Simulated groundwater declines in Central Arkansas

A groundwater-flow model of the Mississippi embayment was used to evaluate changes in water-level altitudes after the addition of wells that simulate potential future pumping from the Sparta aquifer in the Bayou Meto-Grand Prairie area of eastern Arkansas (shown within the black outline) for the 30-year period from 2007 through 2037. The animation portrays the time-lapse development of a cone of depression with a maximum water-level decline of approximately 102 feet, and a lesser cone of depression to the east. Selected wells are shown as grey vertical pipes. Water-level altitude declines range from 40 to 50 feet over most of the remainder of the Bayou Meto-Grand Prairie area.
