In 1957, SMUD began construction of the Upper American River Project (UARP), a series of hydroelectric power plants in the Crystal Basin. Today, the UARP is capable of producing 1.8 billion kilowatt-hours of clean, affordable electricity -- enough energy to power about 180,000 homes a year in Sacramento.
As part of this project, SMUD created a network of beautiful mountain reservoirs. Through careful planning with the Forest Service, SMUD built a variety of recreational facilities around the reservoirs. Spanning 85,000 acres of pine and fir forests and traversed by lakes, reservoirs and streams, Crystal Basin offers a diverse range of exciting outdoor adventure. Working together, SMUD and the Forest Service continue to provide land- and water-based recreation opportunities for all visitors to enjoy.
