This bill ratifies a negotiated settlement between the Agua Caliente Band of Cahuilla Indians, the Coachella Valley Water District (CVWD), Desert Water Agency (DWA), and the United States. It confirms and declares valid a Tribal Water Right to produce and use up to 20,000 acre-feet per year (AFY) of groundwater, places that right in federal trust for the Tribe and Allottees, preempts specified state/local groundwater charges (the RAC), and authorizes tribal fees and a tribal possessory-interest tax to replace Riverside County’s ad valorem tax on such interests.
The Act creates an Agua Caliente Settlement Trust Fund with four accounts and mandatory Treasury transfers totaling $500 million ($300M development, $100M groundwater augmentation, $50M water management, $50M OMR), establishes conditions for an enforceability date (including a Final Decree and deposited funds), directs land transfers into trust and the sale of certain federal parcels to CVWD, and requires waivers/releases of many water claims while explicitly reserving environmental and other specified rights. Professionals in water management, municipal finance, tribal government, and land use should read the bill for the mix of confirmed federal reserved rights, funding mechanics, tax preemption, and the compliance and administrative roles assigned to the Secretary and the Tribe.
At a Glance
What It Does
The bill ratifies a May 19, 2025 Settlement Agreement, confirms a 20,000 AFY tribal groundwater right held in trust by the United States, creates a multi-account Settlement Trust Fund with $500 million in mandatory transfers, and authorizes transfers of specified federal land into tribal trust and the sale of the Whitewater River Recharge Facility land to CVWD. It also preempts the application of the local RAC and replaces the Riverside County possessory-interest tax with a Tribal Tax framework.
Who It Affects
The Tribe and enrolled Allottees, CVWD and DWA (water districts operating in the Indio Subbasin), Riverside County and other local taxing entities (through the possessory-interest tax replacement), federal agencies (Secretary of the Interior), and any off‑Reservation lessees or third parties who may receive Tribal Water Right leases or deliveries.
Why It Matters
The bill converts a negotiated settlement into federal law: it creates a quantifiable, prior federal reserved groundwater right; it channels a large federal cash package into tribal-controlled accounts with Secretary oversight; it reshapes local revenue flows by preempting county possessory taxation in favor of tribal taxation; and it relocates significant BLM lands into trust, with limits (including a gaming restriction).

What This Bill Actually Does
The Act implements a comprehensive, legally binding settlement by ratifying an existing written Agreement between the Tribe, CVWD, DWA, and the United States. Central to that settlement is a confirmed Tribal Water Right: the Tribe may Produce and/or Use up to 20,000 acre-feet per year of groundwater in the Indio Subbasin, with a priority date tied to late‑19th century Executive Orders.
The United States will hold that right in trust for the Tribe and Allottees; the right is protected from forfeiture for nonuse and may be leased off‑reservation subject to Secretary approval and a 99‑year maximum term.
Money follows the settlement. The Secretary must establish an Agua Caliente Settlement Trust Fund with four accounts (development, groundwater augmentation, water management, and operation/maintenance/replacement).
The bill mandates Treasury transfers totaling $500 million into those accounts and allows the Tribe to withdraw funds under either an approved Tribal management plan (per the American Indian Trust Fund Management Reform Act) or Secretary‑approved expenditure plans. The Development Account makes $50 million immediately available on deposit for project implementation; other withdrawals are conditional on approved plans and Secretary oversight.
Title and operation of projects built with trust funds will generally remain with the Tribe unless the Tribe agrees otherwise; operation, maintenance, and replacement costs are likewise principally a tribal responsibility except where the Agreement provides otherwise.The Act resolves many disputes by requiring mutual waivers and releases: on the Enforceability Date the Tribe and the United States (for Allottees) waive certain water claims against CVWD and DWA and the Tribe waives certain claims against the United States arising before the Enforceability Date. Environmental claims under major federal statutes (CERCLA, SDWA, Clean Water Act) are explicitly preserved.
