Atchafalaya River

Atchafalaya River
River, southern Louisiana, U.S. Rising in central Louisiana, it flows south 225 mi (362 km) into Atchafalaya Bay.

It is an additional outlet for the Red and Mississippi rivers during periods of high water. Its name is Choctaw for "long river."

 distributary of the Red (Red River) and Mississippi (Mississippi River) rivers in Louisiana, U.S. It branches southwest from the Red River near a point in east-central Louisiana where the Old River (about 7 miles [11 km] long) links the Red River with the Mississippi (Mississippi River), and it flows generally south for about 140 miles (225 km) to Atchafalaya Bay, an inlet of the Gulf of Mexico in southern Louisiana. Its length including the Red River is 1,420 miles (2,290 km), and its drainage area is 95,100 square miles (246,300 square km).

 The Atchafalaya, via the Old River, threatens to capture the major flow of the Mississippi; since the mid-20th century, however, a navigable system of dams, locks, and levees has kept the waters in check. Normally, some 25 percent of the Mississippi's flow is diverted into the Atchafalaya and the West Atchafalaya Floodway (an area of the basin west of, and parallel to, the river) through the Old River Control Structures at the Mississippi, but during floods such as those of 1973 and 1993, the Morganza Floodway (an area east of, and parallel to, the Atchafalaya) is utilized as well.

      Below Grand Lake (Six Mile Lake), at Morgan City, the river intersects the Gulf Intracoastal Waterway. Atchafalaya is from a Choctaw Indian term meaning “long river.”
