Geospatial dataset of hydrologic characteristics of the Big Sioux aquifer near Sioux Falls, South Dakota

The city of Sioux Falls, in southeastern South Dakota, is the largest city in South Dakota. The U.S. Geological Survey (USGS), in cooperation with the city of Sioux Falls, completed a groundwater-flow model to use for improving the understanding of groundwater-flow processes, estimating hydrogeologic properties, and analyzing groundwater and surface-water interactions for the Big Sioux aquifer in the model area. The model area includes the Big Sioux aquifer and the underlying hydrogeologic units from Dell Rapids, South Dakota, to the confluence of the Big Sioux River and the outlet of the Sioux Falls Diversion Channel in eastern Sioux Falls, South Dakota. The Big Sioux aquifer is the primary aquifer in the model area and the focus of the groundwater-flow model. The data provided in this feature were estimated from model results or from soil data from the U.S. Department of Agriculture Natural Resources Conservation Service and discretized to the same size as the cells used in the groundwater-flow model (200 feet by 200 feet).The cells in the feature match the model cells in size and location.
