This is a list of dams and water reservoirs in Canada .
The Madawaska River is a river in the Saint Lawrence River drainage basin in Ontario, Canada. The river is 230 km (143 mi) long and drains an area of 8,470 km2 (3,270 sq mi). Its name comes from an Algonquian band of the region known as "Matouweskarini", meaning "people of the shallows".
The Ogoki River is a river in the Thunder Bay and Cochrane Districts of Ontario. It springs from the wilderness just east of Savant Lake, flowing north of Lake Nipigon to Ogoki, where it joins the Albany River which empties into James Bay. The river is 480 kilometres (300 mi) long.
The Saint-Maurice River is one of the main tributaries of the St. Lawrence River, after the Ottawa and the Saguenay Rivers and drains an area of 42,735 km2. It touches the Lake Saint John watershed to the north; the Nottaway River watershed, a major tributary of James Bay, to the northwest; and the southwestern tributaries of the Ottawa River. The Saint-Maurice River is located on the north shore of the St. Lawrence River in Quebec, Canada.
The Manicouagan or Manicuagan River, often clipped to Manic, is a river in Côte-Nord region of Quebec, Canada. The river originates in the Manicouagan Reservoir and flows approximately 200 kilometres (120 mi) south, emptying into the Saint Lawrence River near Baie-Comeau. The reservoir, also known as Lake Manicouagan, lies within the remnant of an ancient eroded impact crater (astrobleme). It was formed following the impact of a 5 kilometres (3.1 mi) diameter asteroid which excavated a crater originally about 100 km (62 mi) wide, although erosion and deposition of sediments have since reduced the visible diameter to about 72 km (45 mi). The Manicouagan impact structure is the sixth-largest confirmed impact crater known on earth.
The Robert Moses Niagara Hydroelectric Power Station is a hydroelectric power station in Lewiston, New York, near Niagara Falls. Owned and operated by the New York Power Authority (NYPA), the plant diverts water from the Niagara River above Niagara Falls and returns the water into the lower portion of the river near Lake Ontario. It uses 13 generators at an installed capacity of 2,525 MW (3,386,000 hp) with an average annual net generation of 15,897,000 MWh between 2014 and 2023, and a capacity factor of 71.9%.
According to the International Hydropower Association, Canada is the fourth largest producer of hydroelectricity in the world in 2021 after the United States, Brazil, and China. In 2019, Canada produced 632.2 TWh of electricity with 60% of energy coming from Hydroelectric and Tidal Energy Sources).
Hydro-Québec is a government-owned public utility established in 1944 by the Government of Quebec. The company is in charge of the generation, transmission and distribution of electricity across Quebec. Its head office is located in Montreal.
The Daniel-Johnson dam, formerly known as Manic-5, is a multiple-arch buttress dam on the Manicouagan River that creates the annular Manicouagan Reservoir. The dam is composed of 14 buttresses and 13 arches and is 214 km (133 mi) north of Baie-Comeau in Quebec, Canada. The dam was constructed between 1959 and 1970 for the purpose of hydroelectric power production and supplies water to the Manic-5 and Manic-5-PA power houses with a combined capacity of 2,660 MW. The dam is 214 m (702 ft) tall, 1,314 m (4,311 ft) long and contains 2,200,000 m3 (2,900,000 cu yd) of concrete, making it the largest dam of its type in the world.
Manic-1 is a hydroelectric power station and dam at the mouth of the Manicouagan River 3 km (1.9 mi) west of Baie-Comeau, Quebec, Canada. The power station was commissioned between 1966 and 1967 and producing 184 MW, it is the smallest of the Manicouagan-Outardes project.
The McCormick generating station is a dam and power station built on the Manicouagan river by the Quebec & Ontario Paper Company and the Canadian British Aluminium Company 3 km (1.9 mi) west of Baie-Comeau, Quebec, Canada. It is named after colonel Robert R. McCormick (1880–1955), who owned and published the Chicago Tribune.
Outardes-2 is a hydroelectric power station and dam on the Outardes River 15 km (9.3 mi) southwest of Baie-Comeau, Quebec, Canada. The power station was commissioned in 1978 and is run-of-the-river.
Outardes-3 is a hydroelectric power station and dam on the Outardes River 55 km (34.2 mi) northwest of Baie-Comeau, Quebec, Canada. The power station was commissioned in 1969 and is run-of-the-river.
Outardes-4 is a hydroelectric power station and dam on the Outardes River 70 km (43.5 mi) northwest of Baie-Comeau, Quebec, Canada. The power station was commissioned in 1969 and is supplied by the Outardes-4 Reservoir which is created by seven additional dams.
The Bersimis-1 generating station is a dam and a hydroelectric power station built by Hydro-Québec in conjunction with Perini, Atlas and Cartier construction companies on the Betsiamites River, in Lac-au-Brochet, 85 km (53 mi) north of the town of Forestville, Quebec. Construction started in 1953 and the power station was commissioned in 1956 with an initial nameplate capacity of 912 megawatts.
The Pipmuacan Reservoir is a man-made lake on the boundary of the Saguenay–Lac-Saint-Jean and Côte-Nord regions of Quebec, Canada, about 130 kilometres (81 mi) north of Chicoutimi. It is used to control the flow for downstream hydro-electric generating stations on the Betsiamites River and, through Lake Pamouscachiou, also on the Shipshaw River. It has a total surface area of 978 square kilometres (378 sq mi) and a net area of 802 square kilometres (310 sq mi).
The Ivanhoe River is a river in Cochrane District and Sudbury District in Northeastern Ontario, Canada. The river is in the James Bay drainage basin and is a left tributary of the Groundhog River.
Black Donald Lake is a reservoir lake in the Township of Greater Madawaska, Renfrew County, and the Township of North Frontenac, Frontenac County, in Eastern Ontario, Canada. It is on the Madawaska River and is part of the Saint Lawrence River drainage basin.
The Rapides-des-Coeurs generating station is a hydroelectric plant and dam erected on the Saint-Maurice River by Hydro-Québec near of Windigo, in the administrative region of Mauricie, in Quebec, in Canada. This plant and the Chute-Allard Generating Station located upstream were put into service in 2008. The construction was completed in 2009.
The Rapide-Blanc generating station is a hydroelectric facility, comprising a reservoir, a dam and a hydroelectric plant. It is located on the Saint-Maurice River about sixty kilometres (37 mi) north of the city of La Tuque, in Quebec, in Canada. Built between 1930 and 1934 by the Shawinigan Water & Power Company (SWPC), it is the third hydroelectric facility on this river. The plant has been operated by Hydro-Québec since it was acquired from the SWPC in 1963, as part of the nationalisation of electric power companies in Quebec. The plant has a rated power of 204 megawatts (274,000 hp).
The Toulnustouc River is a tributary of the Manicouagan River in Rivière-aux-Outardes, Côte-Nord, Quebec, Canada. It is dammed to form Lake Sainte-Anne, which regulates water supply to the huge hydroelectric plants near the mouth of the Manicouagan and also feeds the Toulnustouc generating station with a capacity of 526 MW, which has been operational since 2005.
