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. Baseflow is the portion of streamflow derived from groundwater flow. It is an important component of the groundwater budget, and can be estimated using known total streamflow at given points through time. Daily streamflow data was collected from 25 streamflow gaging stations across the northern High Plains Groundwater Availability Study (NHPGAS) area from the National Water Information System (NWIS) and the Nebraska Department of...
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. This data set is one of many developed in support of The High Plains Groundwater Availability Project and the U.S. Geological Survey Data Series report: titled Geodatabase Compilation of Hydrogeologic, Remote Sensing, and Water-Budget-Component data for the High Plains aquifer, 2011 (DS 777). This dataset contains point vector data of locations of 16,950 wells and 90,155 well log records located in areas overlying the northern High...
The U.S. Geological Survey (USGS) refined the spatial and temporal discretization of a previously modeled area (Phase 1: https://pubs.usgs.gov/sir/2008/5143/ and Phase 2: https://pubs.usgs.gov/sir/2010/5149/) which focused on a 30,000-square-mile area of the High Plains aquifer. Regional groundwater-flow models were constructed to evaluate the effects of groundwater withdrawal on stream base flow in the Elkhorn and Loup River Basins, Nebraska. The model was calibrated to match groundwater level and base-flow data from the stream-aquifer system during the pre-1940 through 2010 period (including predevelopment [pre-1895], early development [1895–1940], and historical development [1940 through 2010] conditions) using...
A three-dimensional groundwater flow model was developed to characterize groundwater resources and the interaction of groundwater with streams and other hydrologic features in the Northern High Plains aquifer. The Northern High Plains aquifer is generally unconfined; most of the water withdrawn from the aquifer is used for irrigation. A modified version of a previously published soil-water-balance (SWB) model estimates recharge using climatic, soils, land cover data, in addition to data for groundwater withdrawals for irrigation. The SWB output was adjusted in areas where surface water is used for irrigation. The groundwater flow model results were calibrated using parameter estimation to measured groundwater levels...
