Future Water Levels of Crucial Agricultural Aquifer Forecast

Aug. 26, 2013 — If current irrigation trends continue, 69 percent of the groundwater stored in the High Plains Aquifer of Kansas will be depleted in 50 years. But immediately reducing water use could extend the aquifer’s lifetime and increase net agricultural production through the year 2110.

Those findings are part of a recently published study by David Steward, professor of civil engineering, and colleagues at Kansas State University. The study investigates the future availability of groundwater in the High Plains Aquifer — also called the Ogallala Aquifer — and how reducing use would affect cattle and crops. The aquifer supplies 30 percent of the nation’s irrigated groundwater and serves as the most agriculturally important irrigation in Kansas.
