Northern Montana Water Security Act of 2025

The Northern Montana Water Security Act of 2025 resolves water rights claims for the Fort Belknap Indian Community by ratifying a water rights compact with Montana, allocating 20,000 acre-feet per year of water from Lake Elwell, and authorizing land exchanges to expand tribal land holdings. It establishes a trust fund to support water infrastructure projects and irrigation system rehabilitation, while granting the tribe authority to manage water resources on and off the reservation. The bill resolves historical water rights claims through a comprehensive settlement that includes environmental compliance provisions and detailed water rights administration mechanisms. It provides specific funding mechanisms to carry out water resource development and settlement obligations.
