Flow pipe systems and fences are used to protect culverts, bridges, irrigation ditches and typically any source of beaver conflict.
Just like the overflow in your bathtub, utilizing flow pipe systems through the beaver dam make it possible to set the desired water level of the beaver pond. This allows beavers and other wildlife to continue using the habitat while limiting the risk of flooding nearby infrastructure, homes, or other assets.
Natural Improvement Service has developed a reliable low-maintenance flow pipe system utilizing the "beaver proof" Beaver Barrel filter.

Protecting trees and gardens with 10-14 gauge welded wire fencing material is a simple, effective measure against beaver nuisance. This is also an easy way to protect mature or preferred trees while permitting beavers to thin overgrown areas.
