The Utah Geological Survey (UGS) developed the Groundwater Monitoring Data Portal to store and distribute large quantities of monitoring data acquired through the various monitoring networks that the UGS maintains. The portal allows easy access to view, query, and download groundwater monitoring data from a dataset containing more than 12 million records, including well and piezometer water-level records and spring and surface flow measurements. Individual wells or surface water monitoring locations may be selected and additional information is available to view when clicking on their respective "Site Details" button. Data may be viewed directly in the "Site Details" panel, downloaded in CSV format, or a well or spring summary report may be viewed or downloaded in PDF format. CSV files may be imported into Microsoft Excel or other software for further analysis and plotting. This application would not have been possible without the initial efforts of Kevin Thomas, Quinton Williams, Steve Bowman, Lucy Jordan, and Hugh Hurlow. Continued efforts from Paul Inkenbrandt, Lance Weaver, and Martha Jensen keep this application in working order.
