Beavers Issues — Tested Solutions

Beaver are native to the North America and inhabit a critical place in the region's aquatic ecosystem. They are important for water retention across the landscape and salmon habitat.

Beaver can also cause frustrating issues around road culverts, houses and planted landscapes. Fortunately, there are cost-effective, long-term solutions to most situations including road culverts, flood gates, beaver ponds, etc.

Beaver State Wildlife Solutions was the first to bring professional “flow device” installation to Oregon in 2015, after training with flow device innovator Mike Callahan, of Beaver Solutions LLC in Massachusetts. These low-maintenance solutions to beaver conflicts have been embraced by highway departments, utility companies, private businesses and landowners, federal and state agencies, watershed councils, and environmental organizations.

We solve beaver conflicts for clients in Oregon, California, and Washington. The tools we use include:

Flexible Pond Leveler

Much like the bathtub drain that prevents water from filling past a set level, the flexible pond-leveler can be extremely effective in reducing flooding by restricting the level of a beaver pond. These devices essentially create a permanent leak in the beaver dam, through a caged intake pipe within the beaver pond. This solution is especially suited for situations where human infrastructure like houses, storm drains, or roads are threatened.

Culvert Fencing

Trapezoidal culvert fencing is extremely effective in protecting road culverts from beaver damming activity. These devices create a structure for beaver to dam along that misdirects the beaver's damming efforts farther away from the culvert. As the beaver move away, the biological cues to dam are diminished and beaver leave the culvert to flow without obstruction.

Pipe and Fence

This solution gives the beaver a surface to dam on near the culvert, through which a flexible pond leveler is installed that moves water into the unobstructed culvert. This device is perfect for narrow stream conditions, where a trapezoidal fence may not be possible, or in places where a small beaver pond is allowable near the road (trapezoidal fencing will drain the beaver pond completely). These devices are very successful, and low maintenance over time.

Tree Protection

In parks, or private lands, sometimes the biggest issue with beaver is their tendency to cut down trees. Effective tree protection is possible through a variety of methods, depending on the desired aesthetic, and the quantity of trees.
