Biological Opinion - Fisheries Monitoring

Fisheries Monitoring in Lower Mainstem Russian River Tributaries and Estuary

Regardless of which portion of the Russian River young salmon and steelhead originate, all must travel downstream through the mainstem Russian River and estuary as they make their way to the ocean.  Sonoma Water will monitor the effects that changes in river management related to the Russian River Biological Opinion have on salmon and steelhead populations over time by operating facilities designed to detect the movement of these fish out of tributaries and into the lower river.  Follow-up efforts to capture fish that may reside for extended periods in the estuary will also provide information on growth.
