Central Sands Lakes Study

Under 2017 Wisconsin Act 10, the DNR is evaluating and modeling the potential impacts of groundwater withdrawals on three lakes in Waushara County – Long Lake and Plainfield Lake near Plainfield, and Pleasant Lake near Coloma. The Central Sands region is a contiguous area east of the Wisconsin River with sand and gravel deposits greater than 50 feet deep which spans several counties and includes more than 800 miles of trout streams and 300 lakes. Water withdrawn from this aquifer, primarily through high capacity wells, provides water for local municipalities, private water supply, industries and agriculture.
