Kansas water experts are sounding an alarm decades in the making: Farmers and ranchers in the state’s western half must stop pumping more water out of a vast aquifer than nature puts back each year or risk the economic collapse of a region important to the U.S. food supply.
That warning is setting up a big and messy fight for the annual session of the Kansas Legislature set to open Monday.
The Kansas Water Authority is telling lawmakers that Kansas needs to break sharply with its decadeslong policy of slowing depletion while still allowing water levels to drop in the Ogallala Aquifer. The aquifer covers roughly 175,000 square miles (453,000 square kilometers) in the western and Great Plains states of Texas, New Mexico, Oklahoma, Kansas, Colorado, Nebraska, Wyoming and South Dakota.
Most of those states have areas where depletion is a problem, but the call in Kansas to “halt” the declines has farmers, ranchers and politically influential agriculture groups preparing to battle proposals that would give them less control over water and possibly could force them to cultivate fewer acres, buy expensive new equipment or turn on a dime to grow different crops.
Imposing the Water Authority’s policy means agribusinesses that drive the region’s economy would have to consume less water — perhaps as much as 30% less in some areas. Lawmakers also would have to decide whether local officials would keep driving conservation efforts or if the state would be in charge.
“The easy part was making the statement. That didn’t cost anybody anything,” said Clay Scott, who farms in southwestern Kansas. “We’re going to have to start paying for it, and we have to decide how that gets divvied up.”
Kansas produces more than 20% of the nation’s wheat and has about 18% of the cattle being fed in the U.S. The western third of Kansas, home to most of its portion of the Ogallala, accounts for 60% of the value of all Kansas crops and livestock. That’s possible because of the water.
The recommendation on the Ogallala from the water authority, a planning and advisory commission, is a response to data showing that since widespread pumping began around 1940, much of the Ogallala has lost at least 30% ofits available water and more than 60% in places in western Kansas. The Kansas Geological Survey had a team in western Kansas this week to measure well depths for updated figures.
“There are wells that are starting to run dry already, so this isn’t a distant problem in some areas,” said Tom Buller, executive director of the Kansas Rural Center, a nonprofit that promotes sustainable agriculture and family farming. “There isn’t a lot of time to solve the problem.”
The Water Authority’s recommendation comes as much of the western U.S. continues to suffer through a megadrought fueled by climate change. Parts of Kansas have had drought conditions for a year, and more than half the state has been in extreme drought since mid-September.
