This project replaced an undersized, deteriorating corrugated metal culvert on the M-1 Road with a full-sized 96-inch diameter culvert to restore fish passage on No-Name Gulch, a tributary to Big River in Mendocino County, California. The old culvert was a partial barrier to migrating salmonids on a stream identified by NOAA as historically productive habitat. The replacement opens 0.21 miles of spawning and rearing habitat in a high-priority recovery watershed for Central California Coast Coho salmon, North Coast steelhead, and Chinook salmon.
