To help young salmon survive their perilous migration through the Sacramento–San Joaquin River Delta, the Department of Water Resources (DWR) has begun installing a bioacoustic fish fence at the junction of the Sacramento River and Georgiana Slough. Once fully installed, the fence will help sensitive fish species safely traverse through the Delta, including winter-run and spring-run Chinook salmon.  Bioacoustics is a cross-disciplinary science that combines biology and acoustics in the investigation of sound production, dispersion, and reception in animals.
