought that this was the pass that provided the route for Yellowstone cutthroat trout to migrate from the Snake River (Pacific) to Yellowstone River (Atlantic) drainages. This site received designation as a National Natural Landmark in 1965, bearing the official name of Two Ocean Pass National Natural Landmark. However, Parting of the Waters, by which this site is more commonly known, is actually about northwest of the low point of Two Ocean Pass, where North Two Ocean Creek emerges from its drainage basin on the side of Two Ocean Plateau. Inasmuch as North Two Ocean Creek splits into streams which flow separately to the Atlantic and Pacific Oceans, the entire drainage of North Two Ocean Creek lies within an area that makes up the "Continental Divide" at this place.

The village of Livermore was benchmarked with an elevation of , a quarter mile from the eastern boundary adjoining Hart's Location. Livermore is a long, relatively narrow township, forming a very rough approximation of a crescent with its endpoints at the north and west. Livermore and its neighbor to the west, Lincoln, occupy a large area of uninhabited woodland once known as the "Pemigewasset Wilderness" (a portion of which is preserved in the present-day WMNF Pemigewasset Wilderness in Lincoln). The original boundary between the two towns did not follow natural features, such as the crest of the divide that separates the Pemigewasset River and Saco River drainages, which led to numerous charges and countercharges of cutting over the line between the two owners, the Saunders family in Livermore and James Everell Henry in Lincoln.

The range of B. ambusticauda is listed as including the Chao Phraya and Mae Klong drainages in Thailand; the original distribution of this species included the Chao Phraya River drainage from Bangkok upriver to the lower Nan River. It has also been reported in the Mekong Basin in Vietnam, Cambodia and Laos from the Tonlé Sap lake to the lower Nam Ngum River, but confirmed records from this basin are lacking and this is not recognized as part of its range by the IUCN. Previous records of B. melanopterus from the same rivers is due to confusion with B. ambusticauda; B. melanopterus only occurs in the Malay Peninsula, Sumatra, and Borneo. Large numbers of B. melanopterus are exported for the aquarium trade from Thailand, but these are all captive bred.

The chub is distributed throughout most of northern Eurasia, it can be found in the rivers flowing into the North, Baltic, northern Black, White, Barents and Caspian Sea basins, the Atlantic basins south to Adour drainage in France and in Great Britain north to 56 °C, in Scandinavia in southern Finland and southern Sweden north to around Stockholm. In the Mediterranean basin it is found in France from the Var to the Hérault, and may also be present in the Aude, drainages. It is absent as a native species from Ireland and Italy but has been introduced to both countries; in Italy S. cephalus is present and acclimatised since decades, but it seems marginally found here and there (mainly in the Po river basin), never forming well established populations.

Soils of Padua area Soils of St. John's University area Stearns County abuts nine counties; no Minnesota county touches a greater number. The Mississippi River flows southeast along its northeast border, and the Sauk River drains the central part of the county into the Mississippi at St. Cloud. The county terrain consists of low rolling hills, lightly wooded, dotted with lakes and ponds, and carved with drainages. All available area is devoted to agriculture or has been developed.Stearns County MN Google Maps (accessed 3 May 2019) The terrain slopes to the east and south,"Find an Altitude/Stearns County MN" Google Maps (accessed 3 May 2019) with its highest point a local protuberance at 7.6 miles (12.2 km) west and 1.6 mile (2.6 km) south of St. Joseph, at 1,461' (445m) ASL.

In the 1980s the focus shifted somewhat to electrofishing, which temporarily stuns fish so they can be captured and examined. Fish showing more evidence of hybridization are removed to other drainages, while relatively pure Paiute cutthroats are returned to the water unharmed. Angling is prohibited in most streams where Paiute cutthroats predominate, however future plans include downstream expansion of Paiute cutthroat range by removing other trout and installing barriers. Although restoration plans were delayed by lawsuits concerned about the impact of rotenone on other stream inhabitants, the U.S. Fish & Wildlife Service decided in May, 2010 to proceed with poisoning to eradicate non-native and hybrid trout in Silver King Creek from Llewellyn Falls downstream to the confluence with Snodgrass Creek and associated tributaries; and to restore Paiute cutthroat trout to its historical range through stocking.

Olallie Butte is located within Jefferson, Marion, and Wasco counties, all within the northwestern to north-central part of the U.S. state of Oregon. The volcano lies just outside the irregularly shaped Olallie Roadless Area, which lies within the Mount Hood National Forest to the west of the major crest of the Cascade Range and directly north of the Mount Jefferson Wilderness. This region encompasses of an upland area with small volcanoes, bordered to the southwest by the canyon wall of the North Fork of the Breitenbush River. It can be accessed from trails running from the Clackamas and Breitenbush River drainages, which reach the eastern and southern parts of the Olallie Area, as well as logging roads that enter the Olallie roadless area at its northern portion.

