The National Wild and Scenic Rivers System was created by Congress in 1968 (Public Law 90-542; 16 U.S.C 1271 et seq.) to preserve certain rivers with outstanding natural cultural, or recreational features in a free flowing condition for enjoyment of present and future generations. As of January 2000, the National System has grown from its initial eight components to a 156-river system with representation in 37 states.
