as part of the Water Resources Development Act of 1974. According to the text of the act, the purpose of the establishment was for:

conserving and interpreting an area containing unique cultural, historic, geologic, fish and wildlife, archeologic, scenic, and recreational values, preserving as a natural, free-flowing stream the Big South Fork of the Cumberland River, major portions of its Clear Fork and New River stems, and portions of their various tributaries for the benefit and enjoyment of present and future generations, the preservation of the natural integrity of the scenic gorges and valleys, and the development of the area’s potential for healthful outdoor recreation.

The legislation granted authority for land acquisition to the Army Corps of Engineers, and for managing the area to the
