Publication Year: 



The Iowa Geological Survey completed a hydrogeologic evaluation of the water resources in the Ocheyedan River aquifer in Osceola, O’Brien, Clay and Dickinson counties in Iowa. The work was funded under the Water Plan Program of the Iowa Department of Natural Resources. The primary objective of this study was to evaluate the aquifer for future water supply development. Future work will include a calibrated groundwater flow model of the Osceola County Rural Water District (OCRWD) northern wellfield, which will be used to predict future well interference, available drawdown, optimal maximum pumping rates, and quantifying induced (river) recharge.
