Simulated effects of ground-water pumpage on stream-aquifer flow in the vicinity of federally protected species of freshwater mussels in the lower Apalachicola-Chattahoochee-Flint River basin (Subarea 4), southeastern Alabama, northwestern Florida, and southwestern Georgia

Albertson, Phillip N.; Torak, Lynn J.

Abstract:

Simulation results indicate that ground-water withdrawal in the lower Apalachicola-Chattahoochee-Flint River basin during times of drought could reduce stream-aquifer flow and cause specific stream reaches to go dry. Of the 37 reaches that were studied, 8 reaches ranked highly sensitive to pumpage, 13 reaches ranked medium, and 16 reaches ranked low. Of the eight reaches that ranked high, seven contain at least one federally protected mussel species. Small tributary streams such as Gum, Jones, Muckalee, Spring, and Cooleewahee Creeks would go dry at lower pumping rates than needed to dry up larger streams. Other streams that were ranked high may go dry depending on the amount of upstream flow entering the reach; this condition is indicated for some reaches on Spring Creek. A dry stream condition is of particular concern to water and wildlife managers because adequate streamflow is essential for mussel survival.
