Reclamation released its Final EIS for post-2026 Colorado River operations on July 31, 2026, and the coverage since has leaned toward crisis: the largest proposed water cuts in the river’s history, governors calling terms unacceptable and unrealistic, litigation threats from more than one state. Read closely, though, the document is something narrower and more useful to a lender than a crisis headline: a framework that sets the pace at which real numbers arrive, not the numbers themselves. What it actually says, and what it means for tracking collateral over the life of a loan, is worth walking through carefully.
What a FEIS Is, and Isn’t
- The FEIS is a NEPA compliance document. It concludes a three-year process and over 18,000 public comments. It designates a preferred alternative among five that Reclamation analyzed, and sets the outer sideboards for the next decade of operations.
- It is not an allocation order. No water agency, district, or right holder has a specific number yet. Those numbers come later, from a different document.
- Two documents are still ahead: a Record of Decision, then a biennial Operating Plan. The first Operating Plan covers 2027-2028 and will carry the real, district-level numbers lenders need.
What the FEIS Actually Says
The preferred alternative sets sideboards, not fixed rules. Annual Lake Powell releases can run between 5.0 and 12.0 MAF depending on hydrology. Lower Basin shortages start once they exceed average annual evaporative and system losses at and below Lake Mead, and can scale up to 3.0-3.5 MAF in the driest years. Both reservoirs can bank conserved water for later use, up to 8.0 MAF in Powell, 3.0 MAF in Mead, and Upper Basin states can voluntarily conserve up to 200 KAF/yr, with that water credited to storage in Powell rather than lost to the system.
Two structural features matter more than the headline numbers. First, the FEIS builds in explicit accounting of unused and undeveloped quantified Tribal water rights, a category of demand that has been effectively invisible in prior operating guidelines and that could pull additional supply out of the system as Tribal water use develops. Second, releases shift to a run-of-river operation, tracking inflow rather than a fixed schedule, once Lake Powell falls to 3,510 feet. That’s a real infrastructure threshold, not a policy choice.
Reclamation’s own modeling gives a sense of how shortage gets divided once it’s triggered. For a representative 1.5 MAF Lower Basin shortage, the modeled split is roughly 760 KAF for Arizona, 440 KAF for California, 50 KAF for Nevada, and 250 KAF from Mexico’s treaty allocation. That lopsided split isn’t new policy. It follows directly from the 1968 Congressional deal that built the Central Arizona Project: CAP water, created after 1968, is cut before California’s senior 4.4 MAF apportionment is touched. Every operating plan under this framework will inherit that same priority structure.
What’s Actually Coming Next
- Record of Decision: formalizes the preferred alternative as the governing framework.
- 2027-2028 Operating Plan: the first plan under the new framework, expected within weeks. This is where district-level numbers appear.
- Reissuance every ~2 years through 2036, unless the seven states reach a longer consensus agreement. Collateral assumptions get revisited on a two-year clock, not a ten-year one.
- Litigation risk is on the table, not off it. Nevada has said it will fight outcomes it sees as unreasonable. Arizona is pressing for the Lower Basin’s own proposal over the federal framework. A ruling either way moves the numbers again.
How the States Are Actually Reacting
- Arizona: Central Arizona Project’s own statement is measured and forward-looking. CAP says the FEIS contains legal flaws and misstates Arizona’s rights, but expects the 2027-2028 Operating Guidelines to better reflect the Lower Basin proposal. CAP points to conserving nearly 900,000 acre-feet last year, Arizona’s lowest Colorado River use in roughly 35 years.
- Nevada: holds 1.8% of Colorado River rights and faces the smallest absolute cut of the three Lower Basin states, capped at 210 KAF/yr in dry years. Gov. Lombardo calls the reductions unrealistic and has signaled Nevada will contest the outcome.
- California: the calmest voice on the record. JB Hamby and IID call for enforceable reductions from every water user and point to the Law of the River as the fallback if no agreement is reached, protecting senior rights.
- Upper Basin (CO/UT/WY/NM): a measured joint statement. Encouraged that guidelines better reflect actual supply, but clear that nothing can be assessed until agreements are finalized and implemented.
