Puddingstone Dam is a 147 ft (45 m) high earth and rockfill dam across Walnut Creek in eastern Los Angeles County, California. The dam was built by the Los Angeles Department of Public Works in 1928 and serves mainly for flood control. It forms Puddingstone Reservoir, which can hold more than 20,000 acre·ft (25,000,000 m³) of water.^[1] The reservoir stores floodwater from both the Walnut Creek Wash and the San Dimas Wash, to which it is connected by a short artificial channel.
