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

Authorizes and implements a negotiated water-rights settlement that resolves most Navajo Nation claims in the Rio San José Stream System by creating a federal trust fund, directing multiyear Treasury payments and state contributions, and confirming a multi‑party Agreement. It also authorizes limited state-court judicial review of certain Navajo Nation water-permit decisions, preserves separate rights for individually allotted lands, enables expansion of the Navajo‑Gallup Water Supply Project to serve Rio San José Basin communities, and sets conditions that must be met before the settlement becomes enforceable.
