ABOUT
About Diamond Valley Lake & Marina
In 1998, California Department of Fish and Game Biologist Mike Giusti began cultivating a model, multi-tier fishery. Black bass, perhaps the favorite quarry of Southern California fishermen, were established with broodstock in a rearing pond, built in what is now the lake bottom. With that head start, the first spawn are now as large as three pounds.
Water began pouring into the reservoir in November 1999 and the lake was filled by early 2002. Diamond Valley Lake holds 800,000 acre-feet, or 260 billion gallons of water. By comparison, Lake Havasu, on the Colorado River, holds just 648,000 acre-feet or 201 billion gallons.
Diamond Valley Marina is a food, retail, and recreation concessionaire operated by Vista Recreation to serve the public as authorized by the United States Department of the Interior and the National Park Service.

An Important Water Resource
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 Western Science Center, which houses 1 million paleo and archaeo artifacts found during the construction of the Lake, is also located at the entrance to Diamond Valley Lake.
