Diamond Valley Lake is one of the newest reservoirs in Southern California. Because it serves as a drinking water supply, no water contact is allowed in the lake. That means no swimming, wading, water-skiing, etc. Restrictions limit the types of boats, engines, and fuels which may be used on the lake. There is a 25 MPH Speed Limit. Reservations are recommended because parking space is limited.
Diamond Valley Lake is a popular fishing lake. Recreation boaters enjoy the tranquil atmosphere of the lake without the buzz of personal watercraft or water skiers. The lake is located just south of Hemet in Riverside County and is owned by the Metropolitan Water District of Southern California.
Diamond Valley Lake was built in a saddle between two mountain ranges. It has a pair of two-mile long dams, one at each end of the valley. A third, smaller dam, is on the north side.

Diamond Valley Lake is considered one of the top fishing lakes in California. With restrictions on boating and water sports, anglers can enjoy great fishing all over the lake. Game fish include largemouth and smallmouth bass, rainbow trout, bluegill, sunfish, catfish, and carp. Only 1.5 miles of shoreline are open to fishing.
