Beavers build dams to create ponds in which to build their beaver lodges.  Beavers are brown-furred animals with flat, paddle-like tails.  They live in ponds and streams.  Beavers are known for their skill at cutting down trees with their sharp teeth and building dams.

Beaver

The purpose of the beaver dam is to hold back water and make it form a pond in which the beaver can live.

To build its dam, the beaver gnaws downs trees and drags and floats them to the dam site.  It fastens the logs and twigs in place with rocks and mud until a strong barrier is built.

An ordinary beaver dam may be a 5 feet high and 200 or more feet long.

The beaver builds its lodge with branches and mud, too.  A beaver’s lodge looks like a pile of sticks in the pond.  It is really a one-room house.  The floor of the room is just above the water line.  To enter, the beaver must swim through an underwater door in the floor.  Inside the lodge, protected by thick walls and by underwater doors, the beaver is safe from most enemies.  – Dick Rogers
