Beaver Pipes & Beaver Flow Control Devices

Flood Control

In some situations, a device called a beaver pipe can appropriately resolve flooding problems. Beaver pipes encounter a great deal of problems including costs (about $700 per average culvert or dam), time required to maintain them (at least one visit per year), and the ways beavers outsmart them. For example, if you install a beaver pipe on one dam, the beavers may simply build a new one farther down stream requiring yet another pipe.

Nevertheless, beaver pipe or beaver deceivers as they are some times called, can and do work. They just don't work in every situation.

Pipes work best in the following settings:

1. There must be at least 4 feet of water depth available after the pipe is installed in climates where the water freezes. In other words you must have enough depth so that the beaver can still swim under the ice no matter how thick the ice gets. You will need more depth in more northern locations.

2. Beaver decievers work best in locations where landowners can tolerate some flooding. No matter how good the flow device is, it can't handle the excessive water as occurs from spring melt or torrential downpours. If you are in such an area that you can't handle even some flooding (temporary of course), then a beaver device is not for you.

3. Beaver pipes work best in areas where you don't care about losing trees. Beaver pipes don't protect trees. They only handle water.
