Diamond Valley
Reservoir Levels • Weather • Hydrology
Diamond Valley Lake in California was created in 1999, and is the largest reservoir in Southern California. The lake is primarily used for municipal drinking water, but it also provides recreational opportunities, such as fishing and boating. The hydrology of the lake is largely dependent on surface flow and snowpack from the San Jacinto Mountains. The lake is managed by the Metropolitan Water District of Southern California, who also operate the Robert B. Diemer Water Treatment Plant. Surrounding the lake is the Diamond Valley Lake Marina, a recreational area that offers fishing, boating, and hiking. In addition, a portion of the surrounding land is used for agricultural purposes, with crops such as grapes and citrus being grown in the area. Overall, Diamond Valley Lake plays a significant role in providing water and recreational opportunities for Southern California.
