  • M1-Road Fish Passage Improvement Project

    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.

  • Manly Gulch Coho Access and Habitat Restoration Project

    This project replaced a failing road-stream crossing on Camp Road in Manly Gulch — a tributary to the Little North Fork of the Big River flowing through Mendocino Woodlands State Park in Mendocino County — with a 30-foot span timber bridge and realigned approximately 600 feet of channel. Log steps, pools, boulder weirs, rootwads, and a backwater alcove were installed to improve habitat. The project opened approximately 4,000 feet of upstream habitat for federally endangered coho salmon and threatened steelhead, species for which Manly Gulch is designated critical habitat.
