This site is operated in cooperation with the Illinois State Water Survey of the Prairie Research Institute, University of Illinois. Since well installation in 1984, water levels have been measured routinely by the ISWS, as part of its Water and Atmospheric Resources Monitoring Program (WARM). Water levels also have been measured by the USGS since 2012. Requests for the water-level data collected by the ISWS should be made through their Center for Groundwater Science (217-333-6800). |
