DIGITAL MAP OF THE AQUIFER BOUNDARY FOR THE HIGH PLAINS AQUIFER IN PARTS OF COLORADO, KANSAS, NEBRASKA, NEW MEXICO, OKLAHOMA, SOUTH DAKOTA, TEXAS, AND WYOMING By Sharon Qi 2010 U.S. Geological Survey Data Series 543 This report supercedes U.S. Geological Survey Open_File Report 99-267 I. ABSTRACT This digital data set represents the extent of the High Plains aquifer in the central United States. The extent of the High Plains aquifer covers 174,000 square miles in eight states; Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This data set represents a compilation of information from digital and paper sources and personal communication. This boundary is an update to the boundary published in U.S. Geological Survey Professional Paper 1400-B and this report supersedes Open-File Report 99-267. The purpose of this data set is to refine and update the extent of the High Plains aquifer based on currently vailable information. This data set represents a compilation of arcs from a variety of sources and scales that represent the 174,000 square-mile extent of the High Plains aquifer within eight states: Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. Where updated information was not available, the original boundary extent defined by OFR 99-267 was retained. The citations for the sources in each State are listed below. The boundary also contains internal polygons, or "islands", that represent the areas within the aquifer boundary where the aquifer is not present due to erosion or non-deposition. Colorado: The arcs used to define the boundary were modified from: Green, G.N., 1992, The digital geologic map of Colorado in ARC/INFO format: U.S. Geological survey Open-File Report 92-507-D-O.
