A beaver dam or beaver impoundment is a dam built by beavers; it creates a pond which protects against predators such as coyotes, wolves and bears, and holds their food during winter. These structures modify the natural environment in such a way that the overall ecosystem builds upon the change, making beavers a keystone species and ecosystem ...
Structures formed from plant material include beaver dams, which are constructed by foraged branches and sticks. [22] The dam is a wall of sticks constructed on a moving water source, which forces the water to collect in one area and to stop flowing. [22] Beavers begin to build a dam in an area where rocks and other debris slow the flow of the ...
Research in Washington found that the average summer smolt production per beaver dam ranges from 527 to 1,174 fish, whereas the summer smolt production from a pool formed by instream large woody debris is about 6–15 individuals, suggesting that re-establishment of beaver populations would be 80 times more effective.

Watch on to see the baby beaver swimming along with a tiny branch, doing their part to help mom keep their dam strong and secure. I'll admit, I've watched Wildlife Rescuers' video at least 10 times!
Beaver dam in Tierra del Fuego [1] The North American beaver ( Castor canadensis ) is an invasive species in Tierra del Fuego , at the southern end of Patagonia . Tierra del Fuego is a large island encompassing parts of Chile and Argentina , so that policies and actions to control the species have mainly been binational.
A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions.
Beavers diligently plug leaks in their dams because their survival depends upon the cover provided by the water in their pond. If a beaver can detect the flow of pond water into a pipe, it will plug the pipe with mud and sticks. To be successful, a beaver dam pipe must eliminate the sound and feel of water flowing into the pipe.
