Beaver damage

Waterway protection

When beavers alter their environment to suit their needs, flooding from beaver dams 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.

Exemptions and permits

  • There are no exemptions for beaver damage.

 

In some cases, flooding can drown stands of trees or dams can block culverts. If a beaver dam is causing damage or is considered a nuisance, they can be removed without a permit, but only if no streambed or lakebed material is removed.

The environmental benefits provided by beaver ponds and wetlands should be weighed against the damage before implementing any beaver control.

Please review the booklet Beaver Damage Control: Guidelines for people with beaver damage problems for solutions that will work best for you.
