List Of Hydroelectric 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 reservoir, 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 River, Snake, seven on the Kootenay River, Kootenay, seven on the Pend Oreille River, Pend Oreill ...

Pacific Northwest River System
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Grand Coulee Dam
Grand Coulee Dam is a concrete gravity dam on the Columbia River in the U.S. state of Washington, built to produce hydroelectric power and provide irrigation water. Constructed between 1933 and 1942, Grand Coulee originally had two powerhouses. The third powerhouse ("Nat"), completed in 1974 to increase energy production, makes Grand Coulee the largest power station in the United States by nameplate-capacity at 6,809 MW. The proposal to build the dam was the focus of a bitter debate during the 1920s between two groups. One group wanted to irrigate the ancient Grand Coulee with a gravity canal while the other pursued a high dam and pumping scheme. The dam supporters won in 1933, but, although they fully intended otherwise, the initial proposal by the Bureau of Reclamation was for a "low dam" tall which would generate electricity without supporting irrigation. That year, the U.S. Bureau of Reclamation and a consortium of three companies called MWAK (Mason-Walsh-Atkinson Kier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revelstoke Dam
The Revelstoke Dam, also known as Revelstoke Canyon Dam, is a hydroelectric dam (combined earthfill dam and gravity dam) spanning the Columbia River, north of Revelstoke, British Columbia, Canada. The powerhouse was completed in 1984 and has an installed capacity of 2480 MW. Four generating units were installed initially, with one additional unit (#5) having come online in 2011. The reservoir behind the dam is named Lake Revelstoke. The dam is operated by BC Hydro. History Construction of Revelstoke Dam started in 1978, and was completed in 1983. Areas inundated by the dam include the Dalles des Morts or "Death Rapids", which was the stretch of canyon just above the dam's location, and various small localities along the pre-inundation route of the Big Bend Highway, which was the original route of the Trans-Canada Highway until the building of its Rogers Pass section. Just below the dam was the location of La Porte, one of the boomtowns of the Big Bend Gold Rush and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kinbasket Lake
Kinbasket Lake (or Kinbasket Reservoir) is a reservoir on the Columbia River in southeast British Columbia, north of the city of Revelstoke and the town of Golden. The reservoir was created by the construction of the Mica Dam. The lake includes two reaches, Columbia Reach (to the south) and Canoe Reach (to the north), referring to the river valleys flooded by the dam. To the north it almost reaches the town of Valemount in an impoundment of the Canoe River. To the south it reaches upstream the Columbia River towards the city of Golden. The original, smaller Kinbasket Lake was named in 1866 after Kinbasket, a chief of the Shuswap people. The modern, large lake was created after the completion of the Mica Dam in 1973, and was called McNaughton Lake (after Andrew McNaughton) until 1980. A number of small communities were inundated by the creation of Kinbasket Lake, and comprised a region known as the Big Bend Country, a subregion of the Columbia Country. Among these towns were Mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BC Hydro
The British Columbia Hydro and Power Authority, operating as BC Hydro, is a Canadian electric utility in the province of British Columbia. It is the main electricity distributor, serving more than 4 million customers in most areas, with the exception of the City of New Westminster, where the city runs its own electrical department and portions of the West Kootenay, Okanagan, the Boundary Country and Similkameen regions, where FortisBC, a subsidiary of Fortis Inc. directly provides electric service to 213,000 customers and supplies municipally owned utilities in the same area. As a provincial Crown corporation, BC Hydro reports to the BC Ministry of Energy, Mines and Low Carbon Innovation, and is regulated by the British Columbia Utilities Commission (BCUC). Its mandate is to generate, purchase, distribute and sell electricity. BC Hydro operates 32 hydroelectric facilities and three natural gas-fueled thermal power plants. As of 2014, 95 per cent of the province's electricity was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mica Dam
Mica Dam is a hydroelectric embankment dam spanning the Columbia River 135 kilometres north of Revelstoke, British Columbia, Canada. It was built as one of three Canadian projects under the terms of the 1964 Columbia River Treaty and is operated by BC Hydro. Completed in 1973, the Mica powerhouse had an original generating capacity of 1,805 megawatts (MW). Mica Dam, named after the nearby settlement of Mica Creek and its associated stream, in turn named after the abundance of mica minerals in the area, is one of the largest earthfill dams in the world. The reservoir created by the dam is Kinbasket Lake. Water from the dam flows south directly into Revelstoke Lake, the reservoir for the Revelstoke Dam. Mica Dam is the tallest dam in Canada and second tallest in North America after the Chicoasén Dam in Mexico and it is the farthest upstream dam on the Columbia River. The dam's underground powerhouse was the second largest in the world at the time of its construction, and was the fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units, International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Energy transformation, energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish people, Scottish invention, inventor, mechanical engineer, and chemist who improved the Newcomen steam engine, Newcomen engine with his own Watt steam engine, steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potentia ...

Columbia Lake
Columbia Lake is the primary lake at the headwaters of the Columbia River, in British Columbia, Canada. It is fed by several small tributaries. The village of Canal Flats is located at the south end of the lake. Columbia Lake is a fresh water lake located along Highway 93 and 95, between the centres of Canal Flats and Fairmont Hot Springs in British Columbia, Canada. Its average July temperature of 18 °C makes it the largest warm water lake in the East Kootenay. It has a mean depth of only , to a maximum of , with excellent water clarity as it enjoys a much smaller volume of boat traffic than its northern neighbour, Windermere Lake. The Kootenay River, a major tributary of the Columbia, passes within a few thousand feet of the south end of the lake. In freshets the Kootenay, here already a large stream, sometimes overflows into Columbia Lake, and historically the Baillie-Grohman Canal connected the two bodies of water to facilitate the navigation of steamboat A steamb ...

River Source
The headwaters of a river or stream is the farthest place in that river or stream from its estuary or downstream confluence with another river, as measured along the course of the river. It is also known as a river's source. Definition The United States Geological Survey (USGS) states that a river's "length may be considered to be the distance from the mouth to the most distant headwater source (irrespective of stream name), or from the mouth to the headwaters of the stream commonly known as the source stream". As an example of the second definition above, the USGS at times considers the Missouri River as a tributary of the Mississippi River. But it also follows the first definition above (along with virtually all other geographic authorities and publications) in using the combined Missouri—lower Mississippi length figure in lists of lengths of rivers around the world. Most rivers have numerous tributaries and change names often; it is customary to regard the longest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port
A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories. Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide the labor for processing and handling goods and related services for the ports. Today by far the greatest growth in port development is in Asia, the continent with some of the world's largest and busiest ports, such as Singapore and the Chinese ports of Shanghai and Ningbo-Zhou ...
