San Vincente Reservoir, San Diego County, California


Visited on 6/25/2018 after giving an examination to a Wastewater Treatment Plant Operator for work.  San Vicente Reservoir is a deep, steep-sided impounding reservoir on San Vicente Creek, approximately 25 miles northeast of San Diego. It currently has a depth of 659 feet above sea level when full. Water levels are monitored weekly.

No swimming or wading permitted; body contact only permitted as incidental to water contact activities (water-skiing, wakeboarding, etc.).
The City of San Diego, in partnership with the San Diego County Water Authority, designed and built the dam raise project to ensure a six-month supply of drinking water for the San Diego region in the event imported water deliveries are interrupted or impacted by drought. The dam raise added 152,000 acre-feet of water storage capacity to the reservoir.  San Vicente Reservoir is by far the largest reservoir in San Diego County in terms of water volume and total capacity, more than twice that of the 2nd largest reservoir, El Capitan.

The original dam at San Vicente Reservoir was completed in 1943, creating a reservoir with 1,069 surface acres and 14 miles of shoreline with a maximum depth of 190 feet. In 2009, the San Diego County Water Authority began a project to raise the dam an additional 117 feet, allowing the lake to store an additional 152,000 acre feet of water providing another 500 surface acres. That project was completed in 2012, and the reservoir reopened on September 22nd, 2016 after a new marina and dock facilities were added.
San Vicente Reservoir is now a 1,680 acre lake owned and operated by the city of San Diego.
