Water level and saturated thickness maps of the alluvial aquifer in eastern Arkansas, 1984

The Mississippi River Valley alluvial aquifer, is a major source of water for most of eastern Arkansas. Agriculture is largely dependent on the aquifer as approximately 3.3 billion gallon per day are withdrawn for that purpose. Much smaller withdrawals also occur for industrial, public supply, and domestic use. The purpose of the report is to illustrate, using the spring and fall potentiometric surface maps, the water levels in the alluvial aquifer under pre-pumping and post-pumping conditions, respectively, and to illustrate, using the depth-to-water and saturated thickness maps, the effect of heavy pumpage in the alluvial aquifer.
