Cui-ui
The cui-ui (''Chasmistes cujus'') is a large sucker fish endemic to Pyramid Lake and, prior to its desiccation in the 20th century, Winnemucca Lake in northwestern Nevada. It feeds primarily on zooplankton and possibly on nanoplankton (such as algae and diatoms). The maximum size of male cui-ui is approximately and , while females reach approximately and . A cui-ui typically lives for 40 years but does not reach sexual maturity until at least age eight. The cui-ui is an endangered species, and one of the few surviving members of its genus. The cui-ui population is generally improving in numbers, having attained an estimated population exceeding one million in 1993, thanks to the efforts of the U.S. Environmental Protection Agency in analysis of the Truckee River spawning grounds and of the Nevada Department of Environmental Protection and EPA in following up on protection measures. The reason the cui-ui remains endangered (though upgraded from critically endangered in 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DSSAM Model
The DSSAM Model (Dynamic Stream Simulation and Assessment Model) is a computer simulation developed for the Truckee River to analyze water pollution, water quality impacts from land use and wastewater management decisions in the Truckee River Basin. This area includes the cities of Reno, Nevada, Reno and Sparks, Nevada as well as the Lake Tahoe Basin. The model is historically and alternatively called the ''Earth Metrics Truckee River Model''. Since original development in 1984-1986 under contract to the United States Environmental Protection Agency, U.S. Environmental Protection Agency (EPA), the model has been refined and successive versions have been dubbed DSSAM II and DSSAM III. This hydrology transport model is based upon a pollutant loading metric called ''Total maximum daily load (TMDL).'' The success of this flagship model contributed to the Agency's broadened commitment to the use of the underlying TMDL protocol in its national policy for management of most river system ...

Pyramid Lake (Nevada)
Pyramid Lake is the Sink (geography), geographic sink of the basin of the Truckee River, northeast of Reno, Nevada, United States. Pyramid Lake is the biggest remnant of ancient Lake Lahontan, the inland sea that once covered much of western Nevada. It is approximately long and wide, with a perimeter of , covering acres entirely enclosed within the Pyramid Lake Indian Reservation, Pyramid Lake Paiute Tribe Reservation. Pyramid Lake is fed by the Truckee River, which is mostly the outflow from Lake Tahoe. The Truckee River enters Pyramid Lake at its southern end. Pyramid Lake is an endorheic lake, with water leaving only by evaporation or sub-surface seepage. The lake has about 10% of the area of the Great Salt Lake, but it has about 25% more volume. The salinity is approximately 1/6 that of sea water. Although clear Lake Tahoe forms the headwaters that drain to Pyramid Lake, the Truckee River delivers more turbid waters to Pyramid Lake after traversing the steep Sierra terrai ...

Hydrology Transport Model
An hydrological transport model is a mathematical model used to simulate the flow of rivers, streams, groundwater movement or drainage front displacement, and calculate water quality parameters. These models generally came into use in the 1960s and 1970s when demand for numerical forecasting of water quality and drainage was driven by environmental legislation, and at a similar time widespread access to significant computer power became available. Much of the original model development took place in the United States and United Kingdom, but today these models are refined and used worldwide. There are dozens of different transport models that can be generally grouped by pollutants addressed, complexity of pollutant sources, whether the model is steady state or dynamic, and time period modeled. Another important designation is whether the model is distributed (i.e. capable of predicting multiple points within a river) or lumped. In a basic model, for example, only one pollutant mi ...

Truckee River
The Truckee River is a river in the U.S. states of California and Nevada. The river flows northeasterly and is long.U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed October 20, 2012 The Truckee is the sole outlet of Lake Tahoe and drains part of the high Sierra Nevada, emptying into Pyramid Lake (Nevada), Pyramid Lake in the Great Basin. Its waters are an important source of irrigation along its valley and adjacent valleys. Naming of the river A Northern Paiute language, Northern Paiute word for the Truckee is Kuyuinahukwa. Kuyui- refers to the Cui-ui, a species of fish endemic to Pyramid Lake (Nevada), Pyramid Lake which is central to the lives of the Northern Paiute people, Northern Paiute band called the Kuyui Dükadü (cui-ui-fish-eaters). In the Washo language, different parts of the river have different names. Two names, ‘Át’abi wá’t’a and Á’waku wá’t’a translate to "trout stream." The latter na ...

