Carryover Storage and San Vicente Dam Raise Project

Carryover Storage and San Vicente Dam Raise Project

In 1996, as part of its Emergency Storage Project (ESP), the SDCWA approved, and received permits for, a project to raise the 220 foot high San Vicente Dam by 54 feet to increase emergency water storage capacity in San Vicente Reservoir by 52,100 acre-feet, in addition to the existing storage capacity of 90,063 acre-feet. The proposed action involves an additional 63 foot raise of the dam to provide 100,000 acre-feet of carryover storage as part of its Carryover Storage and San Vicente Dam Raise Project (CSP). Because it would not be feasible or practical to construct two separate raises of the dam due to cost, safety of the raised dam structure, and construction logistics, the two increases would be combined and constructed at the same time using roller compacted concrete. The combined ESP and CSP dam raises would add as much as 117 feet to the dam (or a total dam height of up to 337 feet), expanding the usable reservoir capacity by up to 152,100 acre-feet. The purpose of the CSP is to substantially increase the reliability and flexibility of the regional water supply by providing up to 100,000 acre-feet of carryover storage capacity by the year 2011.
