The ground-water resources of the White River basin in and near Delaware County, Indiana, were investigated by mapping the aquifers, calculating their hydraulic properties, determining the distribution of potentiometric head in the aquifers, and determining some of the components of the ground-water budget from data collected in the field. This information was used to construct and calibrate a seven-layer digital ground-water flow model. The model was used to assess ground-water potential in terms of yield, drawdown, and depletion in streamflow. Six confined sand and gravel aquifers interbedded in the drift, an unconfined outwash aquifer, and a bedrock aquifer are the three most important aquifer systems in the study area. Model analysis of seven pumping plans provides a general assessment of the water-yielding potential of the three major aquifer systems in the study area. Results indicate that yields of as much as 3.0 million gallons per day can be developed at some locations. Model simulations also indicate that pumping will generally decrease flow in streams by no more than 10% discharging more than 2 cubic feet per second. (USGS)
