Kansas water use is declining, according to a new report from the U.S. Geological survey.
In 2015, Kansas used on average more than 4 billion gallons of water each day. That’s down nearly 25 percent from 1990. Of that, 2.6 billion gallons per day are used for irrigation — a decrease of 36 percent from 1990.
“What we’re doing is great, it’s just not enough of it,” Kansas Water Office Director Tracy Streeter said.
He’s particularly concerned about areas of western Kansas where farmers draw from the diminishing Ogallala aquifer.
“Overall, we’ve got to see more widespread adoption of conservation efforts,” he said.
The top three water consuming counties are Stevens, Finney and Seward — all located in southwestern Kansas.
Linn County, in eastern Kansas, withdraws the most water per day of any county. The culprit is the LaCygne coal-fired power plant, which withdraws 610 million gallons per day. But the plant puts almost all the water it withdraws back into the lake it comes from, consuming just 1 percent of it.
Mandy Stone is a hydrologist at the USGS in Kansas. She said the data is a good tool to show policymakers, and Kansans, where their water comes from and where it goes.
“This water use data is important, ultimately because all of us in the economy depend on water every day,” she said.
