Bank or Mine:

The Cadiz Desert-Water Project Turns on One Number No One Can Agree On

A Water Policy Series — July 2026

Introduction

On July 10, 2026, the U.S. Bureau of Land Management signed a decision three decades in the making: it granted Cadiz, Inc. the right-of-way to convert a defunct natural-gas pipeline into a water pipeline and begin construction, clearing the last major federal obstacle to pumping groundwater out from under the eastern Mojave Desert and selling it.¹ Cadiz’s stock rose. The company called it a milestone for a project it now brands the Mojave Groundwater Bank, promising up to 25,000 acre-feet of water a year to start and, someday, far more.¹ Conservation groups called it a water grab and an ethically compromised giveaway.² Both reactions are familiar, because this fight is old, and both sides have been making these exact arguments, in these exact words, since the 1990s.

Strip away the politics, though, and the whole thing comes down to a single number that neither side has ever managed to make the other accept: how fast the aquifer refills. Cadiz says the desert basin beneath its land recharges at about 32,000 acre-feet a year, enough to support decades of heavy pumping as a renewable supply.³ The U.S. Geological Survey and a run of independent scientists say the real number is a small fraction of that — estimates cluster between roughly 2,000 and 10,000 acre-feet a year, and some land near the bottom of that range.⁴ Cadiz wants to pump on the order of 50,000 acre-feet annually.³ Hold those figures next to each other, and the entire controversy resolves into one plain question, the question this piece is about: is Cadiz proposing to run a bank, drawing sustainable interest off a replenishing account — or a mine, hauling up fossil water that took the Pleistocene to accumulate and will not come back in any human timeframe? The permit does not answer that. The permit never has. And the remarkable thing about the Cadiz project is how far it has traveled, and how much money it has attracted, on a number that has never been settled.

I. The Number Under Everything

Everything else about Cadiz — the stock price, the federal loan, the tribal investment, the desert springs, the bighorn sheep — hangs on the recharge rate, so start there, because it is genuinely the crux, not a technicality. Groundwater in a closed desert basin like this one is, in the main, ancient. It seeps in over geological time from the surrounding mountains, a slow drip measured against the rainfall of a place that gets a few inches a year. The volume in storage can be enormous — Cadiz cites tens of millions of acre-feet in the Fenner Valley aquifer system — but that volume is not the question.³ The question is the flux: how much comes in each year to replace what you take out. A large balance you are drawing down faster than it refills is not a sustainable supply; it is a countdown, however long the count.

This is where a single word is doing an enormous amount of work. Cadiz used to call this the “Cadiz Valley Water Conservation, Recovery and Storage Project.” It now calls it the “Mojave Groundwater Bank.”¹ A bank is a precise and reassuring metaphor: you deposit, you earn interest, you withdraw the interest indefinitely, and the principal endures. That story holds only if recharge roughly keeps pace with extraction. If Cadiz’s 32,000-acre-foot figure is right, the metaphor is fair, and the project is, more or less, what it says it is. But if the USGS is right and recharge is closer to a few thousand acre-feet a year, compared to 50,000 pumped, then “bank” is not a description — it is a marketing term for its opposite. You would be withdrawing the principal itself, year after year, dressing a liquidation in the language of thrift. The independent science has leaned hard toward the lower numbers for two decades; Cadiz disputes it with studies of its own and points to monitoring and management safeguards it says would catch trouble early.^{3 4} I am not in a position to adjudicate the hydrology from a keyboard, and I will not pretend to. But the shape of the disagreement is the point: the two sides are not haggling over 10 percent. They are separated by a factor of five to twenty-five, which is the difference between a renewable resource and a one-time drawdown — and no permit issued in thirty years has required that gap to be closed before the pumping starts.

