Renames Ocmulgee Mounds as a National Park, creates a new National Preserve next to it, and directs the National Park Service to manage both together under a new plan developed with Tribal input. It allows the federal government to buy or accept land only from willing sellers, protects access to sacred and cultural sites, and permits regulated hunting and fishing in the preserve.

It forms an Advisory Council to guide management and require recommendations on how to respect Tribal interests. About 126 acres owned by the Tribe are taken into federal trust for the Tribe. Existing operations at Bond Swamp National Wildlife Refuge continue, military overflights and State wildlife authorities are not affected, and Congress authorizes “such sums as are necessary” to carry out the Act.
