Mid-Barataria Sediment Diversion
Mid-Barataria Sediment Diversion
Louisiana’s Barataria Basin has experienced some of the highest rates of land loss in the country. Between 1932 to 2016, the region lost nearly 295,000 acres of land. The Mid-Barataria Sediment Diversion has been a cornerstone restoration project in the state’s Coastal Master Plan and work to address this excessive land loss. The diversion is being designed to strategically mimic the natural riverine processes that built the Mississippi River Delta and to help build and maintain land in the degraded …
Large Scale Barataria Marsh Creation
This marsh creation project is in the Barataria Basin within a ribbon of wetlands stretching from the Mississippi River levee to the community of Lafitte known as the Barataria Landbridge. Historically, only a limited hydrological connection existed between the fresher upper basin and the saltier lower basin. Canals, erosion and subsidence have led to significant land loss in this area, exposing freshwater wetlands to saltwater intrusion and increased wave energy. This project will create marsh within a footprint of approximately …
Bayou L’Ours Ridge Restoration
Bayou L’Ours is one of several remnant natural ridges in the upper Barataria Basin. The goal of the Bayou L’Ours Ridge Restoration project is to revitalize this approximately 54,000-foot ridge along the bayou. This restoration project is designed to serve a multifaceted purpose, including the creation of vital coastal upland habitat, the restoration of natural hydrology and the establishment of a robust defense mechanism against waves and storm surge. By breathing new life into this historical ridge, the project seeks …
East Bayou Lafourche Marsh Creation
The East Bayou Lafourche Marsh Creation project is a Barataria Basin project in the 2023 Coastal Master Plan that will establish more than 33,000 acres of wetland habitat on the eastern side of Bayou Lafourche, along the scenic Caminada Headland. This project will serve multiple essential purposes, including the development of fresh wetland ecosystems, the rehabilitation of deteriorated marshlands and the mitigation of wave erosion. This project will help to replenish the devastated region still recovering from the impact of …
Ama Diversion
As proposed in the 2017 Coastal Master Plan, located in St. Charles Parish, the Ama Sediment Diversion will divert sediment, nutrients and freshwater from the Mississippi River to existing wetlands in the upper Barataria Basin and will also likely benefit marsh creation projects further down in the basin. With a maximum capacity of 50,000 cubic feet of water per second, the project will build and sustain wetland forests, fresh and intermediate marshes by increasing sediment input, water flow and nutrients …
Barataria Pass to Sandy Point Restoration
This barrier island restoration project is located on the southeast side of Barataria Bay and stretches from Barataria Pass to Sandy Point. Increasing tidal forces caused by ever-growing interior bays, canals, navigation channels, subsidence, wave action and sea level rise have all attributed to the erosion and retreat of these barrier islands. This has resulted in loss of barrier island habitat, exposed interior bay marshes to increases in salinity and wave action and increased the vulnerability of the entire interior …
