DNR Groundwater Use Shows Over 1.9-Trillion Gallons Used

Wisconsin cities, businesses, industries and agricultural operations were among the state’s largest users of water in 2017, pumping more than 1.9-trillion gallons of groundwater and surface water, according to a Department of Natural Resources report.  The state’s sixth annual water-use report tallies how many gallons were pumped by municipal water systems, agricultural operations, utilities and other sources that have the capacity to pump more than 100,000 gallons of water per day from groundwater or from lakes or rivers.  Of the total groundwater and surface water used in 2017, 77-percent was for power generation, according to the report.  Overall water use in Wisconsin was four percent higher in 2017 than in 2016 due to an increase in power generation and municipal water supply use.  Only ten percent of water use was for municipal public water.  Polk County ranks 35th out of Wisconsin’s 72 counties in groundwater withdrawals.  Wisconsin’s water use reporting requirements are part of the Great Lakes Compact, a 10-year-old agreement between the Great Lakes states and Canadian provinces to collectively manage water quantity in the Great Lakes basin.
