DS-777 Spatial Location of Gages with Total Flow and estimated Base Flow, for the Predevelopment Simulation Period for the Northern High Plains Groundwater-Flow Model in Parts of Colorado, Kansas, Nebraska, South Dakota, and Wyoming

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 Natural Resources Stream [...]
