In the heart of the gold country, the Auburn State Recreation Area (Auburn SRA) covers 40-miles of the North and Middle Forks of the American river. Once teeming with thousands of gold miners, the area is now a natural area offering a wide variety of recreation opportunities to over 900,000 visitors a year. Major recreational uses include hiking, swimming, boating, fishing, camping, mountain biking, gold panning, equestrian/horseback riding trails and off-highway motorcycle riding. Whitewater recreation is also very popular on both forks of the river, with Class II, III and IV runs. Over 30 -private outfitters are licensed to offer whitewater trips in Auburn SRA. Auburn SRA is made up of the lands set aside for the Auburn Dam. California State Parks administers the area under a contract with the US Bureau of Reclamation.
