Fish Passage Assessments
Since
1998, Ross Taylor and Associates has been a leader in California fish
passage issues. In conjunction with the Five-Counties Salmonid Conversation
Program, Ross Taylor and Associates has inspected 422 stream crossings
in Humboldt, Del Norte, Trinity, Siskiyou, and Coastal Mendocino counties
and performed detailed passage evaluations on 210 stream crossings. With
the results of the Taylor and Associates final reports, the counties submitted
numerous proposals to state and federal funding sources to treat high-priority
migration barriers. As of 2004, the Five-Counties have obtained approximately
4.8 million dollars in restoration funding to implement 32 replacements
and 8 crossing retrofits. Approximately 80 miles of salmon and steelhead
habitat has been re-opened through these efforts.

We can work with you to tailor a fish passage assessment that meets the needs of your agency, entity, watershed group, or private landowner(s). Were able to cost-effectively conduct fish passage assessments ranging from several crossings to hundreds. Although culverts through roads are a major type of crossing, Ross Taylor and Associates has also modified the CDFG protocol to allow for the assessment of hardened fords and low-elevation diversion dams. Regionally, these types of man-made barriers are much more prevalent in central-coast and south-coast California. |
