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 Open-File Report 99-267. Purpose: The purpose of this data set is to refine and update the extent of the High Plains aquifer based on currently available information. Supplemental_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.

Process_Step: Process_Description: Began with the boundary extent defined by OFR 99-267. As more recent digital vector data sets were located for each state, the arcs of the original boundary were deleted and replaced by the new arcs from the state data source. The first data set to be inserted in the new boundary extent was for Kansas. The data were retrieved from the Data Access and Support Center (DASC) and consisted of arcs defining the High Plains boundary within the state of Kansas. See Supplemental Information section for source citation.

The arcs were copied into this data set and replaced the old boundary in Oklahoma.

Connecting arcs were added right along state borders to "smooth" areas where the location of geologic boundaries did not match across the border. This was required along the boders of Colorado and Wyoming, Oklahoma and Texas, Oklahoma and Kansas, Oklahoma and Colorado, and New Mexico and Texas.
