Abstract

This map shows the generalized contours of the altitude of water levels in wells completed in the Cockfield Formation in southeastern Arkansas for 1980. Most water levels used in constructing the map were made in the spring of 1980. However, in parts of the State water levels from the spring of 1980 were unavailable. Where data indicated no long-term changes in nearby water levels, measurements from as early as 1952 and as late as 1983 were used. At a few locations the altitude of the water surface in a stream was used to define the potentiometric surface. Available water level data limited the interpretation of potentiometric surface primarily to the area of occurrence of the aquifers south of the Arkansas River. Water level data from Arkansas and adjacent states used in the construction of this map are from the groundwater file of the U.S. Geological Survey 's National Water Data Storage and Retrieval System. This map was prepared as part of the Gulf Coast Regional Aquifer-System Analysis study. (Lantz-PTT)
