(B1) Spatial data set of mapped water-level changes in the High Plains aquifer, 2013 to 2015

The High Plains aquifer extends from south of about 32 degrees to almost 44 degrees north latitude and from about 96 degrees 30 minutes to 106 degrees west longitude. The aquifer underlies about 175,000 square miles in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This dataset consists of a raster of water-level changes for the High Plains aquifer, 2013 to 2015. This digital dataset was created using water-level measurements from 7,529 wells measured in both 2013 and 2015. The map was reviewed for consistency with the relevant data at a scale of 1:1,000,000.
