- Document Description
- The Calaveras Dam Replacement Project (CDRP) includes the replacement of the existing Calaveras dam with a new earth and rock-fill dam that will accommodate a public water supply reservoir of the same size as the original 1920s plans (96,850 Acre Feet) in order to meet Division of Safety of Dams (DSOD) requirements. When the replacement dam is completed, DSOD restrictions will be lifted and the original reservoir pool will be restored to the normal maximum water surface elevation of 756 feet. Construction will take approximately 4 years. The CDRP includes the following: a new dam and spillway, support buildings, haul roads, road improvements, staging, stockpile, borrow and disposal areas and power line upgrades. Project activities include grubbing and grading, demolition, excavation, blasting at borrow areas and within the dam footprint, and tree and vegetation removal. The CDRP will result in the permanent loss of 654 acres of habitat for the California tiger salamander (Ambystoma californiense) and 501.11 acres of habitat for the Alameda whipsnake (Masticophis lateralis euryxanthus).
