Olympic Peninsula culverts
Removing culverts to protect Tribal fishing rights
About the Project
The rivers of the Olympic Peninsula are salmon strongholds—they currently hold the most abundant and diverse wild populations of salmon, trout, and char in the contiguous United States. Located in a remote region with little development pressure and cold water assured from the high-elevation Olympic Mountains, these rivers hold the promise of salmon swimming freely a century from now.
Despite promising conditions for survival, salmonids are currently blocked from reaching high-quality spawning and rearing habitat. The problem is not dams, but culverts, which often look like wide pipes built into the ground to allow a stream to pass under the road. These narrow passages can be treacherous for fish, especially during high-flow events. Though small in size, these barriers add up to a big problem: there are more than 500 culverts impeding fish passage in the Olympic Peninsula.
In what has become known as the “culverts case,” federal court decisions set in motion a multi-billion dollar, multi-decade effort in the State of Washington to protect Tribal treaty rights and bring back Pacific Coast salmon by removing road culverts and barriers that block habitat.
The Coast Salmon Partnership is coordinating an effort of four Tribes—Quileute Tribe, Hoh Tribe, Makah Tribe, and Quinault Indian Nation—counties, several federal and state agencies, and environmental organizations to remove the highest priority culverts and secure funding for the effort. With the development of a decision support tool, the groups identified 83 high-priority culvert barriers whose removal or remediation would open 124 miles of habitat (42 percent of the total). Engineering and design of the first set of priority culvert projects began in 2021, to prepare to compete for public funding in Washington’s 2023-2025 biennial budget.
