Why is WSDOT installing engineered logjams in the Skagit River?
There’s a stretch of SR 20 three miles east of Rockport in Skagit County that’s constantly buffeted by the Skagit River, especially during flooding. When the river is running high, it eats at the riverbank and, at times, has threatened to even wash out the road. On several occasions in recent years, we’ve had to line the riverbank with large rocks to protect the highway from the barrage of water. These temporary and costly emergency-repair projects only put a Band-Aid on a bigger problem, and they negatively impacted fish habitat.

The End Result
In an effort to protect the highway and improve the river habitat over the long-term, we’re going to build engineered logjams along the riverbank. The logjams will help buffer the highway from the eroding forces of the river.

Project Benefits
Not only do these logjams protect the highway, they also improve the conditions in the river for fish. The project is a win for drivers, our maintenance crews, and the environment.
