Navajo Nation Rio San José Stream System Water Rights Settlement Act of 2025

Establishes and implements a negotiated water-rights settlement for the Navajo Nation in the Rio San José Stream System: it ratifies an Agreement, puts the Nation’s water rights in federal trust, creates a Navajo Trust Fund with specific federal payments, authorizes construction and expansion of the Navajo‑Gallup Water Supply Project to serve the Rio San José Basin, requires environmental reviews, and conditions the settlement on an "Enforceability Date" made by the Secretary after several findings are met. The Act also requires waivers and releases of many existing claims (with limited exceptions), preserves allottee and trustee claims separate from Nation-wide rights, limits federal liability when appropriations are not provided, and sets rules for state-court review of Navajo Nation water‑use permit decisions.
