What the ground held

Map: Cedar Valley agricultural landscape before land assembly

Cedar Valley sits in the low basin between the Oquirrh Mountains and the Lake Mountains in western Utah County, roughly thirty miles south of Salt Lake City. Before the first hyperscale tenant broke ground in 2021, the valley floor supported dryland wheat, alfalfa under irrigation from the Cedar Valley basin aquifer, and the close-grazed sagebrush range that transitions to high desert at the valley’s western margin.¹ The farms were small by Great Plains standards, running from a few dozen acres to several hundred, and the families who worked them were, with very few exceptions, members of The Church of Jesus Christ of Latter-day Saints who had settled the valley in the second half of the nineteenth century.²

The agricultural settlement of Cedar Valley followed the pattern the Church directed across the Intermountain West from the 1850s onward: cooperative irrigation works built under ecclesiastical supervision, farms platted on the grid survey, and wards organized simultaneously as religious congregations and civic bodies. Cedar Fort, the oldest town in the valley, was established in 1858 as a fortified settlement during the period of conflict between Church settlers and federal forces; it survives today as an unincorporated hamlet of roughly four hundred residents.¹ Fairfield, three miles to the south, was home to Stagecoach Inn, a Pony Express and stage stop from 1858 that the state now operates as a historic site. The two communities represent the original European settlement layer of Cedar Valley, and both predate Eagle Mountain City, the rapidly growing suburb that the Utah County portion of the valley incorporated in 1996.

The displacement this essay documents does not resemble the displacement the atlas records in Chávez Ravine, Boxtown, or Overtown. No family received a condemnation notice. No neighborhood received a “blight” designation. The valley’s agricultural families sold their parcels to land-assembly brokers at prices that reflected the hyperscale premium rather than agricultural value. That distinction matters, and the atlas names it plainly. The loss documented here is not of homes or civic institutions in the sense that redevelopment clearance destroyed them; it is the loss of a working agricultural landscape, a groundwater column, and the way of life that both sustained. The mechanism is market assembly rather than eminent domain. The scale and the permanence are the same.

The second community layer in Cedar Valley is older than the Mormon settlement by several thousand years. The Goshute people, who speak a Numic language related to Ute and Paiute, have occupied the Great Basin west desert since before the current millennium.³ Two federally recognized tribal nations hold modern sovereignty in the territory surrounding Cedar Valley. The Confederated Tribes of the Goshute Reservation govern a reservation in White Pine County, Nevada, and Juab County, Utah. The Skull Valley Band of Goshute Indians holds a 17,000-acre reservation in Tooele County, approximately thirty miles west of Eagle Mountain, in a basin whose hydrology connects through the same aquifer system that Cedar Valley feeds.¹ Neither the Confederated Tribes nor the Skull Valley Band relinquished water rights in the Cedar Valley basin when the federal patents were issued to Mormon settlers in the nineteenth century. Indigenous claims to Great Basin water predate the 1848 Treaty of Guadalupe Hidalgo, the 1869 completion of the transcontinental railroad, and every subsequent state water-law compact. The hyperscale land assembly that began in 2019 triggered no government-to-government consultation with either tribal government, a failure this essay records without minimizing.

The valley’s groundwater drew agricultural settlers in part because the Cedar Valley basin recharges relatively quickly by Great Basin standards, fed by winter precipitation on the Oquirrh and Lake Mountain flanks.¹ That recharge rate sustained alfalfa under irrigation for over a century. The Utah Geological Survey published a basin-flow model that documents, in quantitative terms, the relationship between pumping depth, seasonal recharge, and the baseflow that moves through the Jordan River corridor into Utah Lake and from there into the Great Salt Lake.¹ The survey’s model classified the basin as stressed under pre-hyperscale conditions; the data-center draw that began with Meta’s Phase 1 construction in 2019 and 2020 entered a system that was already running on a thin margin.

