Facts

• In 1975, the State of New Mexico initiated a general stream adjudication to determine the water rights of major claimants to water from the San Juan River Basin, in anticipation of the Navajo Nation's potential claim for a significant portion of the water. The United States asserted claims on behalf of the Navajo Nation, which also intervened. After extensive litigation and negotiation, a settlement was reached in 2005 among the Navajo Nation, the United States, and the State of New Mexico, which was later approved by Congress in 2009 and funded by the New Mexico Legislature. This settlement aimed to resolve the Navajo Nation’s claims to water in the San Juan River Basin (para 1-3).

Procedural History

• [Not applicable or not found]

Parties' Submissions

• State of New Mexico: Argued for judicial approval of the settlement agreement, which allocated water rights to the Navajo Nation in the San Juan River Basin, emphasizing the settlement's fairness, adequacy, and reasonableness (para 3).
• Defendant-Appellant (Gary Horner): Contended that state law limits water rights to existing beneficial uses, argued against the federal reserved rights doctrine being applied broadly, and challenged the settlement as violating New Mexico law and the doctrine of separation of powers (para 6-7).

Legal Issues

• Whether Indian Tribes are required to prove immediate beneficial use to quantify and preserve their water rights.
• Whether the settlement allocating water rights to the Navajo Nation in the San Juan River Basin is fair, adequate, reasonable, and consistent with the public interest.

Disposition

• The district court's decision to approve the settlement agreement and proposed decrees describing the water rights of the Navajo Nation was affirmed (para 19).

Reasons

• Judge Bruce D. Black, with Chief Judge Linda M. Vanzi and Judge J. Miles Hanisee concurring: The court held that Indian tribes are not required to prove immediate beneficial use to quantify and preserve their water rights, citing federal law and precedents that reserved water rights exist without exercise and may be asserted as prior and more senior to allocated state water rights. The court rejected the appellant's arguments that state law and the New Mexico Supreme Court's decisions limit water rights to existing beneficial uses and that the settlement violates New Mexico law and the doctrine of separation of powers. The court found the settlement to be fair, adequate, reasonable, and consistent with the public interest, noting that it substantially limits the Navajo Nation’s potentially disruptive claims to water rights in the San Juan Basin by adjudicating the Navajo Nation’s water rights in a reduced amount to be exercised almost entirely under a junior priority date, with conditions to protect other water rights in the stream system (para 6-18).
