Calaveras Dam Replacement Project

Calaveras Dam Replacement Project

Calaveras Reservoir, located on the boundary of Alameda and Santa Clara counties, approximately 10 miles southeast of Fremont, California, is the largest Bay Area reservoir in the San Francisco Public Utility Commission's regional water system. Calaveras Dam is located near a seismically active fault zone and was determined to be seismically vulnerable by the California Department of Water Resources, Division of Safety of Dams (DSOD). DSOC has limited since 2001 the amount of water that can be stored in the reservoir to approximately 40 percent of its former full storage capacity (full storage capacity is 96,850 acre-feet of water) until the safety deficiencies are corrected. The Calaveras Dam Replacement Project, as proposed by the San Francisco Public Utilities Commission, includes replacement of the existing dam with one of equivalent height, restored reservoir storage to its full design level, and improved seismic design. Calaveras dam would be operated to release up to 6,300 acre-feet per year of water for the enhancement of fisheries and the other natural resources of Calaveras and Alameda Creeks. The new dam would be constructed at the downstream edge of the existing dam.