- Tribes and conservation groups: the pre-FEIS coalition of Tribal and conservation interests pushed for real Tribal participation and stronger environmental protections in the final framework. Formal FEIS-specific statements from most of the 30 Basin tribes are still coming as governments finish reviewing the document, worth watching over the next few weeks for how Tribal water claims get treated in the 2027-28 plan.
Why This Hits Ag Collateral Differently
Row-crop and forage ground, alfalfa included, can idle a season and absorb a cut through fallowing, which is exactly why alfalfa has been a go-to crop in prior Colorado River conservation deals. Permanent plantings, orchards and vineyards, can’t. A multi-year reduction in reliable Colorado River deliveries doesn’t just lower a borrower’s revenue for a season. It can impair the underlying value of the planting itself, usually a meaningful piece of the collateral base on ag paper. That distinction matters when the 2027-28 numbers land, because the same MAF reduction can carry very different credit consequences depending on what’s actually growing on the collateral.
Bottom Line
- This is not a one-time shock to underwrite once and file away. Collateral water reliability moves on a two-year cadence for the life of the loan. It is not fixed at origination.
- Lenders get exposed when they have no way to see collateral water risk change between now and the next Operating Plan, whether or not they hold Colorado River paper directly.
- Diligence going forward means tracking parcel- and portfolio-level water exposure continuously, not only at renewal. That tracking capability, not the FEIS itself, is what separates portfolios that get surprised from portfolios that don’t.
Put concretely: a CAP-dependent parcel underwritten today carries a different water-reliability profile than the same parcel after the 2027-28 Operating Plan lands, and a different profile again at the next reissuance in 2029. A lender with parcel-level tracking sees that shift coming and can price or structure around it. A lender without it finds out at the next appraisal, or worse, at default.
Where to Point Portfolio Monitoring
| Group | FEIS Sideboard | Monitoring Priority |
|---|---|---|
| AZ / CA / NV (Lower Basin) | Mandatory sideboard: up to 3.0 MAF cut over the coming decade. District-level numbers land in the 2027-28 Operating Plan, not this FEIS. | Track CAP-dependent and junior-priority collateral now. The 2027-28 numbers then update a known baseline instead of arriving cold. |
| CO / UT / WY / NM (Upper Basin) | Voluntary target only: up to 200 KAF/yr (~5% of 3.75 MAF annual use). No mandatory reduction under this sideboard. | Lower mandatory exposure. Monitor uptake, the 2023-24 pilot delivered roughly half its funded target. |
| California (within Lower Basin) | State officials point to cuts as the lowest since 1949 despite service population growth to 19 million. Final numbers still pending. | Favorable relative position. Confirm at each reissuance rather than assuming it holds for the full ten years. |
| Hydropower / Recreation (Powell & Mead) | Reservoirs at driest levels since 1957. Releases could run as low as 5.0 MAF/yr under the sideboards. | Track for regional power-cost and recreation-economy collateral, even where the exposure is indirect. |
Where This Leaves Ag Lenders
The FEIS doesn’t hand any lender a number to underwrite around, and it isn’t supposed to. What it hands over is a schedule: a Record of Decision, then a 2027-28 Operating Plan, then a new plan every two years through 2036, each one capable of shifting the water-reliability profile of Colorado River collateral. Portfolios that treat this as a settled fact from July 2026 will be wrong by the next reissuance. Portfolios that track it on the same two-year clock the federal government is now using will not be.
The cost of getting this wrong isn’t abstract. It shows up as a collateral value the lender didn’t see coming, a covenant breach traced back to a water cut nobody flagged at underwriting, or a permanent-planting loan that loses its asset before anyone updates the file. None of that requires the FEIS to be wrong or dramatic. It only requires a portfolio that isn’t watching.
Agcor tracks that exposure at the parcel and portfolio level. When the 2027-28 Operating Plan lands, you’ll already know how it affects your book instead of scrambling to find out. Work with us and see your collateral risk across all seven states before the numbers force the question. Let’s discuss what it looks like for you.
