Description: |
One of the primary methods that ME WS utilizes now is the fence and pipe pond leveler to resolve conflicts with beaver at roadside culverts. This occurs at sites that are conducive for the structure and tend to be a problem annually. The construction materials include a plastic culvert (most often 20' long and 15" diameter), epoxy coated concrete wire mesh (5'x10', 6 gauge, and 6x6" openings), and U-channel sign posts. A cage with a floor is built around the road culvert, the levelling pipe leads from there out to a totally enclosed cage that is submerged in the beaver pond. The enclosed cage is five feet in diameter, with the inlet of the pipe in the center, so that the beavers do not detect the flow of water into the pipe. The beavers focus their damming at the cage that protects the road culvert, and the water continues to flow freely through the levelling pipe. |
