This data release includes a polygon shapefile of grid cells attributed with values representing the simulated base-flow, evapotranspiration, and groundwater-storage depletions as a percentage of hypothetical well pumpage for the 2011-2060 time period. Depletions were simulated by the Phase-Three Elkhorn-Loup Model (ELM), constructed using MODFLOW-NWT (Niswonger and others, 2011). Each polygon represents one model grid cell, with pumping specified from either layer one or layer two of the model. All values are estimates and approximations. The phase three ELM simulated the High Plains aquifer in north-central Nebraska from predevelopment (pre-1895) through 2060 (Flynn and Stanton, 2018). The simulation was calibrated...

This data set contains 2,611 water levels collected by Natural Resources Districts in Central Nebraska. These water levels were collected by the districts to monitor groundwater levels within the districts. The water levels were provided to the USGS for use as calibration targets to the Elkhorn and Loup River Basin - Phase Three groundwater flow model. The water levels have not been previously published. This record serves as the publication record of the water levels in support of the Elkhorn and Loup River Basin - Phase Three groundwater flow model report.
