A beaver dam bipass
The Sierra Nevada beavers are now using PVC. It's a labor-saving innovation.
Okay, I'm pulling your leg.
I took this photo yesterday in Plumas County, where a homesteading beaver tempted fate by damming the creek next to the local landowner's house.
The "environmental logger" who lives across the road learned of his neighbor's resentment, and advised him to use PVC to trick the beaver.
The PVC device is a called the Clemson beaver pond leveler, but its really just a bipass of sorts.
According to the beaver specialists, "Beavers repair dams in response to the sight, sound, and feel of running water. The Clemson leveler transports water through a dam in such a way that beavers cannot sense it and as a result, beavers don't attempt to plug the leveler."
It doesn't work all the time, but so far it has given this beaver a stay of execution.
