A 59 mile stretch of the Missouri River between Gavins Point Dam and Ponca State Park was added to the National Wild and Scenic Rivers System by a 1978 amendment (Section 707 of the National Parks and Recreation Act) to the Wild and Scenic Rivers Act of 1968. Components of the National Wild and Scenic Rivers System are classified as wild, scenic, or recreational, based upon the amount of development existing in the river corridor at the time of designation. The 59 mile reach of the Missouri River from Gavins Point Darn to Ponca State Park was classified as recreational and is known as the Missouri National Recreational River (MNRR). Primary responsibility for implementing the project was assigned to the Secretary of the Interior, while secondary responsibility was given to the Secretary of the Army acting through the Chief of Engineers. In 1980 the Secretary of the Interior and the Chief of Engineers signed a Cooperative Agreement which gave overall administrative authority to the Department of the Interior, while day-to-day management of the river was assigned to the Corps of Engineers.