How the land assembly happened

Map: Meta, Google, QTS, and Tract land assembly in Cedar Valley

Meta acquired its first Cedar Valley parcels around 2019, before the company had announced any Utah data-center intention publicly.⁴ The acquisition used standard real-estate intermediaries who purchased parcels from individual landowners without disclosing the end buyer. Eagle Mountain City, which had been growing at suburban speeds since the late 1990s, was receptive to industrial-zone development that promised large property-tax revenue and a small residential footprint. The city amended its general plan to create a Regional Technology Innovation overlay district that provided by-right industrial approvals for data-center uses, removing the project from discretionary land-use review.⁵

Meta’s Phase 1 building opened in 2021 on a 193-acre parcel that the company subsequently expanded to a 970-acre campus.⁴ The campus’s water consumption in 2024, as disclosed under environmental reporting requirements, reached approximately 35 million gallons for the year. Expressed as a daily average, that figure is roughly 95,900 gallons per day.² Eagle Mountain City kept the figure confidential under a nondisclosure agreement with Meta while the environmental disclosure process remained pending; Grist’s 2024 investigation, drawing on state environmental records released after the disclosure deadline passed, brought the number into public view for the first time.

Google followed. Dgtl Infra’s industry coverage documents a 300-acre Google campus under development in Eagle Mountain, also served by Rocky Mountain Power and also sited on former agricultural ground immediately adjacent to the Meta campus.⁶ QTS Data Centers, a real-estate investment trust acquired by Blackstone in 2021, assembled over 100 additional acres in the same corridor. Tract, a data-center developer that announced its Eagle Mountain acquisition in late 2024, reported a 668-acre parcel with a 400-megawatt target and a 2028 in-service date.⁷ Together, the four operators assembled approximately 2,000 acres of former agricultural and sagebrush-range ground in a single county corridor.

The transmission infrastructure to serve that load does not yet exist in its final form. Rocky Mountain Power, the PacifiCorp subsidiary that serves the Wasatch Front, holds Utah’s vertically integrated monopoly franchise. The company sets industrial rates through proceedings before the Utah Public Service Commission, and residential customers have limited statutory protection against cost-shifting when the commission grants favorable industrial tariffs.⁸ New transmission easements for the Tract 400-megawatt build will cross Cedar Valley ranch land. No public authority had yet mapped the easement corridor as of April 2026, but the precedent for similar Rocky Mountain Power transmission corridors in the region is condemnation under the utility’s right-of-eminent-domain authority when voluntary negotiation fails.

The financing structure for the Eagle Mountain build relies in part on Utah’s economic-development incentive programs. Eagle Mountain City’s by-right Regional Technology Innovation overlay is itself an incentive: it removes public review costs and timeline uncertainty that, in other municipalities, give adjacent landowners and community organizations leverage to negotiate community-benefit agreements. Utah does not require community-benefit agreements as a condition of economic-development tax incentives, and no community-benefit agreement has been negotiated for any of the four Eagle Mountain campuses as of the date of this writing.

The Utah PILOT framework, under which industrial users pay payments-in-lieu-of-taxes rather than standard property-tax assessments during construction and early operation phases, reduces the revenue Cedar Valley’s taxing districts capture during the years when transmission and road infrastructure costs are highest.⁸ The structure is not unique to Utah; the Cheyenne cases in Wyoming and the Kuna cases in Idaho use analogous frameworks. In each case the municipality absorbs the infrastructure cost and the incentive during the build phase, and the utility absorbs the transmission investment cost, while the residential ratepayer base and the county property-tax base underwrite both.

What the water carries away

Map: Cedar Valley Basin, Jordan River corridor, and Great Salt Lake

The Great Salt Lake reached its recorded low elevation of 4,188.5 feet above sea level in November 2022, roughly eleven feet below the twentieth-century average and the lowest point since surveyors began keeping records in 1847.⁹ At that elevation the lake had lost approximately two-thirds of its historical surface area. The shrinking exposed lakebed contains arsenic, mercury, and fine-particulate mineral dust; wind events carry the dust across the Wasatch Front into the Salt Lake Valley, where it exceeds federal air-quality standards for particulate matter 2.5 micrometers in diameter.⁹ The lake’s brine shrimp and brine fly populations, which sustain roughly 10 million migratory birds annually on the Pacific Flyway, declined in direct proportion to the salinity increase that the low elevation produced.

