About the network
Crisscrossing the state is a network of wells that are routinely monitored to keep tabs on Wisconsin’s groundwater levels. Begun in 1946, the monitoring wells have generated many years of data. The information has been instrumental in helping to create a picture of how water use and pumping, land use, even climate change affect groundwater supply.
New wells, new data
The groundwater monitoring network received a boost in August 2012 when the Wisconsin Department of Natural Resources (DNR) allocated money to replace and upgrade several wells and spring monitoring sites in Milwaukee and Waukesha Counties. The DNR, the Wisconsin Geological and Natural History Survey, and the U.S. Geological Survey will install new equipment to better understand groundwater movement and quantity in the highly populated southeastern Wisconsin.
