Drought Assessment and Local Scale Modeling of the Sioux Center Alluvial Wellfield

PDF versionPDF version


Publication Year: 



The Iowa Geological Survey (IGS) completed a drought assessment to evaluate current and future groundwater storage and availability for the City of Sioux Center’s (City) alluvial wellfield. The City had previously hired DGR Engineering to design two low-head dams along the west fork of the Floyd River. A calibrated groundwater flow model was developed by the IGS to provide the City with a quantitative evaluation of the additional groundwater storage potential of the low-head dams. Various other drought strategies to enhance both aquifer storage and induced (river) recharge were also evaluated using the calibrated flow model.
