San Dimas Dam, Gravity dam in Los Angeles County, United States.
The San Dimas Dam rises 339 feet high and stretches 130 feet across, creating a reservoir with a storage capacity of 1,515 acre-feet of water.
The Los Angeles County Flood Control District constructed the San Dimas Dam in 1922 to manage flooding from San Dimas Creek, a major tributary of the San Gabriel River.
The dam represents early 20th-century engineering solutions implemented by Los Angeles County to address water management challenges in Southern California's variable climate.
During most of the year, the reservoir remains empty, filling only after winter storms, which allows efficient diversion of floodwaters to Puddingstone Reservoir.
The dam functions primarily as a flood control structure rather than water storage, permitting water to seep underground after storms for natural groundwater replenishment.