The hydrological chain that connects Cedar Valley to the Great Salt Lake runs as follows. Cedar Valley groundwater discharges to surface flow and subsurface baseflow that moves north and east into Utah Lake, the freshwater lake twelve miles north of Eagle Mountain at the base of Mount Timpanogos.¹ Utah Lake drains north through the Jordan River, which runs forty-four miles through Salt Lake County before emptying into the Great Salt Lake’s south arm. The Utah Geological Survey’s Cedar Valley basin model documents that sustained groundwater withdrawals reduce the baseflow that reaches Utah Lake and therefore reduce the inflow that the Jordan River contributes to the Great Salt Lake.¹

Data-center cooling in an arid climate consumes water in two ways. Direct evaporative cooling uses water in the cooling tower and vents it as water vapor, a net consumption that does not return to the local groundwater column. Return-flow reduction is the second mechanism: agricultural irrigation, even inefficient flood irrigation, returns a portion of applied water to the groundwater column through percolation, and that return flow contributes to aquifer recharge. When a farm converts to an impervious data-center pad, the return-flow contribution ends permanently.² Both mechanisms reduce the Cedar Valley basin’s contribution to downstream flows, and both are present in the Eagle Mountain cluster simultaneously.

The Utah Legislature established the Great Salt Lake Strike Force in 2022, charged with developing a plan to restore the lake to a target elevation of 4,200 feet above sea level, the threshold the Utah Rivers Council’s 4,200 Project uses as its organizing target.⁹ The Strike Force issued its initial report in 2023. The report identified agricultural diversion reduction as the largest single source of recoverable inflow, which is accurate on volumetric grounds: irrigation diversions account for roughly 63 percent of consumptive use in the lake’s watershed. The report gave substantially less attention to the emerging hyperscale-data-center sector as a growing consumptive use, a gap the Utah Rivers Council has documented in its subsequent submissions to the Legislature.

The 2023 legislative session did not produce binding legislation requiring data-center operators in the Great Salt Lake watershed to meter and disclose water consumption. Eagle Mountain City’s confidentiality agreement with Meta was a legal consequence of that gap: without a state disclosure requirement, the city’s economic-development interest in protecting a corporate partner’s operating data prevailed over the public’s interest in understanding the basin’s water budget. The state’s treatment of data-center water as a private commercial datum while treating agricultural diversion as a public record produces a structural asymmetry that benefits the hyperscale sector at the expense of the lake’s water balance.

Who is fighting and what the ground holds

Map: Organizing geography: Utah Rivers Council, Jordan River corridor, and Great Salt Lake

The Utah Rivers Council, founded in 1994, has served as the primary scientific and legal advocate for Great Salt Lake restoration for three decades. The council launched the 4,200 Project to give the legislature and the public a single, legible target for the lake’s recovery: 4,200 feet above sea level, roughly eleven feet above the 2022 record low, the level at which the brine shrimp and brine fly ecosystems stabilize and the mineral-dust exposure drops below federal thresholds.⁹ The council launched a Great Salt Lake Waterkeeper in 2025, adding a formal legal-standing capacity to its existing scientific and policy work. The Waterkeeper designation, under the Waterkeeper Alliance framework, provides standing to file Clean Water Act citizen suits on behalf of the lake’s ecological interests.

The council’s 4,200 Project addresses agricultural diversion as the primary lever because agriculture is the primary volume. The council has been careful not to treat agricultural diversion as the only lever, and its most recent legislative submissions have named data-center consumption explicitly as a growing category that existing water-disclosure law does not cover.⁹ The connection between Cedar Valley groundwater, Jordan River baseflow, and lake elevation is not a hypothesis; the Utah Geological Survey’s basin model quantifies it. The council’s work has translated that quantification into a policy argument the legislature has not yet accepted.

