Lineage

The water-table elevation was estimated from several sources of data including water levels in wells constructed in the surficial sand aquifer; the elevation of rivers and perennial streams from a hydrologically-corrected Digital Elevation Model (DEM) constructed by DNR Division of Ecological and Water Resources for mapping surface watersheds; and the elevation of large and small lakes from the same DEM. Wet soils and shallow lakes indicate that the water table is close to the land surface. Those data were supplemented with Natural Resources Conservation Service (NRCS) polygon shapefiles of soils and associated tabular data that estimate the depth to water table for wet soils. A 100-meter grid of points was established over wet soil polygons; estimates of depth to water for each point were sampled from each relevant soil polygon and surface elevations were determined by sampling the hydrologically-corrected DEM. The water-table elevation at each point was calculated by subtracting the depth to water from the surface elevation.

 

All of the above data were converted to sample points and interpolated with the ArcGIS Topo to Raster tool to create the water table elevation model.
