Beaver dams are created as a protection against predators, such as coyotes, wolves and bears, and to provide easy access to food during winter.
Beavers always work at night and are prolific builders, carrying mud and stones with their fore-paws and timber between their teeth.
Because of this, destroying a beaver dam without removing the beavers is difficult, especially if the dam is downstream of an active lodge.
Beavers can rebuild such primary dams overnight, though they may not defend secondary dams as vigorously.
Beavers may create a series of dams along a river.