Although most of his conclusions about sites visited by Father Eusebio Kino have been discredited, Di Peso is recognized as a true scholar and he did define the first archaeological Sobaipuri site, making key contributions to the field, some of which are only recently being recognized. The other sites he thought might be Sobaipuri turned out to be late prehistoric sites representing Puebloan and other culture groups or the remnants of a later Spanish fort Santa Cruz de Terrenate. Archaeologist Deni Seymour has studied the Sobaipuri for 30 years, revisiting some of the issues raised by Di Peso. On the San Pedro, Santa Cruz, and tributary drainages of Sonoita creek, Babocomari, and Aravaipi Seymour has documented more than 80 archaeological sites occupied by the Sobaipuri (Seymour 1989, 1990, 1993a).

Research from the late 1800s to the 1980s suggests a trend of intentional stockings of non- indigenous fish into ponds, lakes and rivers in the United States. At that time, little was known about environmental impacts, or long-term effects of new species establishment and spread as a result of "fish rescue and transfer" efforts, or the importance of nongame fish to the ecological balance of aquatic ecosystems. Introductions of bowfin to areas they were considered a non-indigenous species included various lakes, rivers and drainages in Connecticut, Illinois, Iowa, Kansas, Kentucky Maryland, Massachusetts, Missouri, New Jersey, New York, North Carolina, Pennsylvania, Virginia, West Virginia, and Wisconsin. Many of the introductions were intentional stockings by various resource management; however, there is no way to positively determine distribution resulting from flood transfers, or other inadvertent migrations.

The eastern drainage divide of the Sweetwater watershed lies on the main divide of the Cuyamacas, which also separates streams of the Pacific slope from streams draining to the endorheic basin of the Salton Sea farther to the east. To the north, the Sweetwater basin shares borders with those of the San Diego River and the smaller streams that drain portions of National City and San Diego. On the south, it is bordered by the Otay River and Tijuana River drainages – specifically for the Tijuana, the subwatershed of Cottonwood Creek, the river's main tributary in the U.S. Before reaching San Diego Bay, the river flows into Sweetwater Marsh, a part of the San Diego National Wildlife Refuge. Adjacent to the marsh is the Chula Vista Nature Center hosting nature walks and an aviary with native birds such as burrowing owls, egrets and herons.

Carpenter Lake, officially Carpenter Lake Reservoir, is the largest of the three reservoirs of the Bridge River Power Project, which is located in the mountains west of Lillooet, British Columbia. The lake is about 185 kilometres north of the province's major city of Vancouver and is formed by the 1951 diversion of the Bridge River by Terzaghi Dam into Seton Lake via a tunnel through Mission Mountain, which separates the Seton and Bridge drainages. Several ranches and homesteads in the broad serpentine of the upper Bridge River basin were flooded out by the hydro project, which changed the character of the upper valley forever. Carpenter Lake is about 50 kilometres in length, although its upper reaches beyond the flooded gold mining town of Minto City are usually mudflat due to fluctuations in the level of the reservoir.

Almon Harris Thompson (September 24, 1839 – July 31, 1906), also known as A. H. Thompson, was an American topographer, geologist, explorer, educator and Civil War veteran. Often called "The Professor" or simply "Prof", Thompson is perhaps best known for being second in command of John Wesley Powell's Second Geographical Expedition (1871–1875), a federally funded scientific expedition that retraced the route of Powell's original expedition in order to further explore and map the drainages and canyons of the Green and Colorado Rivers in what is now southern Utah and northern Arizona. Thompson's diary of the expedition was originally published in the Utah Historical Quarterly in 1939. Through his work on the Powell expeditions and later as a geographer at the U.S. Geological Survey, he was responsible for naming many geographic locations in the Western United States.

The Kaweah River is a river draining the southern Sierra Nevada in Tulare County, California in the United States. Fed primarily by high elevation snowmelt along the Great Western Divide, the Kaweah begins as four forks in Sequoia National Park, where the watershed is noted for its alpine scenery and its dense concentrations of giant sequoias, the largest trees on Earth. It then flows in a southwest direction to Lake Kaweah – the only major reservoir on the river – and into the San Joaquin Valley, where it diverges into multiple channels across an alluvial plain around Visalia. With its Middle Fork headwaters starting at almost above sea level, the river has a vertical drop of nearly on its short run to the San Joaquin Valley, making it one of the steepest river drainages in the United States.

