Duncan Dam
Duncan Dam is a dam spanning the Duncan River in the Canadian province of British Columbia. Duncan Dam was the first dam built to satisfy the Columbia River Treaty, initiated after the 1948 flood along the lower Columbia, which proved fatal at Vanport City, Oregon and other locations. Construction began in 1965 and was completed in 1967. It is an earthfill dam with no power generation facilities. It was built as a storage facility, controlling the flow of water from the Duncan River into the Kootenay Lake Kootenay Lake is a lake located in British Columbia, Canada. It is part of the Kootenay River. The lake has been raised by the Corra Linn Dam and has a dike system at the southern end, which, along with industry in the 1950s–70s, has changed ... reservoir. The reservoir's storage is over 50% greater than Kootenay Lake. The reservoir is usually filled by August. The Duncan river drainage basin is 2,400 square kilometers. The dam regulates 10% of the water in the Koot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duncan Lake (British Columbia)
Duncan Lake is a man-made reservoir lake in the Kootenay region of British Columbia, Canada, formed by Duncan Dam and about 45 km in length. It is fed by the Duncan River, which forms part of the boundary between the Selkirk Mountains to the west and the Purcell Mountains to the east. Below Duncan Dam is the head of Kootenay Lake. Prior to inundation there was a lake of shorter length at the same location, also named Duncan Lake but also known as Upper Kootenay Lake or Upper Kootenai Lake. The name comes from the Duncan River's namesake, John "Jack" Duncan, prospector, who ran for election but did not win the Kootenay District seat on the colonial Legislative Council of British Columbia.

Duncan River (British Columbia)
The Duncan River is in the West Kootenay region of southeastern British Columbia. Entering the North Arm of Kootenay Lake, the river is a major tributary of the Kootenay River, which in turn flows into the Columbia River. The Selkirk Mountains lie to the west and the Purcell Mountains to the east. Name origin The earliest known mention of the river name was 1889 in honour of John (Jack) Duncan, a prospector and candidate for the colonial Legislative Council from the Kootenay Land District in 1866. Duncan Lake, which divides the upper and lower parts of the river, takes its name from the latter. The lake was called Ecclesion by Father De Smet on his 1846 map, Upper Kootenay by Moberly around 1866 and Trutch in 1871, Upper Kootenai on government maps in 1890, and Howser by John Retallack and Duncan by Perry in 1893. The name Duncan had prevailed for the lake by 1912 and Howser for the community by 1905. River traffic Thousands of years ago, prior to reclamation by silting, ...

Provinces And Territories Of Canada
Within the geographical areas of Canada, the ten provinces and three territories are sub-national administrative divisions under the jurisdiction of the Canadian Constitution. In the 1867 Canadian Confederation, three provinces of British North America—New Brunswick, Nova Scotia, and the Province of Canada (which upon Confederation was divided into Ontario and Quebec)—united to form a federation, becoming a fully independent country over the next century. Over its history, Canada's international borders have changed several times as it has added territories and provinces, making it the world's second-largest country by area. The major difference between a Canadian province and a territory is that provinces receive their power and authority from the ''Constitution Act, 1867'' (formerly called the '' British North America Act, 1867''), whereas territorial governments are creatures of statute with powers delegated to them by the Parliament of Canada.

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columbia River Treaty
The Columbia River Treaty is a 1961 agreement between Canada and the United States on the development and operation of dams in the upper Columbia River basin for power and flood control benefits in both countries. Four dams were constructed under this treaty: three in the Canadian province of British Columbia ( Duncan Dam, Mica Dam, Keenleyside Dam) and one in the U.S. state of Montana ( Libby Dam). The treaty provided for the sharing with Canada of half of the downstream US power and flood benefits, and allows the operation of Treaty storage for other benefits. The long-term impacts of the treaty have been mixed: while the dams have provided enormous economic benefits to British Columbia and the U.S. Pacific Northwest through hydroelectric generation and flood control, there are longstanding concerns regarding social and economic impacts to the local communities, and the environmental effects associated with the construction and operation of large dams.

Vanport City, Oregon
Vanport, sometimes referred to as Vanport City or Kaiserville, was a city of wartime public housing in Multnomah County, Oregon, United States, between the contemporary Portland city boundary and the Columbia River. It was destroyed in the 1948 Columbia River flood and not rebuilt. It sat on what is currently the site of Delta Park and the Portland International Raceway. History Vanport construction began in August 1942 to house the workers at the wartime Kaiser Shipyards in Portland and Vancouver, Washington. Vanport—a portmanteau of "Vancouver" and "Portland"—was home to 40,000 people, about 40 percent of them African-American, making it Oregon's second-largest city at the time, and the largest public housing project in the nation. After the war, Vanport lost more than half of its population, dropping to 18,500, as many wartime workers left the area. However, there was also an influx of returning World War II veterans. In order to attract veterans and their fami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kootenay Lake
Kootenay Lake is a lake located in British Columbia, Canada. It is part of the Kootenay River. The lake has been raised by the Corra Linn Dam and has a dike system at the southern end, which, along with industry in the 1950s–70s, has changed the ecosystem in and around the water. The Kootenay Lake ferry is a year-round toll-free ferry that crosses between Kootenay Bay and Balfour. The lake is a popular summer tourist destination. Geography Kootenay Lake is a long, narrow and deep fjord-like lake located between the Selkirk and Purcell mountain ranges in the Kootenay region of British Columbia. It is one of the largest lakes in British Columbia, at 104 km in length and 3–5 km in width. It is, in part, a widening of the Kootenay River, which in turn drains into the Columbia River system at Castlegar, British Columbia. Although oriented primarily in a north-south configuration, a western arm positioned roughly halfway up the length of the lake stretches ...

Kootenay Canal
The Kootenay Canal is a hydroelectric power station, located 19 km downstream of Nelson, British Columbia, Canada. Where the Kootenay River flows out of the reservoir formed by the Corra Linn Dam on Kootenay Lake., a canal diverts water to BC Hydro's Kootenay Canal Generating Station. Its construction was a result of the Duncan Dam and Libby Dam providing year round flows into Kootenay Lake. The powerhouse was completed in 1976. Diversion Water enters the canal from the Corra Linn headpond and for much of the year is diverted 4.5 km past Corra Linn Dam, City of Nelson Powerhouse, Upper Bonnington, Lower Bonnington and South Slocan. By diverting water past the older and smaller dams Kootenay Canal can generate more power due to greater head and more modern generators. Powerhouse After passing through the canal and dropping 84 meters through the powerhouse containing four water turbine-electrical generator units, water then returns to the river. Power generated at Koo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corra Linn Dam
Corra Linn Dam is a concrete hydroelectric dam on the Kootenay River between the cities of Castlegar and Nelson, in the West Kootenay region of southern British Columbia. Rapids The Corra Linn Rapids, named after the Falls of Clyde upper falls of Cora Linn, preceded the dam at this location. Neighbourhood The adjacent former train station and neighbourhood were named after the rapids, but the locality has been frequently misspelled as Corra Lynn. Dam For the six-year period after the 1932 opening, the dam was not permitted to raise the level of Kootenay Lake. It operated as a run-of-the-river hydroelectricity plant allowing the spring freshet to pass downstream. After devastating floods to Idaho farmlands in 1938, the International Joint Commission granted two approvals. The first allowed excavation to the outlet of the lake at Grohman Narrows. In 1939, of gravel and of rock were removed, which included rock bluffs on the south side of the river. The narrows was made deepe ...

Dams In British Columbia
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] |
