We have the 2003/4 Triton 1756SC aluminum boats with a Johnson 25 HP 4-stroke outboard motor and Motorguide 43 LB trolling motor. The boats also have 2 fishing seats, depth/fish finders and an aerated live well. The boat capacity is 4 people or 650 lbs.
Except for smallmouth bass, as long as the fish meet the size and limit requirements you can keep them. Smallmouth bass are catch and release only. We do urge people to catch and release the warm water species.
Shore fishing is allowed in designated areas only. There are approximately 3 miles of shoreline accessible. The area is ¼ mile from the parking lot and is a moderate to difficult hike on an unpaved fire road.
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.