II. The Permit That Tracks the President, Not the Science

Here is the tell that this was never really settled on the merits: the science has stayed roughly put for twenty years while the permit has swung wildly, and it has swung in near-perfect time with who controls the Interior Department. Follow the sequence, because it is almost comic in its regularity. Cadiz first proposed selling desert groundwater in the 1990s; in 2002 the Metropolitan Water District of Southern California, the intended buyer, walked away over environmental, legal, and scientific doubts.⁵ In 2015 the Obama administration’s BLM ruled that Cadiz could not run its pipeline down a railroad right-of-way to dodge federal review — the project served no “railroad purpose,” so it needed permits and a full environmental study.⁶ In 2017 the Trump administration rescinded that finding, its solicitor lowering the bar so the project could slip through; in 2019 a federal judge called the reversal “incredibly broad” and unlawful.⁶ In the final days of 2020, Cadiz pivoted to an existing natural-gas pipeline with federal right-of-way already attached, and BLM approved the reuse; in 2022, under a new administration, the government asked to reconsider, and Judge George Wu vacated that approval for want of a real agency review.⁷ And now, in 2026, a BLM under new management again has said yes.¹

Blocked, cleared, vacated, cleared: four reversals, one underlying dispute, and through all of it the recharge science barely moved. What moved was the electorate. That pattern should unsettle anyone regardless of where they land on the merits, because it means the decisive factor in whether a desert aquifer gets drained has not been hydrology, or even law exactly, but the composition of a cabinet.

One person recurs throughout this history, and the record around him is worth setting down plainly, as facts rather than inference. Before entering government, David Bernhardt was a shareholder and lobbyist at the law firm Brownstein Hyatt Farber Schreck, which represented Cadiz; the company paid the firm $2.75 million and granted it 200,000 shares of Cadiz stock during his tenure there, and Cadiz’s president and chief executive from 2013 to 2023, Scott Slater, was a former Brownstein colleague.⁸ Bernhardt joined the first Trump administration’s Interior Department as deputy secretary in 2017 and became secretary in 2019; about a month after his 2017 swearing-in as deputy secretary, the department’s acting solicitor issued the opinion reversing Interior’s earlier position on the railroad right-of-way in Cadiz’s favor.⁸ In February 2025 Bernhardt joined the board of directors of Trump Media & Technology Group.⁹ That same year he launched a lobbying firm, the Bernhardt Group, which a Cadiz subsidiary — Fenner Gap Mutual Water Company — paid roughly $330,000 between the firm’s founding and April 2026 to lobby on the Mojave Groundwater Bank; Interior visitor logs show a Bernhardt Group lobbyist accompanied Cadiz’s chief executive on three visits to the department in 2025.⁹ Interior approved the pipeline on July 10, 2026. The Center for Western Priorities called the decision ethically compromised; no court or inspector general has ruled on the matter.² Those are the documented facts of the record, and this is the one inference I will draw from them: the project’s approvals have arrived when the Interior Department changed hands, not when the science changed.

None of this runs through Cadiz’s own board, on which Bernhardt has never sat: the company’s directors are drawn largely from California state government and finance, and its chairman and chief executive, Susan Kennedy, is a former chief of staff to Governor Arnold Schwarzenegger, a cabinet secretary to Governor Gray Davis, and a onetime communications director for Senator Dianne Feinstein — for years the project’s most prominent opponent.¹⁰

III. The Bank’s New Bankers

The newest chapter, though, is the one that breaks the old story, and it deserves to be told carefully rather than scored for points. For most of its life, the Cadiz fight had a simple cast: a corporation on one side, and on the other a coalition of environmentalists, desert communities, and Native nations defending the land and its water. That framing no longer holds because, in the last year, the project’s lead financier has become a tribe. The Lytton Rancheria of California committed up to $51 million to the Mojave Groundwater Bank — money structured as a loan convertible into an ownership stake — in what the company and the tribe accurately describe as the first major investment by a Native American nation in large-scale water infrastructure off its own tribal lands in United States history.¹¹

Take that seriously on its own terms first, because it is a genuine milestone. The Lytton Band of Pomo Indians spent much of the twentieth century as a case study in federal cruelty: terminated under the 1958 Rancheria Act, its land sold out from under it in 1961, its very existence as a tribe erased until a court restored recognition in 1991.¹² It rebuilt through gaming — the San Pablo Lytton Casino — and has spent the years since diversifying that revenue into property, agriculture, lending, and now water, exactly the kind of economic self-determination that federal policy spent a century trying to deny tribes.¹² A tribe deploying its own capital into Western water infrastructure is sovereignty in action, and it is not my place, or anyone’s, to tell the Lytton people their investment is illegitimate.

