The Memphis District’s W.G. Huxtable Pumping Station, located near Marianna, Ark., is one of the largest stormwater pumping plants in the world. Completed in 1977, the station performs a two-fold mission. First, it prevents backwater from the Mississippi River from entering the lower St. Francis Basin when the Mississippi River is a bank full stage. This is accomplished by four 27’ x 28’ gravity flow gates, thereby becoming a dam. Second, its 10 enormous pumps remove excess surface water impounded by the Mississippi River and St. Francis Basin levees in the most efficient manner possible. The watershed served by the plant is more than 2,000 square miles, equal to the size of the state of Delaware.