Derby Dam
Derby Dam is a diversion dam built from 1903 to 1905 on the Truckee River, located about east of Reno in Storey and Washoe counties in Nevada, United States. It diverts water into the Truckee Canal that would otherwise enter Pyramid Lake. The canal feeds Lake Lahontan reservoir in the Carson River watershed, where it is used for irrigation. It was the first project of the newly organized U.S. Reclamation Service (known today as the U.S. Bureau of Reclamation), organized by the Reclamation Act of 1902. As a result of the diversion, Winnemucca Lake lost inflow and dried up, and Pyramid Lake lost more than in elevation, resulting in the near-extinction of the Lahontan cutthroat trout. The dam is operated by the Truckee-Carson Irrigation District. It was named after the Derby Southern Pacific Railroad station. History The dam was constructed for the U.S. Bureau of Reclamation following an authorization for construction issued on March 14, 1903. Construction comme ...

Pyramid Lake Paiute Tribe Of The Pyramid Lake Reservation
The Pyramid Lake Paiute Tribe Reservation () is an Indian Reservation in northwestern Nevada, approximately northeast of Reno, in Washoe, Storey, and Lyon counties. It is governed by the federally recognized Pyramid Lake Paiute Tribe, which represents two Northern Paiute bands, the larger Kuyuidökadö (Cui Yui Ticutta) ("Cui-ui-Fish-Eaters") and the smaller Tasiget tuviwarai ("Those who live amidst the mountains"). The reservation lies almost entirely in Washoe County (99.88%), with small amounts of land in the other two counties (at the southern end, near the city of Fernley). In 1993, the population of the reservation was 1,603 individuals. At that time there were 2,253 enrolled members of the tribe. The 2000 census reported a population of 1,734 on the reservation. Together with the Walker River Paiute tribe (two Northern Paiute bands: ''Aga'idökadö (Agai Ticutta)'': "Cutthroat trout Eaters", and ''Pakwidökadö (Pugwi Ticutta)'': "Chub carp Eaters"), in 2016 the Py ...

Biota (ecology)
A biome () is a distinct geographical region with specific climate, vegetation, and animal life. It consists of a biological community that has formed in response to its physical environment and regional climate. In 1935, Tansley added the climatic and soil aspects to the idea, calling it '' ecosystem''. The International Biological Program (1964–74) projects popularized the concept of biome. However, in some contexts, the term ''biome'' is used in a different manner. In German literature, particularly in the Walter terminology, the term is used similarly as '' biotope'' (a concrete geographical unit), while the biome definition used in this article is used as an international, non-regional, terminology—irrespectively of the continent in which an area is present, it takes the same biome name—and corresponds to his "zonobiome", "orobiome" and "pedobiome" (biomes determined by climate zone, altitude or soil). In the Brazilian literature, the term ''biome'' is sometim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potamodromous
Fish migration is animal migration, mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Such migrations are usually done for better feeding or to reproduce, but in other cases the reasons are unclear. Fish migrations involve movements of school of fish, schools of fish on a scale and duration larger than those arising during normal daily activities. Some particular types of migration are ''anadromous'', in which adult fish live in the sea and migrate into fresh water to spawn (biology), spawn; and ''catadromous'', in which adult fish live in fresh water and migrate into salt water to spawn. Marine forage fish often make large migrations between their spawning, feeding and nursery grounds. Their movements are associated with ocean currents and with the availability of food in different area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontology, paleontologist, comparative anatomy, comparative anatomist, herpetology, herpetologist, and ichthyology, ichthyologist. Born to a wealthy Quaker family, he distinguished himself as a child prodigy interested in science, publishing his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the Western United States, American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey, U.S. Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition now known as the Bone Wars. Cope's financial fortunes soured after failed mining ventures i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
