Fish passage programs

In 2003, County Public Works received a grant to evaluate and rank County road crossings on salmonid streams for fish passage. In 2005, the results of that study became the foundation for the Countywide Fish Passage and Creek Restoration Program. The goal of the fish passage program at inception was to construct 10-15 high priority projects over ten years. Since then, the program has undertaken 14 fish passage projects countywide; 12 in the San Geronimo Creek watershed, 1 in the Redwood Creek watershed and 1 in the Novato Creek watershed. Of the 14 projects, 11 have been constructed and 3 are designed and seeking funding. The County has also provided support for several fish passage projects in the Towns of San Anselmo, Fairfax and Mill Valley.
