The Port Gamble Tribe has been working on improving Â a tool that deters beavers and helps fish passage on Martha John Creek this fall. From the North Kitsap Herald:
The county and Port Gamble S’Klallam tribe took action this fall after realizing the “beaver deceiver” on 288th Street was no longer deceiving beavers.
The cheese grater-like device had been installed on a culvert beneath the road a decade ago to keep beavers from blocking the salmon passage with chewed up sticks. It did little to deter the busy rodents, which still managed to cram sticks into the narrow slots in the grating.
The clogged culvert not only blocked chum and coho salmon from reaching the upper reaches of Martha John Creek, but also caused the roadway above to flood during heavy rains.
