The Wisconsin Department of Natural Resources is launching a new study on the water supply in the state's central sands region.
The region spreads across eight counties in the state's mid-section and includes more than 300 lakes and more than 800 miles of trout streams.
Since the area has sandy soil that drains quickly, water levels depend greatly on groundwater levels and use from private, public and high-capacity wells. More than 3,070 high capacity wells operate in the region; they pumped more than 98 billion gallons in 2012.
The study will look at the environmental impact of water uses and options for protecting groundwater and surface water.
DNR officials anticipate the study will take more than a year to complete.
