Type File Geodatabase Feature Class
The GIS data in this dataset were subsequently derived from the accompanying map "Generalized Water-Table Elevation of Dunn County, Wisconsin". The map was produced as part of the Dunn County Groundwater Resource Investigation, a joint project of the Wisconsin Geological and Natural History Survey and the Dunn County Board. The purpose of the project was to compile and interpret hydrogeologic data that could be used by soil-and-water-resource and land-use planners. The map data are a regional interpretation of the water table, with an original presentation at a map scale of 1:100,000 and may not be sufficient for site-specific use.
This feature class (du_wt_ContourLines) provides the approximate elevation of the shallow water table for Dunn County, Wisconsin. Each contour line represents the average elevation of the water table, in feet above mean sea level; the contour interval is 20 feet. It is part of a dataset (M097-dataset01) containing GIS data for the map "Generalized Water-Table Elevation of Dunn County, Wisconsin". The dataset also includes points showing locations of insufficient data, lines showing groundwater flow direction, and an Esri ArcGIS Pro map file.
The original map was produced by a joint project of the Wisconsin Geological and Natural History Survey and the Dunn County Board. The United States Department of Agriculture-Natural Resources Conservation Service (USDA-NRCS) in Madison, Wisconsin assisted with digital capture of the original analog map data. Soren Sheridan provided data editing and review for the final dataset.

These data present an interpretation of subsurface hydrogeologic conditions. Overall, the accuracy of the interpretation varies throughout the study area, increasing with greater data density and decreasing with greater hydrogeologic complexity. The contour lines have an assigned accuracy value that encompasses both the horizontal and vertical accuracy. Please see the accompanying map for additional information about the interpretation and limitations. The digitized data were compared to the original map to ensure attribute accuracy.
The elevation values of the contour lines fall within expected ranges for the study area. Basic linear topology is present.
This dataset presents the contour lines of water table elevation captured from the original map. Please see the map for additional information about completeness and limitations of the interpretation.
This dataset was digitized from the original published map. Mylar map separates from the original map production process were scanned and georeferenced to the Wisconsin Transverse Mercator coordinate system. Map features were captured with both automated vectorization tools and manual editing. Feature attributes were assigned and symbology was configured to match the source map. Data quality checks were performed to ensure the data accurately represent the source map.
