beaver dam
Stick-and-mud blockade
A beaver dam is a barrier built by beavers across streams or rivers, constructed from branches, mud, and debris.
The dam creates a pond that protects the beaver's lodge from predators and provides access to food during winter.
Beaver dams can dramatically alter landscapes, creating wetland ecosystems: The old beaver dam had flooded several acres of woodland.
