SB 565, the Navajo Nation Rio San José Stream System Water Rights Settlement Act of 2025, would approve and implement a negotiated settlement of water rights claims involving the Navajo Nation, the State of New Mexico, the United States, and other parties in the Rio San José Stream System. The bill ratifies the underlying settlement agreement, directs the Secretary of the Interior to execute it, and establishes the legal framework for confirming the Navajo Nation’s water rights in the adjudication pending in New Mexico state court. It also sets out definitions, procedures for enforcement, and the conditions that must be met before the settlement becomes enforceable.
The bill creates a Navajo Nation Rio San José Water Rights Settlement Trust Fund and authorizes mandatory federal appropriations of $200,271,000 for the settlement account and $23,000,000 for operations and maintenance, with additional adjustments for cost fluctuations. It allows up to $15 million to be used immediately for planning, engineering, environmental compliance, and installation of groundwater wells and related infrastructure. The measure also authorizes the Navajo Nation to allocate, distribute, and lease its water rights on Navajo lands, and under specified conditions off Navajo lands, including a maximum lease term of 99 years subject to state legislation and federal approval where required.
The bill would significantly affect federal and state water-rights law by confirming the Navajo Nation’s water rights in the Rio San José Stream System and related Rio Puerco Basin claims, while expressly excluding allotment water rights from the Nation’s quantified settlement rights. It also provides that the Nation’s water rights are held in trust by the United States, are not subject to forfeiture through non-use, and may be administered under the Navajo Nation Water Code. In addition, it expands the Navajo-Gallup Water Supply Project service area to serve Navajo communities in the Rio San José Basin, and it requires the State of New Mexico to enact legislation allowing leases of Navajo Nation water rights for up to 99 years as a condition of the settlement’s enforceability.
The overall sentiment reflected in the bill’s status is favorable: the Senate Committee on Indian Affairs ordered the bill to be reported without amendment and favorably, indicating committee support for the negotiated settlement. No recorded votes or committee transcript excerpts were provided, so there is no detailed public debate in the supplied materials. The structure of the bill suggests it is intended as a comprehensive, final settlement that balances tribal water security, state and local water-user interests, and federal trust responsibilities.
The main points of contention embedded in the text concern the scope of the Navajo Nation’s water rights, the treatment of allottee rights, and the extent of releases of claims against the United States and other parties. The bill preserves separate adjudication for allotments and states that allottee rights are not diminished, but it also requires broad waivers and releases for pre-enforceability claims tied to the settlement area. Another potential issue is the off-reservation leasing authority and the requirement for New Mexico to amend state law to permit long-term leases, which may be sensitive for state and local stakeholders. Environmental compliance, judicial review of permit decisions, and the allocation of settlement funds for infrastructure are also areas where implementation details could draw scrutiny.
If enacted, SB 565 would ratify a federal-tribal-state water settlement and create enforceable federal law governing the Navajo Nation’s water rights in the Rio San José Stream System and related Rio Puerco Basin claims. It would establish a federal trust fund, authorize appropriations, define how settlement funds may be spent, and limit future claims through waivers and releases once the settlement becomes effective. The bill would also affect New Mexico law by conditioning enforceability on state legislation allowing 99-year leases of Navajo Nation water rights, and it would expand the Navajo-Gallup Water Supply Project service area for delivery to Navajo communities in the basin.
The available legislative history indicates generally positive support for the bill. The Committee on Indian Affairs ordered it to be reported without amendment and favorably, which suggests the settlement is viewed as a negotiated resolution worth advancing. No vote tally or transcript was provided, so there is no evidence in the supplied materials of organized opposition or divided committee sentiment.
The most notable issues are the breadth of the settlement’s claim waivers, the treatment of allottee water rights, and the conditions placed on off-reservation leasing and state-law changes. Allottees retain separate claims, but the bill also excludes allotment rights from the Navajo Nation’s quantified settlement rights, which can create tension over how water is allocated and administered. State and local parties may also scrutinize the required New Mexico legislative changes, the federal funding commitments, and the settlement’s limits on future litigation and claims against the United States and other parties.
