Spanning 988,000 acres, with a substantial portion owned by Native Americans, the reservation serves as a vibrant hub for community and cultural preservation. The Tribal Council, headquartered near New Town, plays a crucial role in governance and community services, guided by the principles of responsibility, accountability, and respect for traditional values.

With approximately 17,648 enrolled members, the MHA Nation is dedicated to enhancing the quality of life for its constituents through various programs. Key services include healthcare provided by the Elbowoods Memorial Health Center, law enforcement, and employment opportunities through the Tribal Employment Rights Office (TERO).
