Reservoir Levels

Weather conditions and regulatory restrictions on water deliveries from Northern California can affect our local and state reservoir storage levels.


Changes are a function of each reservoir's unique characteristics, including the movement of imported water supplies and rainfall.

Some reservoirs are more important from a regional water reliability standpoint while others are primarily used by local agencies for operational flexibility.

San Diego County’s reservoir capacity is growing thanks to investments such as the San Vicente Dam Raise. Altogether, about two dozen reservoirs in the county can hold nearly 600,000 acre-feet of water.
