Project Description

The Terrebonne Basin supports about 155,000 acres of swamp and almost 574,000 acres of marsh, grading from fresh marsh inland to brackish and saline marsh near the bays and the Gulf of Mexico.  The Bayou Terrebonne Increment is part of a large-scale restoration strategy for the Terrebonne Basin that would rebuild ridge and intertidal marsh habitat that has degraded due, in part, to the Deepwater Horizon (DWH) oil spill.  Overall, the entire strategy would restore approximately 5,000 acres of marsh and ridge habitat and would be implemented in four increments through multiple design and construction phases.  The increments include three ridge restoration and marsh creation projects north of Terrebonne Bay, including the Bayou Dularge Ridge, the Bayou Terrebonne Ridge, and the Point au Chien Ridge, as well as, a large-scale marsh creation component to be located in southern Lafourche Parish, just west of Bayou Lafourche and Port Fourchon. The Bayou Terrebonne Increment is a ridge restoration and marsh creation project located in western Terrebonne Parish. The ridge restoration feature of this project will restore 80 acres of earthen ridge. The marsh creation feature of this project will dredge sediment from the bay to create 1,430 acres of marsh.
