“Central Sands Lakes Study” 2021 UNDER CONSTRUCTION. When the Growers got their “forever permits” in 2017 Act 10, the sole bright spot was a study that was to include much of Central Wisconsin, 20 lakes, and dozens of stream miles. But the work of “three powerful lobbyists,” according to DNR staff, had the study limited to only three lakes (Long, Plainfield, and Pleasant). Nonetheless, the CSLS is a solid and honest scientific effort by a talented staff at DNR and scientists with national and international reputations, and might be the most ambitious groundwater research project in Wisconsin’s history. The study outcomes will likely be crucial to protecting our lakes and streams and wetlands from unlimited high capacity well pumping.
