As the federal government forces historic cuts on Colorado River water rights, Kearny is moving to lock in its independence. Here is what is in play — and how our deep granite-vault aquifer holds the key.
Section 1 — The Crisis
The operating guidelines for the Colorado River expire in 2026. Because the seven basin states — Arizona, California, Colorado, Nevada, New Mexico, Utah, and Wyoming — cannot agree on a deal, the Bureau of Reclamation has stepped in to prevent the total collapse of Lake Mead and Lake Powell with a strict long-term management strategy.
The federal government is floating alternatives that would replace the old prior appropriation doctrine with pro-rata (equal percentage) cuts across all users — regardless of how senior their water rights are. This would upend decades of established Arizona water law and erase the seniority protection communities have held for generations.
Under nearly every federal scenario, Arizona faces the steepest reductions. Governor Hobbs has already offered to cut the state's Colorado River allocation by 27 percent. That cut hits every community dependent on surface river flow — unless they have already secured an independent underground source.
For Kearny, a defensive posture is not enough. Kearny needs an offensive water strategy — one that makes the Colorado River negotiations irrelevant to the Town's water future.
Section 2 — The Goal
In a world of tightening surface water restrictions, the absolute best-case scenario for our town looks like this:
We legally and physically isolate Kearny's water supply from the volatility of sub-river flow restrictions and surface water cutbacks. We achieve this by proving we are tapping a secure, isolated underground resource — not surface-dependent river flows. No river compact can reassign it. No federal guideline can reduce it. It belongs to Kearny under Arizona state law.
Kearny already has the foundation most Arizona municipalities would spend millions to acquire: confirmed deep granite-vault aquifer wells, camera-inspected, water present, sitting below 800 feet. The question is whether the Town files to own that water — before someone else does.
Section 3 — Why Shallow Wells Are Failing
Before understanding the solution, it is important to understand the problem at ground level. As drought intensifies and surface aquifers drop, shallow alluvial wells across the region are experiencing a dangerous phenomenon called bedrock drawdown — where the surface water table collapses and water migrates deeper into fractured bedrock formations, leaving shallow pumps running in air.
The diagram above shows precisely what is happening in Kearny's basin right now. Shallow surface-connected water is evaporating and declining. But deeper, beneath the fractured bedrock layer, a separate and protected water source is forming — fed by percolating water that has moved below the evaporation zone entirely. This is not a liability. It is an opportunity — if the Town files to own it.
Section 4 — The Legal & Geological Shield
To secure long-term water rights and shield Kearny from federal or state cutbacks, we have to look down — specifically, beneath the 800-foot mark in the Kearny Basin. Understanding why requires understanding the most powerful competing legal mandate Kearny faces: the 1935 Globe Equity Decree.
The Globe Equity Decree of 1935 is a federal court adjudication governing water rights along the Gila River system in Arizona — including alluvial groundwater directly connected to Gila River subflow. Any well drawing from shallow water hydrologically connected to subflow is operating under the Globe Decree's shadow — subject to curtailment, tribal senior claims, and federal reallocation. This is the primary competing mandate Kearny must defeat to achieve water independence. The solution: go deeper than the Decree can reach.
"Any person, the state of Arizona or a political subdivision thereof may appropriate unappropriated water for domestic, municipal, irrigation, stock watering, water power, recreation, wildlife… The person, the state of Arizona or a political subdivision thereof first appropriating the water shall have the better right."— A.R.S. § 45-151 | Arizona Revised Statutes, Title 45 (Waters)
The Town of Kearny is a political subdivision of the State of Arizona — it has full legal standing to file this appropriation right now. A prior appropriation filing establishes Kearny's seniority date. Every competing claim filed after that date is junior. Permanently. And if the Vault wells are confirmed to tap water below the Globe Decree's reach, the filing may fall outside Gila River adjudication entirely — the precise question the hydrological study is designed to settle.
Section 5 — The Long-Term Play
Securing the deep water rights allows Kearny to transition from a reactionary setup to a permanent, sustainable MARS (Managed Aquifer Recharge and Storage) framework. Instead of simply mining the aquifer, MARS allows the Town to actively manage, store, and recycle water assets underground — building a self-replenishing hydrological bank owned entirely by Kearny.
Draw exclusively from the protected granite-vault formations below 800 feet — below the Globe Decree's reach. Guarantees baseline municipal supply independent of any surface water restrictions or federal river management decisions.
Direct treated municipal effluent and seasonal stormwater runoff into dedicated, permitted containment areas rather than letting it evaporate or escape downstream. This water becomes the feedstock for the MARS recharge cycle.
Using engineered spreading basins or shallow injection fields, allow collected water to filter down through the soil profile — purifying it as it recharges the upper water table and the deep containment zone. Water banked under Kearny's name.
The recharged water forms Kearny's underground water bank. By putting water back in, the Town offsets deep pumping, stabilizes the local water table, and completely insulates itself from regional river restrictions — now and for future generations.
Section 6 — The Action Plan
Mayor Curtis Stacy is taking the right path forward. Rather than rushing, he has engaged Mackenzie and Associates, an independent hydrology firm, to professionally investigate whether Kearny's deepest wells lie beyond the Globe Decree's reach — the exact question that has to be answered before the Town can act. That measured, evidence-first approach aligns squarely with the goal Project 88 has championed from day one: verify the deep-water opportunity, then secure it. The Town and Project 88 want the same outcome — a confirmed, independent water supply Kearny can own for generations. The urgency is real: mine dewatering operations and tribal water-right adjudications are active in the region, so the verification work happening now is exactly the right first move.
Mayor Stacy files an application to appropriate the deep groundwater of the Vault wells for municipal beneficial use with ADWR. This establishes Kearny's priority date — the legal timestamp that makes the Town senior to all future filers in the deep granite-vault zone.
This step is already in motion. The Town has engaged Mackenzie and Associates to determine whether the Vault wells tap water below the 800-foot confining layer — geologically isolated from Gila River alluvial subflow. If confirmed, this is the legal firewall that could place Kearny's appropriation outside Globe Decree jurisdiction and beyond the reach of tribal senior rights. The study's findings will tell the Town where it stands.
Formally classify the entire Vault well system as exclusive municipal water infrastructure under Arizona groundwater law — shielding it from agricultural conversion, third-party industrial use, or mine dewatering claims in the same formation.
Launch deep well capture under the MARS framework to create a documented, legally defensible record of ongoing municipal beneficial use — the requirement that cements an Arizona prior appropriation and prevents abandonment challenges under A.R.S. § 45-189.
Extend the appropriation filing to cover Well 3 as it comes online. Apply for ADWR Underground Water Storage Facility designation under A.R.S. Title 45 Chapter 3.1 — converting MARS recharge activity into legally accrued water storage credits owned exclusively by the Town of Kearny.
The 1935 Globe Decree, the Colorado River compact expiration, mine dewatering activity, and tribal water adjudications are all converging on the same window: 2026. Communities that establish seniority now in the deep granite-vault zone — if the hydrology confirms it sits beyond the Globe Decree's reach — will enter the post-2026 water era as independent, water-secure towns. Kearny has the wells, the legal standing, and a Mayor who has put the right verification work in motion. The window is measured in months.
Securing Kearny's deep wells and building a permanent recharge solution requires proactive local governance and community backing. Let's build the infrastructure that ensures Kearny never runs dry.