Historically, Waddell Creek was home to spawning runs by both steelhead trout (Oncorhynchus mykiss) and coho salmon (Oncorhynchus kisutch). In 1995 a review of coho south of San Francisco Bay found coho restricted to only one remnant population in Waddell Creek, one small naturalized (hatchery-influenced) population in Scott Creek and a small hatchery-maintained, non-native run in the San Lorenzo River, all in Santa Cruz County. Historically, coho were found in approximately 50 coastal drainages in San Mateo and Santa Cruz counties, but by the 1960s spawning runs were limited to 11 stream systems. The 1995 combined average annual spawning population of native and naturalized coho salmon in Waddell and Scott Creeks was estimated at only 50-60 adults, comprising only 1.5% of the estimated abundance of coho salmon south of San Francisco Bay in the early 1960s.

With elevations ranging from 2000 feet in the lower drainages to 3600 feet on the ridge crest, London Bridge Branch wild area is dominated by a mountain ridge with small, steep sideslopes. A diversity of geologic features is characteristic of the Southern Appalachian Mountains. Geologic rock types are the Erwin Formation with white, vitreous quartzite, interbeds of dark-green, silty and sandy shale, minor siltstones and very fine sandstone; the Hampton Formation with dark greenish-gray, silty and sandy shale, micaceous shale, numerous layers of medium-grained, feldspathic, and thinly bedded sandstone; the Union Formation, a sequence of grey feldspathic sandstone, arkose, conglomerate, greywacke, siltstone and shale, and greenish amygdaloidal basalt flow; and Shady Dolomite, a light gray, well-bedded dolomite with thin to medium-bedded gray limestone, and yellowish brown residual clays with “jasperoid” diagnostic.

The gregarious slender salamander is endemic to the western slopes of the southern and central Sierra Nevada in California, United States. It occurs at altitudes of up to 1,800 m (6,000 ft) but in the southern parts of its range seldom occurs above 900 m (3,000 ft). Its range includes riparian zones in the Central Valley and it is common in southern Tulare County and northern Kern County in the drainages of the White River and its tributary, the Arrastre Creek. The habitat is quite variable over different parts of the range but is mainly relatively open oak woodland with interior live oak (Quercus wislizeni), blue oak (Quercus douglasii) and foothill pine (Pinus sabiniana), or sometimes mixed coniferous forest with ponderosa pine (Pinus ponderosa), incense cedar (Calocedrus), white fir (Abies concolor) and California black oak (Quercus kelloggii).

The route began at Camas Meadows in Idaho, went over Targhee Pass, followed the Madison River basin, went over the Gallatin Mountains near Mount Holmes, down Indian Creek to the Gardner River, through Snow Pass to Mammoth Hot Springs, up Lava Creek, through the meadows of Blacktail Deer Creek, to the "Bannock Ford" crossing of the Yellowstone River near Tower Fall, up the Lamar Valley, and over the Absaroka Range into the Clarks Fork Valley. From there, Bannock and Shoshone (often with Flathead and Nez Perce) would choose between the Yellowstone Valley and the Wyoming Basin to hunt bison. For forty years ending in 1878 with the Bannock War, tribes used the Bannock Trail for access to drainages such as the Madison, Gallatin, Yellowstone, Stillwater, Clarks Fork, and Shoshone valleys, and through them to a more distant arc of buffalo ranges.

On reaching the Powder River General Terry learned from General John Gibbon that his scouts had located a large Sioux village that had been seen on lower Rosebud Creek. General Terry believed that the village had gone up the Rosebud and then over western drainages, but he dispatched the Seventh's "right wing" under Major Reno to scout the Powder and the Tongue to ensure that the village had not turned back east. The "right wing" consisted Companies I, E, L, F, and B Company led by "easygoing Tom McDougall". Deviating from General Terry's orders Major Reno shortened his inspection of the Powder River and the Tongue and went over to Reno Creek, where he confirmed a series of large fresh campsites from the Sioux village of some 400 plus lodges as it moved up Rosebud Creek.

On the north shore of the Columbia a new headquarters, Fort Vancouver, became the centerpiece of a multi-post system where furs and supplies were funneled in and out of Fort Vancouver. Brigades of fur trappers would spend months in the wilderness trapping animals, then return with the pelts to fur posts such as Fort George, Fort Umpqua, Fort Walla Walla, Fort Nisqually, Fort Okanogan, and Fort Boise. Later the HBC would start the Puget Sound Agricultural Company to supply food staples to the venture. By the 1830s the Hudson's Bay Company was worried about American expansion into the region and, in an attempt to forestall it, made a policy that fur trapping brigades operating south of the Columbia River, especially in the drainages of the Snake River and Willamette River, would work to create so-called "fur deserts", where beaver stocks were rapidly and deliberately depleted.

