Geography
The dam controls flooding from San Dimas Creek, a major San Gabriel Mountains drainage and tributary of the San Gabriel River.
The dam is 145 feet (44 m) high and 265 feet (81 m) long, with a storage capacity of 1,515 acre feet (1,869,000 m3) of water.
As a flood control facility the San Dimas Reservoir is dry for most of the year, only storing water after significant winter storms. The regulation provided by the dam allows for the efficient diversion of floodwaters from San Dimas Wash to Puddingstone Reservoir, which protects the San Dimas area of the San Gabriel Valley.
