Beaver dams typically range in length from a few meters to about 100 metres (330 ft). [8] Canals can be over 0.5 kilometres (1,600 ft) long. [9] The largest known beaver dam is in Wood Buffalo National Park in Alberta, Canada, and is 775 metres (2,543 ft) long. [10]
In 2007, the world's largest beaver dam – about 850-metre (2,790 ft) in length – was discovered in the park using satellite imagery. [ 26 ] [ 27 ] [ 28 ] The dam, at 58°16.3′N 112°15.1′W / 58.2717°N 112.2517°W / 58.2717; -112.2517 , [ 29 ] about 200 kilometres (120 mi) from Fort Chipewyan, had only been sighted by ...
The largest beaver dam is 2,790 ft (850 m) in length—more than half a mile long—and was discovered via satellite imagery in 2007. [62] It is located on the southern edge of Wood Buffalo National Park in northern Alberta and is more than twice the width of the Hoover Dam which spans 1,244 ft (379 m).

Smallwood Reservoir, Churchill Falls generating station, largest capacity in North America (5,428 MW installed, expandable to 9,252 MW); the world's second-largest reservoir. Ossokmanuan Reservoir , Twin Falls generating station (diverted to Churchill Falls)
Dams can range in height from 20 cm (8 in) to 3 m (10 ft) and can stretch from 0.3 m (0.98 ft) to several hundred meters long. Beaver dams are more effective in trapping and slowly leaking water than man-made concrete dams. Lake-dwelling beavers do not need to build dams. [59] Open-water beaver lodge in Canada
Averaging a major dam every 72 miles (116 km), the rivers in the Columbia watershed combine to generate over 36,000 megawatts of power, with the majority coming on the main stem. Grand Coulee Dam is the largest producer of hydroelectric power in the United States, [1] generating 6,809 megawatts, over one-sixth of all power in the basin.
This is a list of operational hydroelectric power stations in Canada with a current nameplate capacity of at least 100 MW. The Sir Adam Beck I Hydroelectric Generating Station in Ontario was the first hydroelectric power station in Canada to have a capacity of at least 100 MW upon completion in 1922.
