Diamond Valley Lake is a lifeline for Southern California in times of drought. The lake holds enough water to meet the area’s emergency and drought needs for six months and is an important component in Metropolitan Water District's plan to provide a reliable supply of water to the 18 million people in Southern California who count on us.
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.