The bill also preempts certain state and local charges: the Tribe’s Tribal Production Fee, Tribal Water Fee, and Tribal Water Delivery Charge govern uses of the Tribal Water Right and the Tribal Tax replaces the Riverside County ad valorem possessory-interest tax for taxable periods when the Tribe imposes it. The Tribe must distribute tax proceeds to Other Public Agencies at least to the extent they would have received county proceeds, subject to a cap preventing larger combined receipts than would have occurred absent preemption.Land and infrastructure actions are specific and conditional: a set of BLM‑administered parcels are to be transferred into trust for the Tribe (not eligible for IGRA gaming), the Secretary must convey the Whitewater River Recharge Facility land to CVWD for fair market value if CVWD timely offers to buy, and cultural‑resource protections and stop‑work/consultation rules apply to discoveries of tribal cultural resources during ground‑disturbing activities.
The enforceability date is deliberate: it requires executed Agreement amendments if necessary, Secretary execution, deposit of funds, a Final Decree entered by the federal court, and execution of the waivers/releases; failure to meet the deadline triggers expiration consequences and potential return of unspent funds.
The Five Things You Need to Know
The bill confirms a federal reserved Tribal Water Right of up to 20,000 acre-feet per year in the Indio Subbasin and gives that right a priority no later than the 1876–1877 Executive Orders establishing the Reservation.
It creates an Agua Caliente Settlement Trust Fund with four accounts and mandates $500 million in Treasury transfers: $300M (development), $100M (groundwater augmentation), $50M (water management), and $50M (operation/maintenance/replacement).
On deposit, $50 million from the Development Account is available immediately for implementation and initial development projects; other withdrawals require Secretary‑approved tribal management or expenditure plans and allow Secretary enforcement actions if plans are violated.
The Tribe may lease Tribal Water Right off‑reservation but any lease (including renewals) is capped at 99 years and requires Secretary approval; Allottees must generally exhaust tribal remedies under the Tribe’s Water Ordinance before pursuing certain federal claims under the 1887 Act.
The Act preempts Riverside County’s ad valorem possessory‑interest tax on reserved lands when the Tribe imposes a Tribal Tax, requires distribution to Other Public Agencies consistent with the county Tax Apportionment Schedule, and bars trust lands taken under this section from eligibility for class II or III gaming.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Objectives of the settlement
This section lists the Act’s goals: a final settlement of Agua Caliente and U.S. trustee claims to water in California, resolution of disputes over local fees (RAC), authorization for ratifying and executing the May 19, 2025 Agreement, funding implementation, and transfer or sale of Federal lands. Practically, it frames why Congress would ratify the Agreement: certainty, funding, and land‑and‑tax adjustments to implement operations tied to the Tribal Water Right.
Congress authorizes and directs Secretary to execute Agreement
The Act ratifies the Agreement except where it conflicts with the statute and directs the Secretary to sign it and any ministerial amendments needed for consistency. The Secretary may later approve modifications consistent with the Act so long as they do not require separate congressional approval under 25 U.S.C. 177. The section also makes clear that environmental compliance is required (ESA, NEPA, and other federal laws), that environmental review costs can be charged to the trust fund (with inherently federal functions remaining the Secretary’s responsibility), and that execution of the Agreement itself is not a NEPA major federal action.
Quantification, trust status, and administration of the 20,000 AFY right
This is the operational core: the bill confirms the Tribe’s Tribal Water Right to Produce/Use up to 20,000 AFY, places it in U.S. trust, protects it from forfeiture/non‑use doctrines, and declares its priority; it preempts the RAC with respect to that right and enables the Tribe to impose Tribal Production, Water, and Delivery fees governed by Tribal law and the Agreement. Administrative mechanics require the Tribe’s Water Ordinance to be amended (and approved by the Secretary) to allocate water to Allottees, create due process, and provide mechanisms for owners of fee land to apply for use. During the interim before Secretary approval, the Secretary administers certain Allottee rights.
