This USGS data release represents tabular data and water-level modeling files for the 16 Pahute Mesa multiple-well aquifer tests conducted from 2009–2014. This dataset represents water-level models used to estimate observation-well drawdown during the 16 multiple-well aquifer tests. Water-level models are organized by aquifer test in zipped files. Water-level models are created using an Excel Add-in called SeriesSEE (Halford and others, 2012). The SeriesSEE Excel Add-in also is inlcuded so that water-level models can be reactivated. Once the SeriesSEE Add-In is loaded into Excel, water-level model files can be activated by opening the file, scrolling to the SeriesSEE toolbar menu, and selecting the "WLM" utility. See Halford and others (2012) for more information about SeriesSEE.
