Beaver Baffler – Stanleys Beaver Baffler

Do you have problems with beavers plugging culverts or causing unwanted flooding of fields, roads, or trails and looking for a solution? If so, you’ve landed on a great website with effective solutions that include the How and Why they work.

The Stan’s Beaver Baffler (SBB) concept is based on a low-cost, low-impact device initially developed in Washington State during the early 1950’s and described in the July 1956 Washington State Game Bulletin.

The goal then and now is to keep culverts functioning and to prevent flooding of infrastructure.

The Stan’s Beaver Baffler protects a reduced pond level and enhanced fish passage by extending a lane fence through a dam notch to the spillway and fast moving water that discourages beaver dam building.

**The Stan’s Beaver Baffler protects a culvert with a wing fence that effectively discourages beaver rebuilding a culvert dam while accommodating beaver passage through the culvert.**

The SBB is based on beaver instincts that discourage them from building problem dams, rather than trying to exclude them.

Stan’s Beaver Baffler is recommended because it serves as a Best Management Practice (BMP) providing beaver friendly and enhanced fish passage. Whereas flowpipe systems constrict or block wildlife/fish passage. It is easily installed by landowners, road crews, and natural resource specialists.
