A $1 billion effort to expand the B.F. Sisk Dam in California’s Central Valley was approved in October by the U.S. Dept. of the Interior and San Luis & Delta-Mendota Water Authority. When completed, the project will raise the dam height by 10 ft creating an additional 130,000 acre-ft of storage space in San Luis Reservoir, the nation’s largest offstream reservoir.
The B.F. Sisk Dam Raise and Reservoir Expansion Project will create additional water supply for two million people, over one million acres of farmland and 135,000 acres of Pacific Flyway wetlands and critical wildlife habitat, say officials.