Two Ocean Pass separates the headwaters of Pacific Creek, which flows west to the Pacific Ocean, and Atlantic Creek, which flows east to the Atlantic Ocean. At Parting of the Waters, at ,Two Ocean Pass, Wyo, 7.5 Minute Quad, US Topo, USGS, 2012 North Two Ocean Creek flows down from its drainage on the side of Two Ocean Plateau and divides its waters more-or-less equally between its two distributaries, Pacific Creek and Atlantic Creek. From this split, Two Ocean Creek waters flow either to the Gulf of Mexico via Atlantic Creek and the Yellowstone, Missouri and Mississippi Rivers, or to the Pacific via Pacific Creek and the Snake and Columbia Rivers. In the marshy area of Two Ocean Pass adjacent to Parting of the Waters, water actually covers the Continental Divide such that a fish could swim from the Pacific Ocean to the Atlantic Ocean drainages.

Periodically, government of Tamil Nadu also takes up dredging and widening of the canal through Water Resources Department, Public Works Department (PWD). With the provisions of State-Center shared Jawaharlal Nehru National Urban Renewal Mission (JNNURM), PWD has started widening the South Buckingham Canal from Okkiyam Madu to Muttukadu for a stretch of About has been allocated under the JNNURM for integrated development of waterways and macro drainages like Buckingham canal, Otteri Nullah, Virugambakkam – Arumbakkam drain, Cooum and Adyar river. Despite of the development, the central section of the canal running through the most congested areas of Chennai, a length of will remain unnavigable due to severe encroachments and construction of the Chennai Mass Rapid Transport System. On 22 January 2010, Government of Tamil Nadu has reconstituted the Adayar Poonga Trust as Chennai River Restoration Trust for restoration of Chennai rivers (Adayar river, Cooum river) including the Buckingham Canal.

In 1995 a survey of coho salmon south of San Francisco Bay found coho restricted to only one remnant population in Waddell Creek, one small naturalized (hatchery-influenced) population in Scott Creek and a small hatchery-maintained, non-native run in the San Lorenzo River, all in Santa Cruz County. Historically, coho were found in approximately 50 coastal drainages in San Mateo and Santa Cruz counties, but by the 1960s spawning runs were limited to 11 stream systems. The 1995 combined average annual spawning population of native and naturalized coho salmon in Waddell and Scott Creeks was estimated at only 50-60 adults, and none in the San Lorenzo River, comprising only 1.5% of the estimated abundance of coho salmon south of San Francisco Bay in the early 1960s. Coho have returned as a result of stocking efforts at the Kingfisher Flat Hatchery on Scott Creek's Big Creek tributary.

Anadromous steelhead trout (Oncorhynchus mykiss) and coho salmon (Oncorhynchus kisutch) can access approximately of stream between the estuary and natural upstream barriers of the main stem and the three main tributaries, Little, Big, and Mill creeks. In 1995 a review of coho south of San Francisco Bay found coho restricted to only one remnant population in Waddell Creek, one small naturalized (hatchery- influenced) population in Scott Creek and a small hatchery-maintained, non- native run in the San Lorenzo River, all in Santa Cruz County. Historically, coho were found in approximately 50 coastal drainages in San Mateo and Santa Cruz counties, but by the 1960s spawning runs were limited to 11 stream systems.

In accordance with FIGO staging guidelines, comprehensive surgical staging will be conducted to examine the extent of tumor spread via peritoneal regions or lymph drainages. 28% of stage II patients will be found with the development of secondary malignant growths at lymph nodes with a distance from a primary site of cancer, called lymph node metastasis. There are three major lymphatic drainage pathways: # drainage to the paraaortic lymph nodes via ovarian veins # drainage from broad ligament to the iliac lymph nodes # drainage from round ligament to the inguinal lymph nodes Palpation or biopsies of unilateral pelvic and para-aortic lymph nodes will be conducted as a preoperative step to deduce the prognosis of the tumour and lymphatic spread Peritoneal biopsies and omentectomy will also be employed to evaluate the extent of tumour content spillage or implantation in peritoneal cavity. Tumor cells may shed off from the original site into the peritoneal cavity and implant onto the liver capsule surface or diaphragm.

