Briones Dam is located in Contra Costa County, California, and was completed in 1964. Its primary purpose is to provide flood control and water supply to the region. The dam impounds the Bear Creek tributary of the San Pablo Reservoir. The hydrology of the area is influenced by the Mediterranean climate, with most of the rainfall occurring between November and April. The dam is primarily fed by surface flows from Bear Creek, but it also receives water from snowpack melt in the surrounding hills during the spring and early summer. The water from the reservoir is used for irrigation and municipal supply, and there are also recreational opportunities such as fishing and hiking in the surrounding Briones Regional Park.
