2011 and 2012 Georgiana Slough Non-Physical Barrier Performance Evaluation - GSNPB-12_Legacy_Reports v2

DWR implemented a large-scale experimental testing program in 2011 and 2012 to assess the effectiveness of a non-physical barrier as a method for guiding downstream migrating juvenile salmonids. The experimental design of the 2011 and 2012 tests included the use of acoustically tagged juvenile late fall-run Chinook salmon (2011 and 2012) and steelhead (2012), released upstream of the nonphysical barrier when the barrier was on and when it was off, to determine the effectiveness of the barrier. This report presents the results of the experimental tests conducted in 2012 with additional discussion of the results of tests conducted at Georgiana Slough in spring 2011.
