SR 9 - Gribble Creek Fish Passage - Complete October 2018

In summer 2018, WSDOT contractor crews replaced a culvert that was a barrier to fish passage at Gribble Creek under State Route 9. Crews replaced the old round culverts with a larger culvert. Gribble Creek is located southeast of Mount Vernon in Skagit County. The creek passes through a culvert underneath SR 9 near between SR 538/East College Way and Big Lake.

The End Result
The new culvert at Gribble Creek has helped restore the creek bed to a natural state and improve fish passage for salmon and steelhead, in compliance with the U.S. District Court ruling.
