Beaver dams typically range in length from a few meters to about 100 metres (330 ft). [6] Canals can be over 0.5 kilometres (1,600 ft) long. [7] The largest known beaver dam is in Wood Buffalo National Park in Alberta, Canada, and is 775 metres (2,543 ft) long. [8]
Dams can range in height from 20 cm (7.9 in) to 3 m (9.8 ft) and can stretch from 0.3 m (1 ft 0 in) 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
In 2014, a review of beaver dams as stream restoration tools proposed that an ecosystem approach using riparian plants and beaver dams could accelerate repair of incised, degraded streams versus physical manipulation of streams. [61] The province of Alberta published a booklet in 2016 providing information on using beaver for stream restoration ...
[22] After the restoration, native North American beaver returned to the area, establishing 3-4 beaver dams. [18] These keystone species have been shown to increase fish, bird and mammal abundance and diversity in California rivers and streams. They also benefit trout and salmon by reducing sediment loads and improve water quality. [23]
The largest such lake grew to about 800 km (500 mi) in length before the failure of its dam. Glacial activity can also form natural dams, such as the damming of the Clark Fork in Montana by the Cordilleran Ice Sheet, which formed the 7,780 km 2 (3,000 sq mi) Glacial Lake Missoula near the end of the last Ice Age.
