Antelope Reservoir
Antelope Reservoir is a large body of water impounded for irrigation in a semi-arid region of southeastern Oregon in the United States. Located near the small city of Jordan Valley in Malheur County, it is about west of Oregon's border with Idaho. Although the lake is formed by a dam across Jack Creek, most of the water enters the reservoir via the Antelope Feeder Canal. It diverts water to the reservoir from nearby Jordan Creek at a point near the Idaho border. Jack Creek, which carries minor outflows from the reservoir, empties into Jordan Creek further downstream. History The lake was originally formed by a high dam, built in 1913–14, on Jack Creek. At that time, the water in the reservoir came from intermittent surface streams. The dam, managed by the Jordan Valley Irrigation District, was raised to in 1933, and in addition to the intermittent flows the higher dam impounds water from Jordan Creek. The water is used to irrigate about of farmland downstream of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plumas County, California
Plumas County () is a county in the Sierra Nevada of the U.S. state of California. As of the 2020 census, the population was 19,790. The county seat is Quincy, and the only incorporated city is Portola. The largest community in the county is East Quincy. The county was named for the Spanish ''Río de las Plumas'' (the Feather River), which flows through it. The county itself is also the namesake of a native moth species, ''Hadena plumasata''. History Before the California Gold Rush of 1849, the indigenous Mountain Maidu were the primary inhabitants of the area now known as Plumas County. The Maidu lived in small settlements along the edges of valleys, subsisting on roots, acorns, grasses, seeds, and occasionally fish and big game. They were decentralized and had no tribal leadership; most bands lived along waterways in and around their own valleys. Areas with high snowfall, including the Mohawk and Sierra valleys, were hunting grounds for game in the warmer months. In 1848 ...

Dams In Oregon
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoirs In Oregon
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin of the re ...

Methylmercury
Methylmercury (sometimes methyl mercury) is an organometallic cation with the formula . It is the simplest organomercury compound. Methylmercury is extremely toxic, and its derivatives are the major source of organic mercury for humans. It is a bioaccumulative environmental toxicant. Structure and chemistry "Methylmercury" is a shorthand for the hypothetical "methylmercury cation", sometimes written "''methylmercury(1+) cation''" or "''methylmercury(II) cation''". This functional group is composed of a methyl group bonded to an atom of mercury. Its chemical formula is (sometimes written as ).The Methylmercury compound has an overall charge of +1, with Hg in the +2 oxidation state.Methylmercury exists as a substituent in many complexes of the type (L = Lewis base) and MeHgX (X = anion). As a positively charged ion it readily combines with anions such as chloride (), hydroxide () and nitrate (). It has particular affinity for sulfur-containing anions, particularly thiols (). ...

Trout
Trout are species of freshwater fish belonging to the genera '' Oncorhynchus'', ''Salmo'' and ''Salvelinus'', all of the subfamily Salmoninae of the family Salmonidae. The word ''trout'' is also used as part of the name of some non-salmonid fish such as ''Cynoscion nebulosus'', the spotted seatrout or speckled trout. Trout are closely related to salmon and char (or charr): species termed salmon and char occur in the same genera as do fish called trout (''Oncorhynchus'' – Pacific salmon and trout, ''Salmo'' – Atlantic salmon and various trout, ''Salvelinus'' – char and trout). Lake trout and most other trout live in freshwater lakes and rivers exclusively, while there are others, such as the steelhead, a form of the coastal rainbow trout, that can spend two or three years at sea before returning to fresh water to spawn (a habit more typical of salmon). Arctic char and brook trout are part of the char genus. Trout are an important food source for humans and wildlife, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
