American beaver are well-known for their dam-building skills. For beaver,
culverts under highways can provide an engineering shortcut. When  beaver build small dams across culverts, they convert the highway’s foundation into a dam. These dams save the beaver signifi cant time and effort; however, most highways are not designed to withstand the water’s force, so such conditions can lead to the
road’s total collapse.
Flooding from beaver ponds can cover large areas, depriving property owners of their use.
Athletic fields, yards, croplands, timberlands, and access roads are just some of the locations where
beaver ponds can create access and use problems. Utility companies often are negatively impacted by beaver pond flooding, which damages infrastructure and limits access to sites.
