Atchafalaya

• Brief History Card: Until the 1830s the Atchafalaya River was a trickle flowing out of the Mississippi cutting a shorter, steeper route across Louisiana to the Gulf of Mexico. In 1839, the state cleared the Atchafalaya of an ancient logjam, allowing the Mississippi to scour a deeper, wider channel in the streambed. This action resulted in the former stream developing the tendency to capture the Mississippi and send it rushing through the shorter channel to the sea.The U.S. Army Corps of Engineers developed and implemented a plan to control the amount of flow from the Mississippi into the Atchafalaya.
