�� Diamond Valley Lake

Diamond Valley Lake is a man-made off-stream reservoir located near Hemet, California, United States. It is one of the largest reservoirs in Southern California and one of the newest. It has a capacity of 800,000 acre-feet (990,000,000 m3). In terms of surface area, it is the largest lake wholly within Riverside County and the Inland Empire, but it is smaller than the Salton Sea. The lake nearly doubled the area's surface water storage capacity and provides additional water supplies for drought, peak summer, and emergency needs.
