Northeastern Arizona Indian Water Rights Settlement Act of 2025

Summary

Creates and funds a multi-tribal Arizona water-rights settlement that: establishes large, federally funded tribal Water Settlement Trust Funds for the Navajo Nation, Hopi Tribe, and San Juan Southern Paiute Tribe; authorizes construction of the iiná bá – paa tuwaqat’si pipeline and related power facilities; and ratifies and implements a comprehensive Settlement Agreement that resolves, quantifies, and reallocates specific Colorado River and other water entitlements. Implementation and federal disbursements are tied to a defined Enforceability Date that requires multiple conditions (agreements, court decrees, appropriations/transfers, and executed waivers) to be met; if not met by a set deadline the Act is largely repealed and unspent funds revert. The legislation sets up multiple named trust-fund accounts (with authorized investment and withdrawal rules), creates an implementation account for pipeline planning and construction, prescribes tribal withdrawal mechanisms (Tribal management plans or approved expenditure plans subject to Secretary approval), requires specific water accounting rules for Colorado River allocations, authorizes limited tribal leasing/exchange of water, provides limited waivers/releases of claims in exchange for settlement benefits, and includes a narrow waiver of sovereign immunity allowing courts to enforce but not award monetary damages against the tribes for interpretation/enforcement of the Act or Settlement Agreement.

• Creates three federally managed tribal Water Settlement Trust Funds with named subaccounts and federal deposit of over $3.4 billion among them.
• Authorizes $1.715 billion (with $250M pre‑approval limited use) for planning, design, environmental compliance, and construction of the iiná bá – paa tuwaqat’si pipeline (total federal package tied to $5.1364 billion).
• Makes settlement benefits effective only on an Enforceability Date after nine specific conditions are met, and includes a repeal/return-of-funds trigger if not implemented by a statutory deadline.
• Imposes negotiated waivers/releases of many tribal water claims in exchange for quantified water entitlements and monetary benefits, while preserving certain enforcement rights and specified claims.
• Allocates concrete Arizona Colorado River water amounts to tribes and prescribes detailed accounting rules for Colorado River water crediting and leasing/exchange authorities.
• Authorizes tribal withdrawals from trust funds via approved Tribal management plans or Secretary‑approved expenditure plans, and gives the Secretary enforcement authority over misuse.
• Requires Bureau of Reclamation to plan and construct the pipeline, establishes a Project Construction Committee with tribal representation, and ties pipeline design to a prior study alternative.
• Provides a limited waiver of sovereign immunity so courts can interpret/enforce the Act/Agreement but bars suits seeking money damages, costs, or attorney fees against tribes or the U.S. trustee.
• Ratifies and directs implementation of tribal treaties, land trust transfers (~5,400 acres), and requires environmental compliance (NEPA/ESA) in implementation with tribal and federal roles.
