The Water Beneath The Economy

The economy of southwest Kansas begins hundreds of feet below the surface.

Long before a steer enters a feedyard, before a dairy cow enters a milking parlor, before grain reaches an elevator or ethanol plant, water is pumped from the Ogallala Aquifer. That groundwater transformed one of the driest regions in Kansas into one of the most productive agricultural economies in the United States. Today, however, the future of that water—and the economy built upon it—is at the center of one of the most consequential policy debates in modern Kansas history.

In June 2026, Southwest Kansas Groundwater Management District No. 3 (GMD3) released a draft Local Enhanced Management Area (LEMA) proposal that would establish groundwater-use reductions across much of the district beginning in 2028. The proposal is the result of legislation passed by the Kansas Legislature in 2023 requiring groundwater management districts to identify priority areas and develop plans to address declining groundwater supplies.¹

The proposal covers portions of Stanton, Morton, Stevens, Seward, Grant, Haskell, Meade, Kearny, Finney, Gray and Ford counties—some of the most agriculturally productive land in North America. Together, those counties sit atop the heart of the Ogallala Aquifer and account for roughly half of the groundwater pumped annually in Kansas.²

The numbers involved are staggering.

According to GMD3 planning documents, the district contains more than 4,500 farms and produces approximately 36 percent of all agricultural sales in Kansas. Annual crop sales are estimated at roughly $1.5 billion while livestock, poultry and animal-product sales total approximately $6.7 billion annually.³

But district-wide figures only tell part of the story.

A review of the 2022 USDA Census of Agriculture shows the eleven counties most directly affected by the proposal generated more than $7.6 billion in agricultural sales alone. Haskell County led the region with approximately $1.64 billion in agricultural sales, followed by Gray County at $1.27 billion, Finney County at $1.12 billion and Grant County at just over $1.05 billion. Together, the counties contain nearly one million irrigated acres and hundreds of thousands of cattle supported directly or indirectly by irrigated feed production.

The concentration of economic activity becomes even more apparent when examining individual counties. Finney County alone reported more than 150,000 irrigated acres. Haskell County reported more than 124,000 irrigated acres. Stevens County reported approximately 135,000 irrigated acres while Meade County exceeded 111,000 irrigated acres. Across the region, irrigation has become the foundation upon which feedyards, dairies, grain elevators, ethanol plants and local agribusinesses were built.

Every gallon pumped from the aquifer creates value multiple times.

The corn grown under center pivots becomes feed. Feed supports feedyards. Feedyards support veterinarians, nutritionists, truck drivers, equipment dealerships, fuel suppliers, grain handlers and meat processors. Irrigated silage and alfalfa support dairies that have become major economic engines across western Kansas. Local banks finance operations built around irrigated agriculture. County governments depend upon tax revenue generated by productive farmland and agricultural businesses.

The challenge facing the region is that the aquifer supporting that activity is declining.

Groundwater development accelerated throughout western Kansas during the 1950s and 1960s as irrigation technology allowed producers to transform semi-arid land into highly productive cropland. The result was extraordinary economic growth. Yet the Ogallala Aquifer replenishes very slowly, and for decades withdrawals have exceeded recharge across much of southwest Kansas. Kansas Geological Survey analyses show portions of the region have experienced groundwater declines exceeding 100 feet since irrigation development began.⁵

Supporters of the proposed LEMA argue the region can no longer ignore those realities.

According to GMD3 modeling, implementation of the proposed action plan could leave approximately 4.8 million additional acre-feet of groundwater in storage over the next 60 years when compared to continuing current trends.³

An acre-foot is enough water to cover one acre of land one foot deep. It equals approximately 325,851 gallons. In practical terms, 4.8 million acre-feet represents roughly 1.56 trillion gallons of water.

Spread across six decades, that equates to approximately 80,000 acre-feet—or more than 26 billion gallons—preserved annually.

For supporters of the proposal, those figures represent the possibility of extending the life of the aquifer for future generations. For critics, the numbers raise questions about what level of economic sacrifice may be required to achieve those gains.

The debate becomes even more complex when considering who depends upon the aquifer.

Agriculture is the most visible user of groundwater, but it is not the only one.

For many rural residents, the Ogallala Aquifer is not merely an agricultural resource. It is drinking water.

According to the Kansas Geological Survey, approximately 70 percent of Kansans depend on groundwater for drinking water, and in rural areas that percentage rises substantially.

For thousands of families scattered across western Kansas, the same aquifer supplying irrigation systems also fills kitchen faucets, showers, livestock tanks and household wells.

That reality is often overshadowed by discussions of crop yields and irrigation allocations.

A weakening irrigation well may reduce crop production. A failing domestic well threatens something more basic: the ability of a family to remain in their home.

As groundwater levels decline, some rural residents have already faced increasing pumping costs, deeper well installations and concerns regarding long-term water availability. While most domestic wells require far less water than irrigation systems, they remain dependent upon the same underground resource.

The LEMA debate therefore reaches far beyond agriculture.

It affects producers attempting to maintain profitable operations.

It affects feedyards and dairies dependent upon irrigated feed supplies.

It affects local governments whose tax bases are tied to productive agricultural land.

It affects schools, hospitals and businesses supported by agricultural activity.

And it affects rural families whose daily lives depend upon groundwater flowing from a wellhead into their homes.

There is also another consequence that few people consider.

Irrigation changes the climate.

Research throughout the Great Plains has shown that large-scale irrigation increases evapotranspiration, returning water to the atmosphere through plants and soil. Scientists have documented increases in humidity and moderation of summertime temperatures across heavily irrigated portions of the High Plains. In some areas, irrigation has become significant enough to influence local weather conditions.

The landscape, the economy and even the atmosphere of southwest Kansas have adapted to the presence of groundwater.

The central question facing the region is not whether groundwater conservation is necessary. Few observers dispute that groundwater levels have declined significantly.

The question is how conservation can be achieved without undermining the economic system that groundwater created.

For nearly seventy years, southwest Kansas has converted groundwater stored beneath the plains into crops, cattle, milk, jobs, tax revenue and economic growth.

The proposed GMD3 LEMA represents an attempt to slow that conversion and preserve more of the remaining resource for future generations.

Whether that effort succeeds may determine not only the future of the Ogallala Aquifer, but the future shape of southwest Kansas itself.

Because this story is not ultimately about water.

It is about everything water built.
