Armed with an understanding of beaver biology and behavior, many flow device pioneers have invented effective flow devices to control beaver damning and prevent conflicts with humans. Some examples of successful for device designs include the Clemson Pond Leveler from Clemson University, the “Beaver Deceiver™” by Skip Lisle, and a Pond Leveler pipe design by Michel LeClair.

Unfortunately though, many flow device designs that can be found on the Internet may have unacceptably high failure rates, installation costs or maintenance requirements, resulting in wasted time, money, and potentially worsened damage if the problem was not solved.

Therefore, the Beaver Institute™ will only recommend and certify flow device designs with a proven track record that meet the following criteria:

  1. A large documented sample size of successful installations
  2. A 90% or greater success rate after five years
  3. < 2 hours per year of routine maintenance
  4. A reasonable cost for materials and labor

If you have a flow device design that meets these criteria please contact us. We would be happy to review your information for certification and inclusion on our approved list of flow devices. All Beaver Institute certification decisions are made by our Board of Directors with input from our national Advisory Board.
