The ground-water resources of the White River basin in Hamilton and Tipton Counties were investigated by first collecting driller logs, ground-water levels, streamflow measurements, and pumping data. These data were used to map the aquifers and construct both two- and three-dimensional ground-water flow models, which provided estimates of the ground-water potential in terms of yield, drawdown, and streamflow depletion. Five confined sand and gravel aquifers interbedded in till a bedrock aquifer, and an unconfined outwash aquifer are the three major aquifer systems. A 39-million-gallons-per-day pumpage was simulated from the outwash aquifer by the two-dimensional model. Pumping was simulated at a rate that reduced the modeled saturated thickness of the aquifer at the wells by half. Pumping in the confined sand and gravel and bedrock aquifers was simulated by three-dimensional model. In this case, pumpage was simulated over smaller areas than in the outwash aquifer, and pumping plans assessed specific types of conditions, such as extent or thickness of a sand and gravel unit. Simulated pumpages ranged from 1.9 to 6.7 million gallons per day. The highest pumpages were closest to major discharge areas. (USGS)
