GCC Report to the Legislature Scientific Understanding of the Resource

Scientists need consistent, long-term data in order to calibrate groundwater models and track the response of groundwater to stresses such as groundwater pumping, land use change, droughts and other extreme weather trends. To get this data, the Wisconsin Geological & Natural History Survey and the U.S. Geological Survey have jointly operated the Wisconsin Groundwater Level Network since 1946.

The data from this network of monitoring wells is the best statewide record of long–term groundwater data, so the number of active wells in the Wisconsin Groundwater Level Monitoring Network can be considered a proxy for scientific understanding of the resource.

In addition to the 97 permanent wells in this network, additional limited–term monitoring wells are managed and paid for by other ongoing groundwater studies across the state, greatly increasing the cost savings and value of the network. The total number of active monitoring wells currently in the network is shown below. To explore groundwater data from these wells, see Wisconsin groundwater level data [exit DNR]. A groundwater quality component could be added to this measure in the future.
