Welcome To Diamond Valley Lake

At Southern California's largest reservoir, located in Hemet just 90 minutes from Los Angeles and San Diego, you'll discover some of the greatest fishing in the state. World-renowned for its black bass fishing, Diamond Valley is also home to bluegill and redear sunfish, rainbow trout, and both blue and channel catfish.

An Important Water Resource

Welcome to Diamond Valley Lake

Diamond Valley Lake is a drinking water reservoir built, owned and operated by The Metropolitan Water District of Southern California.

This reservoir is an important component to providing water for 18 million Southern Californians, and is a critical lifeline in times of drought.

To protect this resource, no body contact with the water is permitted. However, the Diamond Valley Aquatic Center, located near the entrance to the lake, allows for plenty of fun in the water. The Diamond Valley Visitor Center and the Western Science Center, which houses 1 million paleo and archaeo artifacts found during the construction of the Lake, are also located at the entrance to Diamond Valley Lake.

The Lake and the surrounding hills have also become known for the spectacular wildflower blooms each spring, and are popular among hikers. Non-motorized bicycles are also permitted on the Lake View Trail, and equestrians can enjoy the North Hills Trail.
