Hydrologically, the aquifer is complex, characterized by discrete and diffuse flow components with large spatial variations in porosity and permeability. Regionally, the flow within the aquifer is to the south and southeast in the eastern and central part of the study area and to the northwest and north in the western part of the study area. Within Arkansas, the potentiometric-surface map based on October- December 1995 data indicates maximum water-level altitudes of greater than 1,300 feet in Boone, Carroll, and [...]
