This data release consists of two directories: DepthToWater and WaterLevelModels. The DepthToWater directory contains five Microsoft Excel workbooks that present depth-to-groundwater data and drawdown analyses from five wells during an aquifer test at Well ER-6-1-2 Main (USGS site identification number 365901115593501). The WaterLevelModels directory contains 11 Microsoft Excel workbooks that present 10 archived SeriesSee (Halford and others, 2012) water-level models that were used to examine drawdown at 9 wells during the same aquifer test. An additional Microsoft Excel workbook (Continuous+TransformedData.xlsx) contains all raw and transformed data series used in the 10 water-level models.
