“…Because of the deficient precipitation and soil moisture, there was a 22 percent increase in the amount of irrigation water applied to rice as opposed to that applied during normal years of precipitation and an 80 percent increase in the amount of irrigation applied to cotton and soybeans as opposed to that applied during normal years of precipitation. The increased withdrawals of ground water in 1980 for crop irrigation were reflected by the lowering of ground-water levels (Edds, 1981) between March 1980 andMarch 1981. Declines in water levels in the alluvial aquifer, the principal source of irrigation water, ranged from 0.61 to 1.83 m. Water levels in the Sparta Sand, a supplementary-source aquifer for irrigation, declined as much as 3.05 m. The water-level changes in both aquifers between 1980 and 1981 represent a decline rate of 5 to 10 times greater than the long-term average rate.…”

This report, prepared by the U.S. Geological Survey in cooperation with the Arkansas Soil and Water Conservation Commission, the U.S. Soil Conservation Service and local Conservation Districts, contains ground-water level measurements in 485 wells tapping the Mississippi River Valley alluvial aquifer of eastern Arkansas. The measurements were made by district Soil Conservation Service personnel during 1985. The purpose of this report is to provide these data to other State and Federal agencies as well as to private landowners. The shallowest pre-pumping water levels occurred in Clay, Independence, and Mississippi County where most water levels were within 20 feet of land surface. Counties where water levels of 100 feet below land surface or greater were measured included: Arkansas, Lonoke, Poinsett, and Prairie. Waterlevel measurements made during the post-pumping (recovery) season averaged 3.65 feet less than those made during the pre-pumping season. A comparison of pre-pumping water-level measurements made in 1984 to those made in 1985shows an average rise of 1.0 foot within the area (Edds and Spencer, 1985).
