California Department of Water Resources Water Flow Experiment Successfully Increases Habitat for Endangered Delta Smelt
By experimenting with how salty ocean water mixes with fresh water within the Suisun Marsh, the Department of Water Resources has found a way to improve habitat conditions for endangered delta smelt within the upper San Francisco Estuary. DWR experimented in August 2018 with using existing water control structures, known as the Suisun Marsh Salinity Control Gates, to direct a pulse of fresh water from the Sacramento River into the salty Bay water of the marsh. Delta smelt move with the tides as they swim through the Delta and Suisun Marsh.