Trust fund structure and withdrawal controls
The Secretary must establish the Agua Caliente Settlement Trust Fund and four named accounts. Mandatory deposits come from section 7, investment earnings are available for authorized uses, and withdrawals by the Tribe require either an approved Tribal management plan (per federal trust fund law) or an approved expenditure plan; the Secretary can enforce these plans and take judicial or administrative action to ensure compliance. Title and operation of infrastructure built with funds generally remain tribal, and the Tribe cannot make per‑capita distributions from the fund.
Mandatory Treasury transfers and cost adjustment mechanism
Congress (through the Secretary of the Treasury) is directed to transfer $500 million from the Treasury into the four trust accounts. The statute contains indexed adjustment language tied to a construction cost index and allows additional adjustments for market volatility as determined by the Secretary, with indexing measured from May 19, 2025 until deposit.
Conditions that must be satisfied to trigger rights and obligations
The Act will become enforceable only after a Secretary’s Federal Register notice certifies Agreement conformity with the Act, execution by all parties, full appropriation/deposit of trust funds, entry of a Final Decree by the federal court, and execution of required waivers/releases. The Act also includes an expiration backstop (default date) after which, if conditions are not satisfied, the Act (and its authorizations) lapses and unspent funds and property may revert or be returned subject to congressional approval.
Mutual releases with preserved carve‑outs
The Tribe and the U.S. (as trustee for Allottees) agree to broad waivers against claims described in the Agreement and the Act—covering many asserted water and related damages claims against CVWD/DWA and certain Tribe claims against the U.S.—but expressly reserve environmental and other specified claims (e.g., CERCLA, SDWA, CWA) and rights to enforce the Agreement. The waivers take effect on the Enforceability Date and toll relevant statutes of limitation between enactment and that date.
Preemption of county possessory tax and Tribal Tax framework
This section preempts Riverside County’s ad valorem possessory‑interest tax for taxable periods when the Tribe imposes a Tribal Tax on the same possessory interest, authorizes the Tribe to impose, collect, and distribute the Tribal Tax, and requires the Tribe to distribute proceeds to Other Public Agencies at least as they would have received under the county apportionment schedule, subject to a non‑increasing aggregate limitation. It permits delegation of administration to Riverside County via intergovernmental agreement and provides a limited tribal waiver of sovereign immunity to allow enforcement of distribution obligations.
Designated BLM parcels transferred into trust; conditions and restrictions
The Act identifies several large BLM parcels by legal description to be taken into trust for the Tribe on the Enforceability Date, notwithstanding certain federal monument or CDPA restrictions. Transfers are subject to valid existing rights, retention of improvements by prior holders, survey corrections, and an explicit prohibition on eligibility for class II or III gaming. Any water rights tied to those lands are held in trust for the Tribe but are not counted toward the quantified Tribal Water Right.
Sale of specified Facility Land to CVWD and cultural protections
The Secretary must appraise the Whitewater River Recharge Facility land and, if CVWD promptly offers to buy at fair market value and pays closing costs, convey the facility to CVWD. The appraisal costs fall on CVWD; sale proceeds go to a Federal Land Deposit Account. The section imposes stop‑work and consultation requirements for discovery of Tribal Cultural Resources on the Facility or adjacent lands, requires notification to tribal preservation officials and coroner for human remains, and gives the Tribe rights to inspect and decide treatment/reburial.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Agua Caliente Band of Cahuilla Indians — Gains a federally confirmed, trust‑held groundwater right (up to 20,000 AFY), $500 million in targeted settlement funding, newly trusted land parcels, and authority to set Tribal water fees and a Tribal possessory‑interest tax to fund tribal government and water infrastructure.
- Allottees (individual trust allotment owners) — Receive protections and an entitlement framework: water allocations governed by the Tribe’s Water Ordinance, access to Tribal Water Right supplies or allocations, and a statutory requirement to exhaust tribal remedies before some federal claims, with the Act stating congressional intent that Allottees’ benefits be at least equivalent to pre‑enactment status.
- Coachella Valley Water District and Desert Water Agency — Receive settlement certainty (waivers of certain claims), potential reimbursement from the Groundwater Augmentation Account for prior/ongoing augmentation investments, and a statutory path to acquire and operate the recharge facility land (CVWD purchase).
