B.F. Sisk Dam Raise and Reservoir Expansion Project

Document Description
As a connected action to the B.F. Sisk SOD Modification Project, SLDMWA in collaboration with Reclamation seeks to evaluate increasing storage capacity in San Luis Reservoir for the purpose of providing greater water supply reliability for south-of-Delta contractors dependent on San Luis Reservoir. The increased storage capacity would be achieved by an additional 10-foot raise of the B.F. Sisk Dam embankment across the entire dam crest above the level proposed for dam safety purposes. Increased capacity within San Luis Reservoir would, consistent with the project objectives, be used to store water supply divertible under the existing operation requirements for the CVP and SWP in periods when the existing reservoir would otherwise be full. This stored supply would be used to help meet existing demands under the existing contract supplies and would not serve any new demands or establish any new places of use of CVP or SWP project water. The B.F. Sisk Dam Raise and Reservoir Expansion Project would also implement modifications to State Route 152 in areas where the increased water surface elevation in the reservoir would interact with the roadway.
