Northern Montana Water Security Act of 2025

The Northern Montana Water Security Act of 2025 (HR 907) establishes a final settlement of water rights for the Fort Belknap Indian Community (Gros Ventre and Assiniboine Tribes) in Montana, confirming their rights to 20,000 acre-feet of water annually from Lake Elwell. The bill ratifies a water rights compact between the tribe and Montana, creates a process for exchanging Federal and State lands, and establishes two trust funds to support water infrastructure projects and management. It includes provisions for the tribe to manage water allocations, lease water rights, and develop infrastructure while protecting allottees' water rights through a Tribal water code. The bill provides specific funding for rehabilitation of the Fort Belknap Indian Irrigation Project and mitigation for the Milk River Project, with implementation requirements and timelines.
