One of the largest man-made reservoirs in Southern California, Diamond Valley Lake reaches 260 feet deep and is over 4,500 surface acres. The lake reached full pool in 2003 after 4 years of the Colorado River aqueduct filling it. Diamond Valley Lake is surrounded by hiking trails and renowned for some of the best fishing in the state because of its population of black bass. It’s also home to bluegill, sunfish, rainbow trout, and both blue and channel catfish. Since Diamond Valley Lake was created as a protected water source, wading or swimming is not permitted in the lake. To plan a trip to this lake, check out the information available
