Groundwater flow models have recently been developed, and will continue to be developed, for many areas of Wisconsin. These models can serve two purposes in assessing the impacts of proposed wells. First, the models can be used to simulate proposed wells and their potential impacts on nearby water levels and surface water flows. Models allow hydrogeologists to simulate the combined influence of multiple wells over large areas. Second, models serve as databases of hydrogeologic information specific to the region that is simulated. These models are in the public domain and are available for use by consultants or DNR personnel.
Models developed by several different organizations are cataloged here, including WGNHS, the U.S. Geological Survey (USGS), and the Central Wisconsin Groundwater Center (CWGC).
Publications of the Wisconsin Geological Survey included on this application are specifically chosen to assist management of proposed well locations. The publications included are countywide to local groundwater flow modeling studies, hydrologic and hydro-geologic reports, water table maps, and county geologic bulletins and maps. This list of publications does not represent the full extent of WGNHS’s publication database. Please visit… for publications relating to statewide publications and maps, soil surveys, land use studies, and mining studies.
Geophysical logs are logs created by raising or lowering a set of probes and/or sondes in a well. Caliper, fluid conductivity, flow, fluid resistivity, gamma, digital or acoustic image, resistivity, self-potential, single point resistance, and temperature logs may be included on an individual well’s Geophysical log indicating lithologic and hydrologic properties. The probes take continuous or discrete measurements indicating specific lithology and hydrologic properties. Logs collected up to 1997 were taken using a paper logger and scales may vary. Starting in 1997 the logs were taken in a digital format with improved measurement accuracy. Please take into account all geophysical and borehole logs in partnership with general knowledge of the aquifer properties.
Detailed information about the types of borehole geophysical logs collected by WGNHS has been summarized here.
Geophysical logs are made available through this application in PDF format.
A new statewide springs inventory was completed in 2017.
