The Metropolitan Water District's Diamond Valley Lake Reservoir (near Hemet in Riverside County) was the largest earth-and-rock fill project in the U.S. and was filled with 269 billion gallons by 2002. This reservoir is two miles by five miles in size and 250 to 270 feet deep and is the largest body of fresh water in southern California holding approximately 800,000 acre-feet of water.
Vital water resource
The reservoir doubled southern California's above-ground water storage capacity and was designed to provide both protection against drought and a six-month emergency supply in the event of earthquake damage to a major aqueduct.
The Diamond Valley Lake Reservoir is also linked to Lake Skinner by open space corridors, encompassing a total of 22,000 acres of recreation and open space.
