DS-777 Spatial Location of Stream Elevations for the Northern High Plains Groundwater-Flow Model in Parts of Colorado, Kansas, Nebraska, South Dakota, and Wyoming

This data set is one of many developed in support of The High Plains Groundwater Availability Project and the USGS Data Series Report: 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 from the National Hydrography Dataset Plus (NHD+) 1:100,000 stream polyline data converted into points and attributed with elevation values in feet above sea level. Streams were initially included if they had a mean estimated base flow of more than 10 cubic feet per second (based on streamflow data from long-term streamflow-gaging stations operated by the USGS or the Nebraska Department of Natural Resources). The stream network then was expanded to include selected streams that were deemed hydrogeologically important but had a mean estimated base flow of less than 10 cubic feet per second.
