The DWP also leases approximately 3,000 acres to government agencies for campgrounds, airports, and scientific projects such as the Cal Tech Radio Telescope and the University of California White Mountain Research Lab. Approximately 2,000 acres of City property is leased for industrial uses where there is no water pollution problem and where industry will not detract from the scenic beauty of the area. These land management policies have helped to develop the potential of the Owens Valley and the Mono Basin for recreation as well as agriculture. In addition, DWP reservoirs at Grant and Crowley lakes have come to afford the residents of California some superb recreational opportunities. Millions of trout are grown in fish hatcheries for release into local streams, and on opening day more than 17,000 anglers start their fishing season on Crowley Lake.
Recreation is now a major part of the region s economy.
