Anybody else here after watching flooded storm drains or culverts?The best way to control beavers is to dig a channel through the dam. Then place a perforated metal culvert in the channel extending maybe 20 feet in front and behind the dam. The beavers cannot hear the running water and will not try to plug up the culvert !! Try it, it works great !!They make a beautiful lakes.holding back water is good for land.Imagine the beaver’s reaction when they go clock in for work.
