As you look out at the creek, look for the beaver lodge and dam in the water. The dam, made of grass, rocks, sticks, and mud, slows down the flow of water in a stream. Beavers build lodges in calm water to live in and keep safe from predators. These round houses are made of sticks and mud. The dams and ponds help control soil erosion and reduce flooding. They are also important habitats for other wetland animals, such as birds and fish. Scroll down to see the Mallows Bay beavers in action!
