Culverts under roads or railroad tracks are very common beaver damming sites. This is because to a beaver a culvert probably seems like a hole in a large dam. Since beavers have an innate ability to plug holes in their own dams, they are very good at damming culverts also. By damming the culvert the beavers can easily and quickly create a large dam and pond. This can cause expensive damage and safety hazards for people.
Historically, trapping was the most common method used to protect culverts from beavers. However, trapping would typically be done after a culvert was plugged and a potentially expensive and/or dangerous situation had already occurred. In addition, following trapping new beavers would usually relocate to the same habitat. Therefore trapping was a short term solution with a high risk for a serious reoccurrence within a year or two.
Fortunately, properly designed and constructed culvert protective devices have proven to be extremely effective in eliminating beaver culvert damming. They also can prevent beaver damming at high risk culverts. Our CulverClear devices have a 98% success rate. (See Studies page) They are so effective we guarantee them.

These systems are custom designed and constructed to account for the unique characteristics of each site. Some variables that affect design include: stream flow, culvert type and size, streambed topography, presence of other beaver dams, beaver food supply, the sound and movement of water in the culvert (important stimuli for beaver damming), the potential for other upstream or downstream flooding conflicts, and the previous use of poorly designed flow devices by others.

Following this site evaluation a recommendation can be made regarding how to protect the culvert from beavers in the most cost-effective and long-term manner. Since nearly every culvert can be effectively protected with a CulverClear TM device, the short term solution of trapping is rarely needed.
Beaver Solutions CulverClear devices can be classified as Culvert Protective Fences, Fence and Pipe Devices, and Diversion Dams.
