The institution
What is the Conservation Bank?
A standing public buyer and accountant for voluntary, temporary, compensated, and verified reductions in Colorado River consumptive use.
The Bank would not purchase or permanently transfer the underlying water right. It would contract for a defined quantity of conserved consumptive use during a defined period and account for that water in protected system storage or another legally authorized reserve.
This structure builds on real precedents. Upper Basin pilot programs already use “temporary, voluntary, and compensated” conservation, and the Demand Management Storage Agreement already contemplates verification, conveyance-loss accounting, annual confirmation, and storage of up to 500,000 acre-feet if an Upper Basin demand-management program is approved.1
The compact
Six non-negotiable principles
- Participation is voluntary
- Water rights stay with owners
- Tribal sovereignty is respected
- Only real savings are paid
- Communities share the benefit
- Every acre-foot is public
From offer to reserve
How a transaction works
Contracts can support rotational fallowing, deficit irrigation where agronomically sound, crop switching, municipal efficiency, industrial process changes, reuse, leakage reduction, or permanent infrastructure. Each method needs its own approved measurement protocol.
The operating framework
Eight safeguards that make it work
Valid, recently used water
Eligibility begins with a valid water right or contract and a defensible history of consumptive use. The water must otherwise have been legally available and likely to be consumed during the contract period.
No injury and return-flow protection
The relevant state, Tribal, or federal authority reviews effects on other rights, return flows, groundwater, interstate obligations, and the environment before approval.
A weather-adjusted baseline
Baseline consumption uses multiple representative years and adjusts for weather, crop, acreage, system changes, and abnormal shortages. A claimant cannot be paid for water they would not have used.
Measurement, reporting, verification
Metering, remote sensing, crop and land records, diversion data, and return-flow models are combined under published protocols. Independent verification precedes final payment.
Pay for net system benefit
Credited volume equals reduced consumptive use minus lost return flow, conveyance loss, rebound, leakage, and an uncertainty reserve. Conservative accounting protects the public.
Temporary terms and recovery periods
Annual, multi-year, and option contracts are allowed, but repeated land idling triggers soil-health, weed-control, labor, and local-impact plans. Permanent transfer requires a separate public process.
Competitive, transparent pricing
Reverse auctions and scored solicitations reveal the price required for participation. Selection weighs cost, certainty, duration, location, equity, and community or environmental co-benefits.
Enforcement and public audit
Contracts include inspection rights, payment holdbacks, clawbacks for material overstatement, appeals, and penalties for fraud. Aggregated project and financial results remain public.
Shared authority
Governance designed for trust
No single state, sector, or federal agency should control the Bank.
Governing board
Voting seats should include the seven Basin states, Basin Tribal Nations through representatives selected by Tribes, the U.S. Department of the Interior, and Mexico where treaty mechanisms permit. Non-voting technical seats should represent agricultural, municipal, environmental, power, and rural-community expertise.
Independent bodies
- Science and Accounting Panel: approves protocols, uncertainty discounts, and annual water budgets.
- Tribal Advisory Council: has early, continuous authority over rules affecting Tribal water, data, and sovereignty—not consultation after decisions are drafted.
- Inspector General and external auditor: investigate fraud, verify finances, and audit a statistically meaningful project sample every year.
- Community Impact Office: tracks employment, tax-base, food-production, and environmental effects and administers mitigation funding.
- Appeals officer: provides timely review independent from procurement staff.
Existing Upper Basin demand-management rules show why joint approval and accounting matter: implementation requires agreements on verification, conveyance, storage, and releases, with state, commission, and federal roles.1
A conservative planning case
Start by planning for up to $10,000 per acre-foot.
At that planning allowance, one million acre-feet costs up to $10 billion; two million costs $20 billion; and four million costs $40 billion.
| Verified annual savings | At $10,000/AF | Per 40M people |
|---|---|---|
| 500,000 acre-feet | $5 billion | $125/person/year |
| 1 million acre-feet | $10 billion | $250/person/year |
| 2 million acre-feet | $20 billion | $500/person/year |
| 4 million acre-feet | $40 billion | $1,000/person/year |
Arithmetic divides total program cost by approximately 40 million municipal users for scale; it is not a proposed household fee. Administrative costs and the overlap between municipal users and taxpayers mean actual incidence would differ.
Why $10,000 is a planning allowance, not a guaranteed price
Recent short-term federal system-conservation agreements have commonly paid roughly $330–$400 per acre-foot, and a Lower Basin pilot reported an average near $170 per acre-foot.23 Those prices are evidence that many near-term savings may be acquired far below $10,000.
But a durable Basin-wide institution must budget for harder-to-acquire marginal water and more than a one-year forgone use: infrastructure, monitoring, return-flow protection, transition assistance, community impacts, Tribal capacity, environmental compliance, multi-year options, and enough incentive for broad voluntary participation. The Bank should obtain the least expensive high-confidence savings first through competitive bids and never pay the ceiling when lower bids are available.
Recommended rule: Congress authorizes a maximum all-in planning envelope of $10,000 per verified acre-foot. The Bank publishes the actual conservation payment, verification cost, community benefit, and total all-in cost separately for every program round.
The value proposition
Why should we be willing to pay?
