On January 20, 2025, a satellite passing over northern Utah caught a plume of dust rising off Farmington Bay and running south, past Salt Lake City, into Utah County. The state's own air quality division posted the image. What the satellite saw was the dry bed of the Great Salt Lake, lifted into the air and moving toward two million people.
These storms have a season now, spring and fall, and a shape that Kevin Perry can predict. Perry is an atmospheric scientist at the University of Utah who has spent the better part of a decade mapping the exposed playa by bicycle, pulling samples to find where the dust comes from. The wind arrives from the south ahead of a cold front and pushes the dust toward Layton, Syracuse, Ogden, and Brigham City, the northern towns with almost no air monitors, and then the front passes and the wind reverses and sends a few more hours of it back down into the Salt Lake Valley, where the monitors are.
The winter of 2026 made the season worse. It was one of the driest in state history, a year officials took to calling the "no-pack." By June, the lake had fallen to 4,191 feet above sea level, three feet above the all-time low it set in November 2022 and more than five feet below the elevation the state defines as healthy. A lake with a low level has more exposed bed than water, and the exposed bed is what the wind carries.
Why the lake is disappearing
Utah likes to blame the drought. The science does not.
The lake has been losing a slow argument with its own watershed for most of a century. Researchers at Utah State found that human consumption has depleted the lake's inflows by roughly 39 percent, lowering the water level by about 11 feet and erasing nearly half the lake's surface area. Wet years and dry years move the level up and down, hiding the pattern. Underneath the noise, the line runs steadily down, and it runs down because the water is spoken for before it ever reaches the lake.
A 2024 study in the journal Environmental Challenges traced where it goes. Human use consumes 62 percent of the river water that would otherwise flow to the lake. Farming accounts for about 71 percent of that. Of the farm water, four out of five acre-feet grow alfalfa and grass hay to feed close to a million head of cattle. The lake, in other words, is being drained to make cow food.
The water we ship away
Alfalfa and grass hay account for 68 percent of all the water Utah diverts each year. Growing a single ton of alfalfa takes about 1.38 acre-feet of water, close to what two Utah households use in a year. And the crop that consumes more of Utah's water than anything else is, in part, an export product.
How much of it leaves the country depends on how you count. By value, a 2020 analysis by University of Utah economist Gabriel Lozada, drawing on U.S. Census Bureau trade data, found about 29 percent of Utah's hay went overseas that year. By volume, the more intuitive measure, a Utah State University estimate puts the share lower: around 12 percent of the state's alfalfa in the peak years of 2019 through 2021, falling to under 6 percent by 2022. Either way, the water leaves with the bales. That overseas share represents an estimated 135,000 to 189,000 acre-feet of Utah water a year, water that will not return to the lake.
Follow the crop and the picture sharpens. Only about a third of the cattle feed grown in the Great Salt Lake basin stays in the basin. The rest ships to feedlots and dairies in Idaho and California, or overseas to Asia and the Gulf. China has been the largest foreign buyer, but its share has fallen sharply, from about 14 percent of Utah's alfalfa in 2019 to roughly 5 percent in 2024, and lower still after that. Saudi Arabia and the other Gulf states, which have restricted thirsty forage crops at home to protect their own water supplies, import them instead. They grow their cattle feed using someone else's water, and some of that someone is Utah.
The economics do not justify the cost. Utah produces about 1 percent of the nation's beef cattle and under 1 percent of its dairy. The basin's cattle-feed crops generated an estimated $162 million in 2021, about 0.07 percent of Utah's economy. Alfalfa nonetheless occupies roughly 35 percent of the state's irrigated acreage. A sliver of the economy drinks the largest share of the water and sends much of the resulting crop out of state.
The export market is also a warning against leaning on it. In early 2025, in the trade war, China's retaliatory tariffs on American goods reached 125 percent, and the alfalfa trade with China all but stopped. U.S. alfalfa shipments to China fell from about 83,000 metric tons in March to 50,000 in April, and total American alfalfa exports that April ran 37 percent below the year before. One trader put it plainly: China used to take up to 300,000 tons of Western hay a month, and by mid-2025 it was taking about a tenth of that. The hay piled up in the valleys. Prices fell. The water, of course, had already been spent.
