When beavers create dams, flooding can result in large areas with deep standing water where once only shallow, slow-moving water existed. When this happens, plants and animals that are adapted to wetlands can appear quickly in the flooded area as new habitat is created.
In some cases, flooding can drown stands of trees or beaver dams can block culverts. If a beaver dam is causing damage or is considered a nuisance, the dam can be removed without a permit, but only if no streambed or lakebed material is removed. Note that beavers are likely to rebuild the removed dam.
Please review the booklet Beaver Damage Control: Guidelines for People with Beaver Damage Problems for solutions that will work best for you.
Beaver Dams and Wetlands
If wetlands will be impacted through the discharge of fill as the result of beaver dam removal, consult the Wetland Regulations page to determine if a permit is required.
