This report summarizes data and information gathering activities that supported groundwater management in the Wisconsin central sands for the period July 2016 through June 2017. The report supplements the previous works of Clancy et al. (2009) and Kraft et al. (2010, 2012a, 2012b, 2014, and 2016), which summarized important hydrologic literature on the central sands, provided documentation for groundwater flow models, and estimated pumping diversions and drawdowns from monitoring data. These previous works concluded groundwater pumping in the central sands is substantially impacting the region’s water levels and streamflows, and that the impacts are not explainable by phenomena such as an unprecedented drought. The conclusions about groundwater pumping impacts reinforced prognostic work by Weeks et al. (1965) and Weeks and Stangland (1971), and in turn were reinforced by more recent analyses (Bradbury et al. 2017).