Governor Spencer Cox owns and works an active alfalfa farm in Fairview, and he is the industry's most prominent defender, having called it "ignorant" to think cutting water to farms is the answer to the drought. In fairness, his fields lie outside the Great Salt Lake Basin, and he says he conserves on them without taking state subsidies. The scientists who study the lake keep arriving at the same uncomfortable place.
The Environmental Challenges team concluded that stabilizing the lake would take a 61 percent cut in the basin's alfalfa production, at a cost to farmers of about $97 million a year, a sum the state could cover for a fraction of what losing the lake would cost. The authors were careful to say farmers should be paid for the change, not blamed for it. That distinction has not made the recommendation any more welcome under the dome.
What blows east
The exposed lakebed holds arsenic, lithium, and a spread of heavy metals, left there by nature and by a century of mining and smelting around the lake. A 2024 study in Atmospheric Environment took Perry's playa samples into the lab and found the sediment more chemically reactive and more bioavailable than other dust upwind of the Wasatch Front. It also measured arsenic and lithium above the EPA's screening level for residential soil, though that comparison does not, by itself, establish a risk from breathing the dust.
A soil screening level describes a child eating dirt over years, not anyone inhaling it, and the arsenic figure in question sits below natural background: ordinary Salt Lake County soil exceeds it too. A 2025 paper in GeoHealth found that the most exposed group is children under six, who take in more dust relative to their size and swallow much of it, a pathway for which a soil benchmark is the right measure. Another 2025 study documented arsenic mobilization at the drying shoreline. In a controlled experiment, mice exposed to the dust developed lung inflammation.
The scale of the danger is genuinely contested, and the honest reason is that the air where it would matter most has barely been measured. A team at BYU studied a decade of urban air readings, found no correlation between the lake's size and city dust levels, and calculated that the metals reaching those monitors fall below the thresholds of concern.
But those monitors sit in the Salt Lake Valley, not in Layton, Syracuse, Ogden, or Brigham City, the northern towns the wind reaches first and where almost no one measures the air during a storm. Establishing a real inhalation risk would take exactly what the state is not collecting there: airborne concentrations, particle size, exposure duration, and dose. For now, the Wasatch Front meets the federal standard for large-particle dust. The catastrophe is a trajectory, not a measurement already taken, and the measurements that would settle it are the ones Utah is not making.
The trajectory points to Owens Lake. Los Angeles drained it a century ago, and its dry bed became one of the largest sources of dust pollution in the country. The cleanup there is projected to cost $3.6 billion, with no end in sight, because a dead lakebed has to be managed forever. The Great Salt Lake is more than ten times the size of Owens Lake, and the population living downwind of it is fifty times larger.
The harm would not be shared equally. A 2024 study in One Earth found that the dust falls hardest on Hispanic and Pacific Islander communities and that raising the lake would shrink that gap along with the dust. A University of Utah tool now lets anyone lower the lake on a map and watch the plumes reach the same northern towns that have no monitors to measure them.
What would stop it
The remedy is easy to state. Put more water in the lake.
The quantities are known. Ben Abbott, the BYU ecologist who has become the loudest voice on the lake, estimates it needs 500,000 to 800,000 acre-feet of extra water a year to stop shrinking, and about a million a year to return to health. His 2023 emergency report set a target river flow of 2.5 million acre-feet per year, the threshold above which the lake historically rises, and an order of operations to reach it. Cut waste first. Build new plumbing last, and only as much as conservation cannot supply.
The tools exist. Utah has spent five sessions building them. Farmers can now lease water to the lake without surrendering their water rights, paid at market value, with split-season options that let them keep farming part of the year. A 2026 policy guide from the University of Utah's S.J. Quinney College of Law named the three reforms that would matter most: streamlined water markets, steady funding, and urban conservation.
The last is the reform that Utah keeps refusing. Urban and suburban water use is now almost 27 percent of the basin's depletions, a share the state's 2026 Strike Team found rising as the population grows, and most of it goes onto grass. In the 2026 session, lawmakers passed a bill to speed water transfers to the lake, then killed bills that would have limited ornamental turf in new subdivisions and strengthened the price signals that reward water conservation. The plumbing to move water got easier. The demand that empties the rivers went untouched.
The two rescues
Two organizations have stepped into that gap, and the difference between them is the difference between two theories of how Utah saves anything.
