Dams built by a colony of beaver also help slow the flow of floodwaters and help control erosion. The dam serves keeps a beaver lodge entrance and food storage area under water. Eurasian beavers, however, don't always build lodges-sometimes they dig burrows in stream banks-the entrance is also underwater. Beavers mark their territory with "scent mounds" - piles of mud and sticks that the beaver coats in musk oil.
