This bill amends federal water rights settlement law to create two new funding mechanisms for Native American water rights obligations. It establishes an Operations, Maintenance, Repair, and Ongoing Obligations Subaccount that will receive $45 million annually from 2026 through 2035 to support existing water settlements for tribes including the Ak-Chin Indian Community, Ute tribes, Hualapai Tribe, and Snake River water rights holders. The bill also creates a New and Continuing Settlements Subaccount receiving $250 million per year over the same ten-year period to fund both new and ongoing Indian water rights settlements approved by Congress. These funds will be transferred by the Secretary of the Interior to tribal trust funds and other accounts without requiring additional congressional appropriations, and the Secretary has discretion to determine the timing and amounts of transfers based on settlement obligations. Overall, the legislation commits $2.95 billion over ten years to fulfill the federal government's water rights commitments to Native American tribes.
