The largest known beaver dam is in Wood Buffalo National Park in Alberta, Canada, and is 775 metres (2,543 ft) long. [8] Satellite photos provided by NASA WorldWind show the dam did not exist in 1975, but it appeared in subsequent images. It has two or more lodges and is a combination of two original dams.
Other building materials, like mud and rocks, are held by the forelimbs and tucked between the chin and chest.

Beavers generally concentrate on building and repairing dams in the fall in preparation for the coming winter. In northern areas, they often do not repair breaches in the dam made by otters, and sometimes breach the dam themselves and lower the water level in the pond to create more breathing space under the ice or get easier access to trees ...
River Otters utilize and/or construct dens adjacent to permanent water and may make conspicuous mud-slides along the the banks of rivers, streams, and lakes where they belly-slide down into the water.
They also found that when beaver dams do present barriers, these are generally short-lived, as the dams are overtopped, blown out, or circumvented by storm surges. [ 37 ] By creating additional channel network complexity, including ponds and marshes laterally separated from the main channel, beavers may play a role in the creation and ...