The Alliance for a Better Utah operates on the transparency and ratepayer dimensions of the same landscape. The alliance’s method is to use the Utah Public Service Commission’s rate-case proceedings as a venue for surfacing data that utilities and their large industrial customers prefer to keep out of the public record.⁸ Rocky Mountain Power’s large industrial customer tariff for data-center accounts is set in commission proceedings that are formally public but practically opaque to residential ratepayers who lack the resources to participate. The alliance files comments, requests discovery, and publishes plain-language summaries of rate-case outcomes that allow Cedar Valley residents and the broader Wasatch Front public to understand what industrial pricing concessions cost the residential base.

Bridgerland Audubon, the chapter of the National Audubon Society serving northern Utah and the Bear River watershed, has documented Great Salt Lake’s bird-habitat decline with breeding-bird surveys that the National Audubon Society’s Great Salt Lake program coordinates.⁹ Bridgerland Audubon is not scaffolded as an organizer in the atlas as of April 2026; the Wave 6 integration agent should evaluate whether the organization warrants its own stub in content/organizations/.

The Skull Valley Band of Goshute Indians holds water rights in the sub-basin that abuts Cedar Valley. The band’s governing council has not, as of April 2026, filed formal legal challenge to the Eagle Mountain water withdrawals, but the hydrological connectivity between the Cedar Valley aquifer system and the Tooele County sub-basins is documented in the Utah Geological Survey record.¹ Any future water-rights litigation over Cedar Valley drawdown will necessarily engage Goshute senior-priority claims under the prior-appropriation doctrine Utah state law applies. The prior-appropriation framework assigns water rights by date of appropriation; Goshute water uses predate every state appropriation in the basin by centuries, even if the federal reserved-rights doctrine that would formalize that priority has not been litigated to judgment.

The Cedar Valley agricultural community that sold parcels to the data-center land-assembly intermediaries has not organized a collective resistance of the kind the Cabrillo Village farmworkers organized in Ventura County. The Cabrillo case, documented in this atlas’s Ventura County essay, involved a cooperative purchase in which farmworker residents bought their labor camp from the grower landowner rather than accept displacement; the purchase required years of tenant organizing, legal support from California Rural Legal Assistance, and a sympathetic grower who was willing to structure a sale to the cooperative. Cedar Valley’s sellers were landowners rather than tenants, and their position at the moment of sale was fundamentally different: they could accept the hyperscale premium and exit on their own terms, while Cabrillo’s residents had no alternative to eviction if the cooperative purchase failed. The structural difference does not diminish what Cedar Valley lost; it explains why the resistance took the form of water-rights and ratepayer advocacy rather than land-defense organizing.

The atlas records as survived: Utah Rivers Council’s 4,200 Project and Great Salt Lake Waterkeeper, both operational; the Skull Valley Band’s existing reservation and its associated water rights, not yet litigated but legally present; the Utah Geological Survey’s basin-flow model, which provides the quantitative foundation for any future challenge; and the political record of the 2022 and 2023 Strike Force proceedings, in which the legislature acknowledged the lake’s crisis in principle while declining to bind the data-center sector in practice.

What present organizers can borrow

Map: Cedar Valley organizing landscape and parallel atlas cases

The Cedar Valley case arrived in a national inventory of data-center displacement that had no precedent at the turn of the 2020s and had dozens of examples by 2025. Business Insider’s September 2025 interactive map of United States data-center locations documented the Mountain West as one of the fastest-growing clusters outside Northern Virginia, with Utah’s Cedar Valley among the earliest cases of documented Mormon-agricultural land assembly for hyperscale use.³ The Cedar Valley cluster is not merely a Utah story; it is a template that land-assembly intermediaries have since carried to the Snake River Plain in Idaho, to Laramie County in Wyoming, and to the High Plains around Greeley and Cheyenne. Each of those cases involves a farming community, a stressed aquifer, a vertically integrated monopoly utility, and a state economic-development incentive structure that places the infrastructure cost on the residential base and the resource cost on the water column.

The most transferable lesson from the Cedar Valley case is the water-disclosure gap. Utah’s failure to require metered, publicly reported water consumption from data-center operators allowed Eagle Mountain City to hold Meta’s 35-million-gallon draw confidential for years while the basin’s stress accumulated.² Communities in Idaho, Wyoming, and Colorado that are currently confronting hyperscale land assembly can use the Utah record to argue, in their own state legislatures and before their own public utility commissions, that disclosure requirements must precede construction approval rather than follow it. The Utah Rivers Council has articulated this argument in its legislative submissions; those documents are publicly available and available for direct adaptation.

