Geospatial Database of Ground-Water Altitude and Depth-to-Ground-Water Data for Utah, 1971-2000

Prepared in cooperation with the
UTAH DEPARTMENT OF ENVIRONMENTAL QUALITY

By Susan G. Buto and Brent E. Jorgensen

Abstract

 A geospatial database of ground-water-level altitude and depth-to-ground-water data for Utah was developed.  Water-level contours from selected published reports were converted to digital Geographic Information System format and attributes describing the contours were added.  Water-level altitude values were input to an inverse distance weighted interpolator to create a raster of interpolated water-level altitude for each report.  The water-level altitude raster was subtracted from digital land-surface altitude data to obtain depth-to-water rasters for each study.  Comparison of the interpolated rasters to actual water-level measurements shows that the interpolated water-level altitudes are well correlated with measured water-level altitudes from the same time period.  The data can be downloaded and displayed in any Geographic Information System or can be explored by downloading a data package and map from the U.S. Geological Survey.
