description Atchafalaya River Delta Overview

The Atchafalaya River Delta is a dynamic coastal landform located in southern Louisiana where the Atchafalaya River meets the Gulf of Mexico. Fed by a significant distributary of the Mississippi River, it is one of the few actively prograding, or land-building, deltas along the Gulf Coast. The basin contains the largest continuous tract of bottomland hardwood swamps in the United States and supports substantial populations of waterfowl and marine life. It serves as a major focus for coastal restoration efforts aimed at mitigating wetland loss in the region.