The first is money. In the fall of 2025, after Cox announced the state would restore the lake before the 2034 Winter Olympics, Josh Romney convened Utah's business establishment and launched Great Salt Lake Rising. Romney runs a real estate firm and a mortgage company and is the son of the former senator. His coalition pledged to raise $100 million, meant to match a separate $100 million commitment from Ducks Unlimited, and by March 2026, it had secured about a third of that. The donors read like a directory of Utah wealth: the families behind Marriott hotels, Maverik gas stations, and the Miller sports empire, along with tech figures like Matthew and Tatiana Prince and the Ryan and Ashley Smith Foundation.
Romney is candid that his interest is partly personal. He worries about the dust reaching his children, and, along with his fellow developers, that families frightened by the air will sell and leave, taking his real estate market with them. His group's plan leans on engineering and philanthropy. It would redirect water that has been pooling for decades in the Newfoundland Basin under an old flood-control scheme, tear out the invasive Phragmites reeds that drink from the wetlands, and coax voluntary conservation from homeowners and farmers.
When the state moved to buy the defunct US Magnesium plant on the lake's south shore, Romney personally guaranteed the $30 million so the state could bid fast in bankruptcy court. He estimates the full rescue will cost around $3 billion, and about $500 million just to stabilize the water. His organizing frame is blunt: "This is not theoretical, this is math," he told a Deseret podcast, because the lake keeps falling in any year the snowpack is not far above average, and no one can count on that.
The second theory is pressure. Grow the Flow launched in October 2023 as a project of the nonprofit Conserve Utah Valley, led by Abbott, with a BYU ecologist as scientific director and a University of Utah law professor as policy director. It is not a fundraising campaign and posts no dollar goal. Its currency is organized people. Its stated aim is to build a public-action network of 100,000 Utahns, provide technical and legal support to lawmakers, and become the first community anywhere to restore a saline lake. Its scientific director, Rachel Wood, has put the core idea in five words: "we can't negotiate with water."
In practice, Grow the Flow's most visible work in 2026 was blocking a new straw before it reached the ground. The Stratos Project is a proposed data center in Box Elder County, backed by the investor Kevin O'Leary and the state's Military Installation Development Authority, sized at nine gigawatts, more than double the electricity the entire state uses at peak, and dropped into the Great Salt Lake basin, where every acre-foot is already claimed. Grow the Flow ran town halls, panels, and a press tour of the land, and helped drive nearly 4,000 formal protests against a single water-rights application. The landowner withdrew it. The Senate president demanded the project be reduced by three-quarters, and O'Leary cut its footprint from 40,000 acres to 20,000. At a May panel, a Box Elder grandmother named Brenna Williams stood up and talked about her grandchildren's asthma and gave the room fifteen reasons the data center was a mistake.
The contrast is the story. Great Salt Lake Rising is capitalized in dollars and built to redirect water and pull reeds without asking anyone to grow less. Grow the Flow is capitalized by citizens and built to change water law and stop new demand, and it is willing to name the thing the philanthropists route around. Abbott says out loud that Utah has to cut consumptive use, alfalfa included. Both want the same result. Only one of them keeps saying the word that makes the Legislature flinch.
What Utah's leaders should do now
The state has done real things. It has appropriated more than $300 million for the lake since 2022, created a Great Salt Lake commissioner, and struck a deal with Compass Minerals to return more than 200,000 acre-feet of water a year and hand back 65,000 acres of lakebed. In February 2026, the president entered, calling the lake an environmental hazard and posting "MAKE 'THE LAKE' GREAT AGAIN." He then requested $1 billion in his 2027 budget for a federal restoration program, and his EPA administrator laid out the split on the shore of Farmington Bay: $300 million to buy and lease water, $244 million for urban conservation, $190 million for engineering, and the balance for habitat, ecosystem work, and a wetlands settlement.
The billion dollars is a request, not a deposit. Congress has so far written about $14.5 million into House committee bills, a $10 million program secured by Representative Celeste Maloy plus $4.5 million added by Representative Blake Moore, none of it yet signed into law. Maloy, the only Utahn on House Appropriations, says the full sum will arrive, if it arrives, "over a series of years." The same budget that dangles the billion cuts the agencies that would spend it. It reduces the Bureau of Reclamation by 22 percent and the U.S. Geological Survey by 37 percent. The Geological Survey is the agency that monitors the dust.
