Fish passage program

Since 2005,  12 barrier removal projects have been completed.

The goal of the Fish Passage Program is to construct 10-15 high priority projects. Since 2005,  14 fish passage projects have been designed countywide:

  • 12 in the San Geronimo Creek watershed
  • 1 in the Redwood Creek watershed
  • 1 in the Novato Creek watershed

Of the 14 projects, 12 have been completed. Two projects in San Geronimo Creek watershed have shovel-ready designs but need funding for construction.

The County has also provided support for fish passage projects in:

  • Ross
  • San Anselmo
  • Fairfax
  • Mill Valley


In 2003, the Marin County Department of 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.

Marin County has contributed $1.6 million in funding and grant dollars have contributed $2.5 million in funding.

Fish Passage Program projects have been funded in partnership with the following agencies:

  • County of Marin
  • Fisheries Restoration Grant Program (FRGP)
  • Coastal Conservatory
  • State Parks Proposition 12
  • National Oceanic and Atmospheric Administration (NOAA)
  • Proposition 13
  • Coastal Impact Assistance Program (CIAP)
  • American Rivers
  • Novato Sanitary
  • Marin Municipal Water District (MMWD)
