DS-777 Spatial Locations of Wells with Water-Level Measurements for the First Occurrence of a Water-Level Measurement Recorded at a Well 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 U.S. Geological Survey Data Series Report: Geodatabase Compilation of Hydrogeologic, Water-Budget Component, and Remote Sensing data for the High Plains aquifer, 2011 (DS 777).

This dataset contains point vector data of 8,149 wells with 8,149 water-level measurement records located in areas overlying the northern High Plains aquifer in the United States. These data were acquired from the U.S. Geological Survey, Groundwater Resources Program, High Plains, Water-Level Monitoring Study at the following URL: http://ne.water.usgs.gov/ogw/hpwlms/data.html