That leaves a plain instruction. Do not spend the political capital of a federal promise as if the money were already here, and do not let the promise become a reason to do less at home. The state's own Strike Team reports that the lake has stabilized but remains below healthy levels, and that reaching healthy levels would require adding 800,000 acre-feet of inflow every year through 2055. That is not a rain problem. It is a decision about how much water Utah leaves in its rivers, made every session, in bills about turf, water markets, and the price of a lawn.
Abbott frames the deadline in language a conservative state should hear clearly. Fix this now, on Utah's terms, with Utahns paid to conserve. Or wait, and let the Clean Air Act and the Endangered Species Act do it later, on Washington's terms, with mandates instead of checks. The two wet winters that followed the 2023 alarm did not save the lake. They bought time, and then 2026 spent it.
On July 13, 2026, on a bus tour of the ranchland slated for the data center, a man named Val Anderson held up a photograph of his father standing in water at a spot near the lake that is now cracked and dry. Within living memory, the water was there. The question the photograph asks is whether it will be there for the grandchildren, or whether they will only know the wind that comes off the place where it used to be.
A note on corrections and updates
After this piece was published, Mike Miller of Mobile Air & Power Rentals raised several substantive challenges in the comments on LinkedIn. We looked into each one, found him right on the specifics, and have updated the article accordingly. We are grateful for the scrutiny. Good criticism makes reporting better, and we would rather correct in public than be quietly wrong. Here is what changed.
Alfalfa exports and the water shipped abroad. The original version stated that "29 percent of Utah's hay harvest by value leaves the country, most of it bound for China," and that the overseas share carried "close to a million acre-feet of Utah water abroad every year, roughly the amount the lake itself needs to recover." Those figures traced to a real source, a 2020 analysis by University of Utah economist Gabriel Lozada using Census Bureau data, but they were narrower than the framing implied. That 29 percent was measured by value in a single pre-tariff year.
By volume, the more intuitive measure, a Utah State University estimate puts Utah's overseas share closer to 12 percent of its alfalfa in the peak years and under 6 percent by 2022. China's share specifically has fallen sharply, from about 14 percent of Utah's alfalfa in 2019 to roughly 5 percent in 2024. And the water embedded in those exports is far less than we wrote: the same Utah State estimate puts it near 135,000 to 189,000 acre-feet a year, not close to a million, and not "roughly the amount the lake needs to recover." The section now reflects all of this, and we retitled it because "The water we ship to China" overstated a share that has been falling for years. What did not change is the point beneath it: the crop consumes most of Utah's water, much of which leaves the state, and the water is lost to the lake wherever the bales end up.
Arsenic and the soil screening levels. The original version stated that the lakebed dust held "arsenic and lithium levels above the EPA's residential soil standards," positioned as evidence of a health risk from breathing it. As Miller pointed out, a soil screening level does not establish an airborne risk. That benchmark is based on a child ingesting soil over years, not on anyone inhaling dust, and the arsenic level in question is below the natural background, so ordinary Salt Lake County soil exceeds it too. Establishing an inhalation risk requires measured air concentrations, particle size, exposure duration, and a dose calculation. The section now draws that distinction and reframes the real concern: not the soil number, but the fact that the most exposed communities, north of Salt Lake City, have almost no air monitoring, so no one has measured what they breathe during a storm.
Governor Cox's farm. The original version described Governor Spencer Cox as coming "from a farming family." Steve Ellis of Cydata Labs pointed out on LinkedIn that this understated a relevant fact: Cox does not merely come from farmers; he owns and actively works an alfalfa farm in Fairview, the very crop at the center of this story. He is right, and we have updated the passage to say so. In fairness to the governor, as noted in the piece, his farm lies outside the Great Salt Lake Basin, so it does not draw from the water that would reach the lake, and he says he conserves on it without taking state subsidies. The disclosure belonged in the article, and we thank Ellis for the catch.
We have left the article's central findings in place. The corrections tighten specific claims without touching the core: the lake is near record lows, most of the water that would refill it is used to grow cattle feed, and that water is lost to the lake regardless of where the crop is sold.
