  • A 1:150,000-scale template showing the study area boundary, county boundaries, and 1:24,000-scale quad boundaries was printed on mylar.
  • Randy Bradt drew interpolated water-table elevation contours on this template. Delineation of the water table relied on information available in the County Well Index (CWI) data base maintained by the Minnesota Geological Survey (MGS), including depth to water measurements taken when the wells were drilled. Since only 6 percent of the wells listed in the data base for this study area are screened in a water-table aquifer, additional information was used. Water-table elevations were inferred where the water table is expressed at some lakes, streams, and wetlands. The water elevations for these features were obtained from U.S. Geological Survey (USGS) 1:24-000-scale topographic maps. Depth to water table was also determined using seismic refraction, which measures differences in the physical properties of saturated and unsaturated geologic materials to locate the water-table surface. Results obtained from eight locations show areas with low-relief topography generally have a shallow (less than 20 feet below land surface) water table, while high-relief areas have deeper water tables, sometimes more than 50 feet below land surface. In most of the study area, the water table approximates a subdued surface topography. Contours of surface elevations generated from the USGS 1:24,000-scale Digital Elevation Model (DEM) were used to guide placement of water-table contours.
  • The contour lines were digitized in ARCEDIT