Because shortage has a price too
Water supports homes, farms, Tribal communities, food production, hydropower, businesses, habitat, and recreation. Reclamation reports approximately 40 million municipal users, 5.5 million acres of farmland, and more than 8 billion kilowatt-hours of annual hydropower.4 A planned conservation purchase is an insurance premium against emergency curtailment, litigation, stranded infrastructure, and economic disruption.
Because voluntary water should not be priced like confiscated water
A low payment may cover a crop’s short-term net return but ignore workers, suppliers, soil recovery, local taxes, food production, uncertainty, and the option value of reliable water. Paying enough to make participation genuinely attractive is fairer and more dependable than expecting one region or sector to absorb the system’s risk.
Because the ceiling is not the average
A $10,000 authorization lets the Bank reach high-value or capital-intensive projects when necessary. Competitive procurement, volume targets, and public reporting should keep the portfolio average well below the ceiling whenever the market can deliver credible savings for less.
Because durable infrastructure keeps producing value
Some expenditures buy more than a single year of water: canal automation, measurement, reuse, leak repair, soil improvements, crop transitions, and municipal retrofits can produce benefits over many years. Those projects should be evaluated on annualized lifetime cost per verified acre-foot, not the first-year check alone.
A community dividend
The communities that conserve most should gain more than a check.
A permanent Community Trust Fund should invest in the towns, Tribal communities, irrigation districts, and rural counties that carry the largest economic and civic burden when water use declines.
Direct conservation payments compensate the participating water user. They do not automatically replace wages at a farm supplier, enrollment and revenue at a school, patient capacity at a rural hospital, sales and property taxes, or the economic activity that moves through an agricultural community. The Trust Fund addresses that second circle of impact.
A protected source of money
The Community Trust Fund should receive a federal capitalization appropriation plus an automatic community dividend attached to Bank acquisitions. As a proposed starting rule, the annual deposit associated with a participating area should equal the greater of 10% of its conservation payments or $500 per verified acre-foot. That deposit must be additional to—not deducted from—the water user’s negotiated payment.
The Bank board should revisit the formula after an initial three-year pilot using independently measured employment, revenue, and public-service effects. Congress should set a minimum floor so community funding cannot be eliminated during annual appropriations or redirected to water purchases.
Local priorities, durable investments
Tourism and economic diversification
Trail and river access, cultural tourism, downtown renewal, small-business grants, workforce training, broadband, and locally chosen industries that create year-round income.
Infrastructure
Drinking-water and wastewater systems, roads, bridges, broadband, public buildings, energy resilience, irrigation modernization, and deferred maintenance.
Schools and hospitals
Teacher and clinician recruitment, facilities, transportation, career programs, telehealth, emergency services, and other capacity threatened by a shrinking local economy.
Tax-base stabilization
Time-limited replacement of demonstrable public-revenue losses so essential services do not collapse while new economic activity comes online.
Who decides
Each eligible area should establish a local Community Trust Council with public meetings and seats for local and Tribal government, schools, health care, workers, water users, small businesses, and residents. At least half of voting members should live in the affected area. The council writes a five-year resilience plan and selects grants within federal eligibility rules; the Bank verifies compliance but cannot substitute its own projects for locally adopted priorities.
How funds are allocated
Formula grants should provide predictable base funding. Competitive grants can support larger regional projects. The proposed formula weighs:
- 50% water contribution: the area’s verified conserved consumptive use.
- 25% economic exposure: documented effects on employment, income, agricultural support businesses, and local revenue.
- 25% community vulnerability: fiscal capacity, remoteness, health and education access, and persistent economic disadvantage.
Guardrail: Trust money cannot purchase water rights, subsidize speculative development, replace the participant’s conservation payment, or be conditioned on permanent relinquishment of water. Unspent principal remains dedicated to the affected community.
Paying together
A diversified funding stack
No single user class should carry a Basin-wide public benefit. Congress should capitalize both the water-acquisition account and the legally separate Community Trust Fund with multi-year authority, then combine:
- Federal appropriations for interstate stability, treaty obligations, Tribal participation, national economic benefits, and initial Trust Fund capitalization.
- Basin-state contributions tied to agreed formulas rather than annual political bargaining.
- Municipal and industrial reliability charges with affordability protections for low-income households.
- Hydropower and recreation contributions only where consistent with law and operational obligations.
- Voluntary philanthropic or corporate contributions that buy no governance control, preferential grant access, or water claim.
Trust Fund principal, earnings, and community-dividend deposits should be held separately from water-acquisition money and remain available across fiscal years. Tribal program funds should be available for technical capacity and infrastructure before requiring conserved-water delivery.
Public accountability
The annual scorecard
The Bank should publish machine-readable project data and an independently audited annual report showing:
- Offers received, accepted, rejected, and withdrawn by region and project type.
- Baseline, gross savings, return-flow adjustment, conveyance loss, uncertainty reserve, and credited net savings.
- Payments to participants, verification and administration costs, and Community Trust deposits shown separately.
- Every Trust Fund grant, recipient, purpose, milestone, administrative cost, and measured community outcome.
- Reservoir or reserve accounting showing where conserved water is held and under what legal authority.
- Effects on rural employment, public revenue, farm production, Tribal participation, ecosystems, schools, health care, and vulnerable households.
- Audits, disputes, clawbacks, nonperformance, and methodology changes.