And yet the frame it breaks is worth naming precisely, because two true things now point in opposite directions. Lytton is a Pomo nation of Sonoma County — its homeland is the coastal north, some five hundred miles from the Mojave; it is an investor here, not an ancestral steward of this particular desert.¹² The tribes with deep ties to this land and these springs — the Chemehuevi, the Mojave, the Serrano peoples whose sacred waters the conservation groups invoke — are not party to the deal, and some stand among its opponents.⁴ So “the tribes” no longer resolves the question the way the old script assumed it would; Indigenous interest now sits on both sides of it, economic sovereignty on one and ancestral stewardship on the other, and neither cancels the other out. What the tribal investment changes is the project’s political and financial armor — it is far harder to cast it as a naked corporate raid when a historically wronged nation is a part owner. What it does not change is a single hydrological fact. Fifty-one million dollars of tribal capital, like the $194 million federal infrastructure loan the project has lined up, is a bet on the recharge number.^{11 13} It makes the number more consequential, not more correct. If the aquifer refills the way Cadiz says, that capital is patient and wise. If it refills the way the USGS says, the tribe and the taxpayer are helping finance a drawdown, and being early to a mine does not make it a bank.

IV. Moving the Shortage

There is one more shift worth catching, because it quietly changes what the whole project is for. When Cadiz began, the pitch was to slake thirsty Southern California cities — to pump water from the Mojave and send it west to Los Angeles through Metropolitan’s aqueduct.⁵ The pipeline BLM just approved runs the other way. The Northern Pipeline points toward the Colorado River and the Lower Basin, and the buyers now circling the project include agricultural districts in Arizona hunting for supply as the Colorado’s own shortage deepens.¹³ The rebrand to a “groundwater bank” fits this pivot: the sell is no longer just new water but stored water, a desert reserve to be drawn on when the river runs short.

Sit with the logic of that, because it is the desert-water version of borrowing from one maxed-out card to pay another. The Colorado River is over-allocated and shrinking; the response in this plan is to prop it up by drawing down a desert aquifer whose sustainable yield is itself in dispute. If the recharge skeptics are right, this does not add water to the arid Southwest so much as move a shortage around — trading a visible, monitored, endlessly litigated deficit on the river for a slower, quieter, harder-to-see deficit under the Mojave, and calling the transfer a supply. That might still be a reasonable trade in a genuine emergency, if the numbers were sound and the drawdown honest about being a drawdown. But it is being sold as the opposite of a drawdown, financed as a durable asset, and routed toward a basin so desperate it may not ask hard questions about where the water is really coming from or how long it can last. The springs of the eastern Mojave — Bonanza Spring and the seeps that keep desert bighorn alive through the dry months — sit downstream of the answer, and they cannot wait out an administration.⁴

Conclusion

So is Cadiz a bank or a mine? The honest answer, the one this whole review keeps circling back to, is that after thirty years, we still do not know authoritatively — and that is itself the scandal. This is not a case where the science is in, and the politics is merely ignoring it; the recharge rate is genuinely contested, Cadiz has its studies, and the USGS has its own, and reasonable caution would say you resolve a five-to-twenty-five-fold disagreement about sustainability before you sink the wells, not after. Instead, the project has advanced the other way around: securing the permits, the stock bump, the tribal equity, and the federal loan first, and leaving the one question that determines whether any of it is wise unanswered underneath. The permit is a political fact. The aquifer is a physical one. Thirty years and four administrations have never made them agree, and the approval signed on July 10 did not make them agree either — it just declared the political fact the winner and set the pumps running.

The trouble is that the physical fact gets the last word regardless, and it delivers it slowly, and only once. An aquifer does not announce that it was a mine and not a bank until the springs go slack and the water table drops past the roots and the wells and the desert has quietly changed state — by which point the capital has been spent, the water, if it was fossil, is gone, and there is no administration on earth that can vote it back into the ground. You find out what kind of account you had by hitting the bottom of it. That is a strange and reckless way to learn the most important number in the whole enterprise, and it is the way, barring a late reckoning, that this one is now set up to be learned.
