Lineage

Water-table information were combined to produce a water-table digital elevation model (DEM) with ANUDEM software (Hutchinson, 1997). The values of the water-table DEM, which is available as a raster DEM, were subtracted from a land surface elevation DEM to produce the water table depth model. The inputs for the water-table DEM included County Well Index (CWI) water-level data from Quaternary water-table wells (QWTA); shallow (less than 100 feet deep) bedrock water levels; shallow borehole measurements by the Minnesota Geological Survey; and elevation values of surface-water bodies, wetlands listed in the National Wetland Inventory (NWI), perennial streams, and seeps. In addition, water-table elevations were estimated from soil classifications (Poch, 1976) where redoxomorphic (partially oxidized) soils were observed indicating seasonal high water-table conditions. Intermittent streams in valleys with no shallow water-table indicators (wetlands, high water-table soils, and seeps) were assigned an assumed water-table elevation value of 10 feet below land surface. The ANUDEM algorithm uses a combination of least squares and linear interpolation.
