Abstract

The Mississippi River Alluvial Aquifer is a major source of water supply for irrigation in much of eastern Arkansas. Hydrologic maps of the potentiometric surface, water-level changes and depths to water in the aquifer, based on Spring 1983 measurements, are presented. The Mississippi River Alluvial Aquifer is comprised of Quaternary alluvial flood-plain and terrace deposits. The aquifer generally is partially-confined. Recharge to the aquifer is principally through precipitation and surface-water bodies. The potentiometric surface map indicates two cones of depression occurring in the aquifer beneath Arkansas, Poinsett, and Cross Counties as a result of heavy pumpage within these areas. A comparison of water-level data from 1982 and 1983 shows water levels in the aquifer generally decreasing in the area within the cones of depression. Water levels generally increased in the remainder of the area south and west of the White River, and along the Mississippi River. A map showing the depth to water below land surface indicates that water levels are generally shallowest near the Mississippi River and the Fall Line and deepest within the cone of depression.