- Other Public Agencies (local taxing entities) — Are entitled to receive distributions from the Tribal Tax proceeds at least equivalent to what they would have received under the Riverside County tax apportionment schedule, providing predictability for local budgets (subject to statutory caps).
- Federal government (DOI/Secretary) — Gains a statutorily authorized, orderly framework to implement a long‑running dispute, consolidating settlements, specifying environmental compliance obligations, and avoiding prolonged litigation.
Who Bears the Cost
- U.S. Treasury / Federal budget — The Act mandates $500 million in transfers from the Treasury into the Settlement Trust Fund, with additional risk of cost adjustments tied to construction indexes and Secretary determinations for market volatility.
- Riverside County as a taxing and administrating entity — Faces a changed revenue base for possessory interests and the administrative choice to accept delegation to collect and distribute the Tribal Tax under intergovernmental agreement; county revenue timing and accounting will shift.
- CVWD — Must pay fair market value and conveyance costs to purchase the Facility Land if it elects to acquire it, and carries appraisement and closing costs; CVWD also remains exposed to operational responsibilities for infrastructure it owns or operates.
- The Secretary / DOI — Has new administrative and oversight duties (approving tribal ordinance amendments, approving withdrawal plans, enforcing expenditure plans, certifying the Enforceability Date, and overseeing NEPA/ESA compliance) and retains responsibility for inherently federal functions and certain review costs.
- Non‑tribal lessees, developers, and fee‑land owners on the Reservation — May face new taxation (Tribal Tax), Tribal water fees and delivery charges, and should expect to negotiate with the Tribe for water leases subject to the Tribe’s Water Ordinance and Secretary approval.
Key Issues
The Core Tension
The central dilemma is between finality and sovereignty: the Act seeks finality for water users and local governments by converting a negotiated settlement into enforceable federal law and large federal payments, while simultaneously expanding tribal sovereignty over water allocation, fee authority, land status, and taxation—a package that resolves many disputes but redistributes rights, revenues, and long‑term obligations in ways that create trade‑offs and implementation risks for tribal members, local governments, and the federal trustee.
The Act trades litigation uncertainty for a tightly circumscribed statutory structure—and that trade carries implementation friction. The Enforceability Date is a compound trigger: it requires execution of an amended Agreement consistent with the Act, a Final Decree by the federal court (from which no appeal remains), and full deposit of the statutory funds.
That sequencing creates timing risk—if funding or the Final Decree lag, the settlement and its waivers remain dormant and statutory expiration consequences (including reversion of unspent funds and voiding authorizations) are severe.
The bill’s preemption of local fees and transfer of possessory‑interest revenue to a tribal tax framework shifts local finance patterns and creates an enforcement puzzle. The Tribe must distribute proceeds to Other Public Agencies consistent with the county schedule, but the statute also limits the Tribe from distributing more combined revenue than those agencies would have received under state law, producing a reconciliation exercise that could invite litigation.
The Tribe’s limited waiver of sovereign immunity for enforcement of distribution obligations narrows remedies and centers federal court enforcement or intergovernmental agreements. Further, the Act preserves environmental causes of action under CERCLA, SDWA, and the Clean Water Act; retaining those claims while waiving many water‑rights claims may produce contested litigation over cause, timing, and damages attribution.
Trust fund mechanics and governance concentrate both power and responsibility with the Tribe but graft substantial Secretary oversight: withdrawals require approved Tribal management plans or expenditure plans, and the Secretary may sue or take administrative steps to enforce those plans. That creates a governance tension—tribal self‑determination in project selection and title vs. federal fiduciary oversight tied to massive federal funding.
Finally, the bill leaves multiple operational choices to subsequent agreement (title and OMR responsibilities for jointly funded projects, the details of tax delegation to the county), so much of the settlement’s daily impact will be governed by implementing contracts and the Tribe’s ordinances—each potential sources of new disputes if not precisely negotiated.
