Rufus Woods Lake
The Chief Joseph Dam is a concrete gravity dam on the Columbia River, upriver from Bridgeport, Washington. The dam is upriver from the mouth of the Columbia at Astoria, Oregon. It is operated by the USACE Chief Joseph Dam Project Office and the electricity is marketed by the Bonneville Power Administration. History The dam was authorized as Foster Creek Dam and Powerhouse for power generation and irrigation by the ''River and Harbor Act of 1946''. The ''River and Harbor Act of 1948'' renamed the project Chief Joseph Dam in honor of the Nez Perce chief who spent his last years in exile on the Colville Indian Reservation. Because of its lack of fish ladders, Chief Joseph Dam completely blocks salmon migration to the upper Columbia River system. Construction began in 1950, with the main dam and intake structure completed in 1955. Installation of the initial generating units was started in 1958 and completed in 1961. Ten additional turbines were installed between 1973 and 1979, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fish Ladder
A fish ladder, also known as a fishway, fish pass, fish steps, or fish cannon is a structure on or around artificial and natural barriers (such as dams, locks and waterfalls) to facilitate diadromous fishes' natural migration as well as movements of potamodromous species. Most fishways enable fish to pass around the barriers by swimming and leaping up a series of relatively low steps (hence the term ''ladder'') into the waters on the other side. The velocity of water falling over the steps has to be great enough to attract the fish to the ladder, but it cannot be so great that it washes fish back downstream or exhausts them to the point of inability to continue their journey upriver. History Written reports of rough fishways date to 17th-century France, where bundles of branches were used to make steps in steep channels to bypass obstructions. A pool and weir salmon ladder was built around 1830 by James Smith, a Scottish engineer on the River Teith, near Deanston, Perthshire ...

Dams On The Columbia River
There are more than 60 dams in the Columbia River watershed in the United States and Canada. Tributaries of the Columbia River and their dammed tributaries, as well as the main stem itself, each have their own list below. The dams are listed in the order as they are found from source to terminus. Many of the dams in the Columbia River watershed were not created for the specific purposes of water storage or flood protection. Instead, the primary purpose of many of these dams is to produce hydroelectricity. As can be seen in the lists, these dams provide many tens of gigawatts of power. Major dam construction began in the early 20th century and picked up the pace after the Columbia River Treaty in the 1960s, by the mid 1980s all the big dams were finished. Including just the dams listed below, there are 60 dams in the watershed, with 14 on the Columbia, 20 on the Snake, seven on the Kootenay, seven on the Pend Oreille / Clark, two on the Flathead, eight on the Yakima, and ...

Columbia River Bridge (Bridgeport, Washington)
The Columbia River Bridge, also known as the Bridgeport Bridge, at Bridgeport, Washington, was built to span the Columbia River in 1950. Composed of three spans, the bridge is a steel continuous riveted deck truss carrying Washington State Route 17 on a roadway and two sidewalks. The center portion of the bridge spans , flanked by end spans. The north approach span and the south approach span are supported by steel plate girders. The bridge played a significant role in the construction of the Chief Joseph Dam just upstream, as no bridge crossing had previously existed in the area. Construction on the dam started in 1945 and was completed, apart from the powerplant, in 1955. The bridge was designed and built by the U.S. Army Corps of Engineers as part of the Chief Joseph Dam project, and is significant for its association with the project and as a major crossing of the Columbia. The bridge was placed on the National Register of Historic Places The National Register of Hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Coulee Bridge
The Grand Coulee Bridge, or Columbia River Bridge at Grand Coulee Dam, is a through-cantilever steel truss bridge built in 1934–35. It carries State Route 155 across the Columbia River immediately below Grand Coulee Dam, near the city of Grand Coulee, Washington. It was added to the National Register of Historic Places in 1982. . The bridge was built to transport heavy equipment across the Columbia River during the construction of the dam, and thereafter as a permanent highway bridge. As such, it was designed to carry a heavier load than was typical. The bridge is supported by two concrete piers, about high. During construction, one of the piers began to tilt, probably due to fine glacial material under the gravel. Additional supports were added as a temporary measure. It employed between 1,000 and 1,200 men. The piers were later taken down to bedrock using pneumatic caissons.

List Of Largest Hydroelectric Power Stations In The United States
Hydroelectricity is, as of 2019, the second-largest renewable source of energy in both generation and nominal capacity (behind wind power) in the United States. In 2021, hydroelectric power produced 31.5% of the total renewable electricity, and 6.3% of the total U.S. electricity. According to the International Hydropower Association, the United States is the 3rd largest producer of hydroelectric power in the world in 2021 after Brazil and China. Total installed capacity for 2020 was 102,8 GW. The installed capacity was 80 GW in 2015. The amount of hydroelectric power generated is strongly affected by changes in precipitation and surface runoff. Hydroelectric stations exist in at least 34 US states. The largest concentration of hydroelectric generation in the US is in the Columbia River basin, which in 2012 was the source of 44% of the nation's hydroelectricity. Hydroelectricity projects such as Hoover Dam, Grand Coulee Dam, and the Tennessee Valley Authority have become iconi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Power Stations In Washington
This is a list of electricity-generating power stations in the U.S. state of Washington, sorted by type and name. These include facilities that are located in more than one state. In 2020, Washington had a total summer capacity of 30,669 MW through all of its power plants, and a net generation of 116,114 GWh. The corresponding electrical energy generation mix in 2021 was 64.6% hydroelectric, 14.4% natural gas, 7.8% nuclear, 2.9% coal, 8.7% wind, and 1.3% biomass which includes most refuse-derived fuel. Petroleum and utility-scale solar facilities generated most of the remaining 0.3%. Small-scale photovoltaic installations generated an additional net 311 GWh to the state's electrical grid; an amount six times larger than Washington's utility-scale photovoltaic plants. Washington routinely delivers one-quarter of U.S. hydroelectric generation, and hosts the nation's largest capacity power station at Grand Coulee Dam. 60% of Washington households use electricity as the ...

Reservoir
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 A dam is a barrier that stops or restricts the flow of surface water or underground streams ...
