Atchafalaya River Morganza Spillway further downstream is also used to regulate volume. In 1942 part of the flow of the Atchafalaya River was diverted through Wax Lake to the Gulf of Mexico further west. During the 2011 Mississippi River floods, the Old River complex was discharging more than into the Atchafalaya River, and the Morganza Floodway was discharging one-fourth of its capacity. If the Mississippi were allowed to flow freely, the shorter and steeper Atchafalaya would capture the main flow of the Mississippi, permitting the river to bypass its current path through the important ports of Baton Rouge and New Orleans.
