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 LiDAR data generalized to 30 meter grid cells; and the elevation of large and small lakes from the same generalized LiDAR data. The river and lake 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 from the generalized LiDAR data. 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.
