The final 2011 Georgiana Slough Non-Physical Barrier Performance Evaluation Project Report was completed on September 5, 2012 and is available under the documents tab below.
Under the federal Endangered Species Act (ESA) the National Marine Fisheries Service (NMFS) issued the 2009 Biological and Conference Opinion (BO) for the Long-Term Operations of the SWP and CVP, for Chinook salmon (Oncorhynchus tshawytscha) and other listed anadromous fish (NMFS 2009). Reasonable and Prudent Alternative Action IV.1.3 of this BO requires that California Department of Water Resources (DWR) and the United States Bureau of Reclamation (USBR) consider engineering solutions to reduce the diversion of juvenile salmonids from the Sacramento River into the interior and southern Delta. DWR has implemented two studies, in 2011 and 2012 at Georgiana Slough to evaluate the performance of a non-physical barrier utilizing Bio-Acoustic Fish Fence™ (BAFF) technology. These studies, the Georgiana Slough Non-Physical Barrier (GSNPB) studies, were conducted in order to prevent out-migrating juvenile Chinook salmon and steelhead (Oncorhynchus mykiss) from entering Georgiana Slough. The GSNPB studies will provide data to support compliance with NMFS BO Action IV.1.3, and may benefit Sacramento River Salmonid populations.
