The deep-basin well data are summarized in an Excel spreadsheet that contains general location, source, and depth information. Individual logs are available as Adobe PDF format scans of delimited text files or graphic logs. The data were plotted from coordinates or figures in referenced reports, and in many cases locations are not precise and are limited by original map scales. Most of the water-well locations were supplied by the Utah Division of Water Rights (UDWR) as a GIS shapefile. The locations are not precise and have not been verified. In many cases, location coordinates may represent a general site locality rather than individual test locations.
