San Vicente Dam Half-Finished: Water Authority

A dam under construction in Lakeside is half finished.

The project, which began in 2009, has reached the halfway point, and has now exceeded the height of the existing dam, the San Diego County Water Authority announced Wednesday.

The San Vicente Reservoir is one of San Diego's drinking water reservoirs. Raising the dam is part of the Water Authority's emergency storage project, which will secure a water source in the case of an interruption in imported water deliveries.

After the construction is complete, the reservoir will take another few years to fill up.
