      The Morganza Spillway in conjunction with the Old River Control Complex will transfer 50 to 54 percent of the Mississippi River floodwater flow into the Atchafalaya River and Basin. The opening of the Morganza Spillway is to lower the Mississippi River stage downstream in the Baton Rouge and New Orleans areas and reduce pressure on the levee. The nondescript lowlands surrounding the Old River Control Structure – the complex of levees, dams, floodgates, and spillways designed to prevent the great Mississippi River from changing course into the Atchafalaya – belie a fascinating history of man subjugating nature and nature’s inevitable payback.. Centuries ago, the Mississippi meandered westward at Turnbull Bend to capture the.

    Eighty-year-old Fred Kemp of Butte la Rose says of the Atchafalaya River now, "It's no good, with all that pollution; there's so much acid from the Ohio River that the water could never freeze. "There are not as many trees now; there was lots of hardwood timber and you walked where you pleased. The floods of '27 and '45 silted and killed the trees.   Sediment deposition and storage are important functions of forested bottomlands, yet documentation and interpretation of sedimentation processes in these systems remain incomplete. Our study was located in the central Atchafalaya Basin, Louisiana, a distributary of the Mississippi River and contains the largest contiguously forested riparian wetland in North America, which suffers from high Cited by:

      A total of 50 to 54% percent of the Mississippi River flow will be diverted into the Atchafalaya River and Basin via the Old River Control Complex and the Morganza Spillway. As a result 10% of the state of Louisiana could be flooded. Within the Atchafalaya Basin 2, people and 2, structures will be impacted. The Atchafalaya Basin comprises an area of , acres of swamps, lakes and water prairies. Cutting a mile-wide path across South Louisiana, it is the largest and last great river-basin swamp. But to fully comprehend and appreciate the magnificence of the Atchafalaya, you must journey back to when the Atchafalaya was as nomadic as its people.

The Atchafalaya Basin, or Atchafalaya Swamp (/ ə ˌ tʃ æ f ə ˈ l aɪ ə /; Louisiana French: L'Atchafalaya, [latʃafalaˈja]), is the largest wetland and swamp in the United d in south central Louisiana, it is a combination of wetlands and river delta area where the Atchafalaya River and the Gulf of Mexico converge.

The river stretches from near Simmesport in the north. But the Atchafalaya River Basin contains a wide range of habitats and one of the highest levels of biodiversity on the North American continent. Piazza has compiled and synthesized the body of scientific knowledge for the Atchafalaya River Basin, documenting the ecological state of the basin and providing a baseline of by: The Old River Control Structure is a floodgate system in a branch of the Mississippi River in central regulates the flow of water from the Mississippi into the Atchafalaya River, thereby preventing the Mississippi River from changing ted inthe complex was built by the U.S.

Army Corps of Engineers in a side channel of the Mississippi known as "Old River. The Atchafalaya, via the Old River, threatens to capture the major flow of the Mississippi; since the midth century, however, a navigable system of dams, locks, and levees has kept the waters in ly, 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.

Greg Guirard was born in near St. Martinville, Louisiana, and moved to the West Atchafalaya Basin Protection Levee at age two. He began taking pictures in the Basin in the early 's as a teenager accompanying older members of his family on hunting and fishing trips.5/5(2).

At the "old river lock and dam" or as we locals call it, "three rivers", the Mississippi the Red and the Atchafalaya rivers all meet and where the the Red ends and the Atchafalaya starts.

Where the Atchafalaya now is where the Mississippi used to flow a couple million years ago and has since changed its course to flow east towards Baton Rouge. CONCERNED CITIZENS, FISHERMEN, AND THE BASINKEEPER FIGHT TO KEEP ACRES OF CYPRESS-TUPELO ON STATE WATER BOTTOMS FROM BEING CLEAR CUT FOR A FRACTION OF IT'S WORTH.

THANKS TO THE FISHERMEN. Louisiana’s Atchafalaya River Basin is one of the most dynamic and critical environments in the country. It sustains the nation’s last cypress-tupelo wetland and provides a habitat for many species of animals.

Endowed with natural gas and oil fields, the basin also supports a large commercial fisheries industry. Perhaps most crucial, it remains a primary component of the plan to control.

The Atchafalaya Basin Map is a full color, large scale map of the basin above Morgan City created by the LSU Louisiana Geological Survey. This very useful map was printed in and is still accurate 12 years later, even as some channels are closing up due to sedimentation.

s, the Atchafalaya River began receiving more flow through this juncture, and by the mids, an avulsion was likely so the Old River Control Project was authorized to prevent diversion of the Mississippi River to the Atchafalaya.

This paper examines the historical changes of. In this case, half of the Atchafalaya's flow below Old River is from the Red River, meaning less of the Mississippi's upriver flow can be diverted to the Atchafalaya, Jones said.

The natural levees of the Mississippi River (on the east) and the levees along its previous course (now Bayou Teche) on the west define the Atchafalaya Basin. [8] The central basin is further bordered by man-made levees designed to contain and funnel floodwaters released from the Mississippi at the Old River Control Structure and the Morganza Spillway south toward Morgan City and eventually to.

The Atchafalaya is the most original basins because it has a growing system with very stable wetlands. It is also the biggest river swamp in North America but has lost about 3, acres between and The Atchafalaya River in south-central Louisiana is of geomorphic interest because of the large volumes of flow and sediment transported and its role as a major floodway for the lower Mississippi.
