Geospatial database of ground-water altitude and depth-to-ground-water data for Utah, 1971-2000

The U.S. Geological Survey (USGS), in cooperation with the Utah Department of Environmental Quality has developed a geographic database of selected ground-water-level altitude contours and surfaces for Utah. The contour data are derived from studies published by the USGS and the State of Utah. The published contours were converted to digital format and attributes documenting information such as the water-level altitude, the year the study report was published, the year for which the contours were drawn, and a link to the on-line version of the study report were added to the data set. The contours were input to the database as a unique polyline feature class for each study area. The digital contours were passed through an inverse distance [...]
