Fence and Pipe Devices
If a roadbed is high enough that a small beaver pond does not pose a threat, the combination of a small culvert protective fence and a Flexible Pond Leveler TM system may be the best beaver management option. This combination of devices has 99% success rate, requires almost no maintenance, controls the location of beaver damming, and preserves the environmental benefits of the beaver pond.
The fence is constructed so that beavers can dam against it, but it keeps them out of the culvert so it remains unobstructed. When the fence is installed a Flexible Pond Leveler is also installed and the pipe is set at the desired pond level. Even though the beavers can dam against the fence and hold back some water, the size of the pond they will be able to create by damming on the fence will be limited by the Flexible Pond Leveler TM. If heavy storm runoff temporarily exceeds the pipe capacity it will flow over the dam on the fence and through the unblocked culvert just as it would have if there were no beaver damming.
