PROJECT STATUS REPORT as of 21-Nov-2024
West Pointe a la Hache Outfall Management DEAUTHORIZED
PROJECT LOCATION:
PROJECT DESCRIPTION:
Construction of the Mississippi River levees has resulted in a detrimental ecosystem change to this area. Levees have stopped annual flooding that served to nourish the surrounding marshes with sediments, nutrients and fresh water. Dredging of oilfield and pipeline canals in conjunction with construction of major navigation channels has provided avenues for salt water from the Gulf to intrude into low salinity brackish and intermediate marshes in the project area. Increased channelization in this area has resulted in the export and overall loss of organic marsh soils from the project area. These man-induced causes of wetland loss are compounded by a relatively high rate of subsidence in the area. The objective of the outfall management plan is to optimize the use of fresh water and sediment supplied by the existing siphon by managing water flow through the area. This will be accomplished by reducing channelized flow and routing the diverted flow across marshes or through shallow water areas instead of through larger channels so that suspended sediments are deposited and marshes are nourished and created.