The Brisbane River cod was a unique form of Maccullochella cod that occurred naturally in the Brisbane River system, an east coast river system in south east Queensland, Australia. The Brisbane River Cod was known as the Bumgur (meaning blue cod) by the Jinibara people centred in the Kilcoy region and the junction of the Stanley and Brisbane Rivers. Their exact taxonomic status is not known, but based on several genetic studies it is suspected that Brisbane River Cod were a species intermediate between eastern freshwater cod (Maccullochella ikei) of the Clarence River and Richmond River systems in northern New South Wales and Mary River cod of the Mary River in central Queensland. All naturally occurring Maccullochella cod in east coast drainages ultimately originate from Murray cod, Maccullochella peelii that entered an east coast river system, likely the Clarence, via a natural river capture event somewhere between 0.62 and 1.62 million years ago (mean estimate 1.1 million years ago), as estimated by DNA divergence rates.

Several water refilling stations have opened to serve as an alternative for the residents for their water needs. Also, the city government is continuously implementing solutions in line with the water and sewerage problems of the city such as the construction of deep wells in every barangay and the construction of drainages and canals in those area affected by floods during the rainy and stormy season. Pasa Small Reservoir Irrigation Project (PSRIP) The Pasa Small Reservoir Irrigation Project (PSRIP), a $21.7 million project in Barangay Pasa, a joint undertaking between the South Korean government, through Korea International Cooperation Agency (Koica), and the Philippines, through the National Irrigation Administration and the local government of Isabela. The project entailed construction of a 34-meter high earth-filled dam across Pasa River, a reservoir with an active storage of 3.90 million cubic meters, with 5.93 kilometers of a main canal and 16.20 kilometers of lateral canals.

Numerous stacked sandstone channels can be observed just above Unkar Rapid (River Mile 73) and within side drainages between River Miles 65 and 73. At the base of the Escalante Creek Member, the two intervals of convoluted bedding, which comprise the stratigraphically highest fluid evulsion structures in the Unkar Group, appear to represent the last of the series of earthshocks that began during deposition of the Shinumo Quartzite. Strata containing large sandstone channels of the Escalante Creek Member are overlain by strata containing much smaller channels, such as those of braided streams in a delta, and sheetflow environments, of the Solomon Temple Member. At Mile 64 in Carbon Creek, this part of the Dox Formation consists of stacked, fine-grained sandstone channels that are cut by mud-filled, younger channels. These “cut-and-fill” channel structures are regarded to be indicative of estuarine environments where sea level has fallen and subsequently risen.

South Pass sign The beginnings of the California and Oregon Trails were laid out by mountain men and fur traders from about 1811 to 1840 and were only passable initially on foot or by horseback. South Pass, the easiest pass over the U.S. continental divide of the Pacific Ocean and Atlantic Ocean drainages, was discovered by Robert Stuart and his party of seven in 1812 while he was taking a message from the west to the east back to John Jacob Astor about the need for a new ship to supply Fort Astoria on the Columbia River—their supply ship Tonquin had blown up. In 1824, fur traders/trappers Jedediah Smith and Thomas Fitzpatrick rediscovered the South Pass as well as the Sweetwater, North Platte and Platte River valleys connecting to the Missouri River. British fur traders primarily used the Columbia River and Snake Rivers to take their supplies to their trading posts.

H. lacrima was collected in soil samples at the base of limestone cliffs alongside specimens of Angustopila fabella, and most likely occurs in sympatry with this species on the exposed cliff-faces of Lenglei as has been observed with other hypselostomatids. Many of the recently discovered hypselostomatids of this region have been classified by the authors as being Critically Endangered under IUCN criteria, being restricted (by collection, or nature) to single sites and falling at risk to limestone quarries. Multiple hypotheses of the biogeographical origins of such hypselostomatids have been supported by the authors: firstly, the isolation of populations may be a misconception, and be product of contiguous means of dispersal (cave systems or river drainages) of which only limited components have been studied; secondly, the distributions may be created by rare long-distance dispersal events; or thirdly, that the similarities between allopatric species are the result of convergent evolution. No evidence has thus far been discovered that may reject or prefer one of the three models.

New field work in the Big Belt Mountains suggests that some rocks mapped as the Spokane Formation are conformable with overlying Middle Cambrian strata, and are not part of the Middle Proterozoic Belt Supergroup but are part of strata that may be younger Late Neoproterozoic.DETRITAL ZIRCON EVIDENCE REQUIRES REVISION OF BELT STRATIGRAPHY IN SOUTHWESTERN MONTANA, BALGORD, Elizabeth, MAHONEY, J.
