These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. In 2006, a cooperative study was established to compile reliable data describing groundwater and surface-water interactions in the Elkhorn and Loup River Basins. The purpose of the study was to address state legislation that requires a sustainable balance between long term water supplies and uses of surface water and groundwater. A groundwater-flow model [hereinafter referred to as the Elkhorn-Loup Model (ELM)] was constructed as...

Several pre-existing datasets that characterize portions of the Northern High Plains aquifer base were merged together in order to define the entire base of the Northern High Plains aquifer. This digital dataset consists of the aquifer base elevation contours (100-foot contour interval) for the northern portion of the High Plains aquifer in the central United States. The boundaries were chosen to simplify boundary conditions for a computer simulation model being used for a hydrologic study of the Northern High Plains.