The second transferable lesson is the Jordan River chain. Utah Rivers Council’s 4,200 Project succeeded in connecting a localized groundwater story, Cedar Valley basin stress, to a statewide ecological catastrophe, Great Salt Lake decline, that commands political attention the basin story alone would not generate. The lesson for organizers in other basins is methodological: identify the downstream public-interest anchor that connects the localized industrial draw to a widely recognized harm. In Ada County, Idaho, the Snake River’s downstream salmon runs are that anchor. In Laramie County, Wyoming, the Platte River compact with Nebraska is that anchor. The data exists in every basin; the organizing work is to make the connection legible to a legislature and a press corps that may not know the hydrology.

The Chávez Ravine essay in this atlas documents the mechanism by which a municipality structures a land transfer to a private developer behind closed planning votes and confidential agreements, producing completed facts before the affected community can organize a response. The Cedar Valley land assembly followed the same structural path: by-right zoning eliminated public hearings, confidentiality agreements eliminated public water data, and the PILOT incentive structure eliminated the tax-revenue signal that would otherwise alert the county to the scale of the industrial footprint arriving. The organizers who came later, the Utah Rivers Council, the Alliance for a Better Utah, the Sierra Club Utah Chapter, all worked to reconstruct the public record that Eagle Mountain City and Meta had designed the process to obscure. The method worked in Chávez Ravine’s eventual reckoning, and it is working in Cedar Valley: the Grist investigation, the Strike Force legislative record, and the Utah Rivers Council’s basin modeling have together produced a public account that the 2022 Legislature did not have.

The Cabrillo Village cooperative in Ventura County supplies the third lesson, though it requires translation to the Cedar Valley context. The Cabrillo farmworkers organized a cooperative purchase because they were tenants facing eviction; Cedar Valley’s agricultural sellers were landowners who chose to sell. The relevant lesson is not the cooperative purchase per se but the longer organizing principle the Cabrillo case demonstrates: that agricultural communities facing speculative land-assembly pressure benefit from legal-entity structures that allow collective negotiation rather than parcel-by-parcel individual sales. In Cedar Valley, the parcels that remain in agricultural or range use are precisely those whose owners did not sell individually to the intermediaries. Those owners now face a different kind of pressure, the transmission easement corridors that Rocky Mountain Power will need for the 400-megawatt Tract build. The Utah Rivers Council’s Waterkeeper program and the Alliance for a Better Utah’s ratepayer work both provide organizational infrastructure that remaining agricultural landowners can draw on to negotiate easement terms or to challenge the necessity findings that eminent-domain proceedings require.

The Utah Public Service Commission proceedings on Rocky Mountain Power’s large industrial tariff for data-center customers are the most immediate venue for public intervention as of April 2026.⁸ The Alliance for a Better Utah files in those proceedings and publishes its comments; residential ratepayers in the Rocky Mountain Power territory can participate through the alliance or directly through the Office of Consumer Services, the statutory ratepayer advocate before the commission. The commission’s rate-design decisions in the next two to three years will determine whether the cost of transmission infrastructure for the Eagle Mountain cluster falls primarily on the industrial customers whose load requires it or spreads across the residential base in a pattern that residential customers cannot see clearly without the kind of translation work the alliance performs.

The atlas records the Eagle Mountain cluster at the moment when the scale of the assembly is visible, the groundwater cost is partially disclosed, the downstream lake-elevation consequences are scientifically documented, and the legislative response remains unfinished. Utah Rivers Council’s Great Salt Lake Waterkeeper has the legal standing to file; it has not yet done so in a case directly naming Cedar Valley data-center withdrawals. Alliance for a Better Utah is active in the commission proceedings; it has not yet produced a comprehensive public account of what the Tract 400-megawatt build’s transmission and ratepayer costs will total. Both capacities exist; both are pointed at the right targets. The Cedar Valley agricultural landscape is largely gone. The water dispute is not.
