The focus at the summit hosted by Gov. Sam Brownback was how to extend the life of the aquifer, for its loss would be a major economic issue for the state. Roughly 94 percent of the groundwater is used for irrigation, which supports livestock, meatpacking, ethanol and other agricultural industries in Kansas. At the summit, the governor took aim at the state’s “use it or lose it” water requirements, which he said are outdated and need to be eliminated.
Under the law, farmers’ water rights could be considered abandoned if they don’t use their water. State officials have said that often prompts farmers to irrigate when it isn’t necessary. “Without Ogallala water, agriculture and all of its related businesses could not be sustained,” Brownback said. “Manufacturing could not continue, recreational opportunities would diminish, and the towns in the area would cease to exist.”

For years, the Kansas Geological Survey and the state’s Division of Water Resources have measured water levels in 1,400 wells in the aquifer. The rate of decline had been lessening since the 1960s, but that changed after 2000, when another drought cycle hit western Kansas and farmers began pumping more water out of the aquifer.
In southwest Kansas, where the drought has been particularly bad, well tests in January showed the water level in some parts of the aquifer had dropped more than 5 feet in a year, said Brownlie Wilson of the Kansas Geological Survey at the University of Kansas. The aquifer generally recharges only about half an inch a year.
