San Vicente Dam, Lakeside, CA to be raised by 117-ft
The San Diego County Water Authority board of directors last week certified the environmental impact report to raise San Vicente Dam by 117 ft.
The $568-million project, to be built on top of the existing San Vicente Dam in Lakeside, will expand the reservoir to hold an additional 52,000 acre-ft of water for use during emergencies and another 100,000 acre-ft of water to supplement imported supplies during dry periods.
The Dam will be constructed of roller compacted concrete and will reportedly be the largest dam raising ever performed in the US and the largest using roller compacted concrete in the world. (Photo by O’Connor Construction Management, Inc.)
