Diamond Valley Lake
First and foremost, 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's plan to provide a reliable supply of water to the 19 million people in Southern California who count on us.
 

Diamond Valley Lake, in Hemet with easy access to I-215, also provides a vast array of recreational opportunities including: hiking and bike riding through the hill surrounding the reservoir; boating and fishing. Boats are required to have clean-burning engines and meet other criteria.  Please click here for boating rules and regulations. 

 

Swimming, wading and water skiing is not allowed in the lake due to the fact that putting human bodies in contact with the water raises the probability that dangerous pathogens will be introduced into the water and contaminate the lake.

 

The Community Park is a multi-use facility operated by Valley-Wide Recreation and Park District at the lake's east recreation area.  The facility includes an Aquatic Center, lighted soccer fields and ball diamonds and more.  Metropolitan has established a substantial trail system that allows visitors to hike and ride along the hills surrounding the reservoir.

 

To the south of Diamond Valley Lake you'll find more than 13,500 acres of open space called the Southwestern Riverside County Multi-Species Reserve. With the creation of the reserve, Metropolitan forged California's first agreement for multispecies protection and proved that progress need not come at the expense of the environment. The reserve is home to at least 16 sensitive, endangered or threatened native California bird, animal and plant species.

 

Diamond Valley Lake is also home to the Western Science Center. Inspired by the discoveries made during the construction of the reservoir in the mid to late 1990's, the museum houses rich archeological and paleontological finds from the valley's human inhabitants, as well as more than one million prehistoric fossils including mammoths, mastodons and giant long-horned bison.  The facility also functions as an important research and education center.​
