This report presents information concerning the occurrence, availability, movement, recharge, discharge, and mineral quality of the ground water in Desha and Lincoln Counties in eastern Arkansas.

It includes:

• A discussion of the topography, climate, and drainage of the study area
• A discussion of both the surface and sub-surface geology, including lithology and structural, with special reference to water-bearing units
• Structural contour maps of the Cretaceous system, of the Midway group (Paleocene), and of the Wilcox group (Eocene) in the study area
• Six geologic sections depicting formation relationships
• A discussion of the local hydrology, 7 pumping tests and their results, and recharge, movement, and discharge of ground water
• A discussion of water level fluctuation and use of ground water, with 5 hydrographs and one pumping chart
• A discussion of chemical quality of ground water in the study area, including graphic representation of selected chemical analyses of ground water, areal distribution map of chloride content, and a classification chart of ground water used for irrigation in the study area
• A table with well and spring records, including location, use, yield, owner, driller (if well)
• A table of water levels in wells in the study area
• A table of logs of test holes and wells
• A table of chemical analyses of water from wells and springs
• Four plates displaying correlation of formations by use of electric logs
