The Diamond will test the resolve of even the most experienced fisherman. However, if you can catch fish here, you can catch fish anywhere.

Monster sized fishes await. Come test your fishing skills at The Diamond today!

Note: The Diamond typically has two fish plants a month dependent on water temperature.

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 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.

The Cost of Inspections

There is a $3 charge for all boaters wanting a boat band upon leaving DVL. Click here (PDF) for more information.
