In Spring 2005, Marin County Board of Supervisors voted to establish a County Fisheries Restoration Program aimed at restoring fish passage through county culverts on salmon streams in West Marin. Marin’s watersheds are very important to the recovery of coho salmon populations, as it is estimated that approximately 10% of all California wild coho salmon spawn in streams flowing into Tomales Bay.
The County’s new program will focus on replacing and restoring fish passage at each high priority location. For details on the top dozen priority culverts see: Marin Fish Passage Priorities (pdf).
Upcoming Fish Passage Projects - Summer 2005
Woodacre
Creek at the Woodacre Improvement Club
This undersized culvert with a perched outlet creates a serious barrier
to juvenile salmonids. Restoration includes replacement of the culvert
with an open bottom arch, “day-lighting” 191’ of stream channel which
currently runs under a tennis court, and extensive streambank
restoration. The project will open up 1700’ of fisheries habitat.
Cooperative landowners at the Woodacre Improvement Club have made this
project a priority for the salmon.
Evans
Canyon Fish Passage Project
This large concrete box culvert will be replaced with an open bottomed
arch on this coho salmon stream in the San Geronimo watershed. Habitat
above the structure is rated as good, with dense riparian vegetation and
good spawning gravels.

Marin County was recently awarded a significant grant from San Francisco Bay Regional Water Quality Control Board through Prop 13. The funds are earmarked to complete a series of projects related to restoring aquatic habitat and improving water quality- all beneficial to salmon. The County partnered on the grant with Marin Municipal Water District (MMWD), which funds actions including a sediment study for Lagunitas Creek, 15-30 road restoration projects, a culvert replacement for fish passage, and training on the FishNet roads manual. The project also includes GIS of roads as part of a multi-agency ROADS MOU (pdf) initiated by MMWD with participation by Marin County and other agencies. The ROADS MOU is based on the Guidelines for the Maintenance and Management of Unpaved Roads in the Lagunitas Creek Watershed (pdf) (MMWD 2001).
