2016 Clifton Court Forebay Predator Reduction Electrofishing Study
The Clifton Court Forebay (CCF) Predator Reduction Electrofishing Study (Study) was implemented in response to the National Marine Fisheries Service (NMFS) letter dated April 9, 2015, requiring that the California Department of Water Resources (DWR) immediately implement interim measure (a) of condition 3 as part of the larger effort to comply with Reasonable and Prudent Alternative (RPA) Action IV.4.2(2) of the Biological Opinion and Conference Opinion on the Long-term Operations of the Central Valley Project and State Water Project (NMFS 2009 BiOp). The study length totaled three years, beginning with a pilot year effort in 2016. The study electroshocked and removed predators from CCF and transported them to Bethany Reservoir with the goal of decreasing pre-screen loss of protected fish species with an emphasis on Chinook Salmon and steelhead .

PRES 2016 Annual Report During the 2016 pilot study effort reported here, electrofishing was conducted on 11 days during the months of April and May as a preliminary step in fulfilling regulatory obligations under the 2009 National Marine Fisheries Service Biological Opinion and Conference Opinion on the Long-term Operations of the Central Valley Project and State Water Project. This 2016 pilot effort resulted in the removal of 2,059 striped bass, 594 black bass, and 33 catfish from CCF. Size distribution of predatory fish captures suggest that 98.5 percent of striped bass and 37 percent of black bass are below the minimum legal recreational harvest length limit. | PDF | 06/24/26 |
