Ocmulgee Mounds National Park and Preserve Establishment Act

This bill redesignates the existing Ocmulgee Mounds National Historical Park as Ocmulgee Mounds National Park and establishes a new Ocmulgee Mounds National Preserve in Georgia, to be created once the Secretary of the Interior acquires sufficient land. It authorizes the Secretary to acquire land for both areas only through voluntary means (purchase, donation, or exchange), prohibits eminent domain, and requires a management plan prioritizing preservation of cultural sites sacred to the Muscogee (Creek) Nation. The bill also creates an advisory council with tribal representation, mandates hiring preferences for tribal members, and sets rules for managing hunting and fishing within the preserve under federal and state laws.
