The project includes a 4,500 acre lake which will be linked to Lake Skinner by open space corridors, for a total of 22,000 acres of recreation and open space. The lake will be two miles wide by five miles in length and 250 to 270-feet deep. The reservoir will be the largest body of fresh water in Southern California and will attract many visitors from all over the country. Recreational areas on both sides of the reservoir will provide major areas for picnics, camping, recreational vehicles, swimming, special event meadows, bicycling, fishing, horseback riding, hiking, golfing, model airplane flying, and a host of other uses. To watch this project come visit the overlook off Highway 79 on Construction Road.
Recreation areas are still under construction.
