Groundwater levels for each climate district are obtained from a series of monitoring wells that provide near real-time values measured as depth below land surface. These wells have been centrally located within each climate district and drilled to a specific depth to provide a representative water table status for that district. Most of these wells are located in unconsolidated glacial materials and do not represent the uppermost aquifer in the area. Mean daily water levels are shown here, however near real-time values can be obtained by clicking on the individual monitoring well sites.
