Lake Chapeau Sediment Input and Hydrologic Restoration

PROJECT LOCATION:

The project area incorporates the western central portion of Point au Fer Island, located in the extreme southwestern corner of Terrebonne Parish, and a portion of southeastern Atchafalaya Bay.

PROJECT DESCRIPTION:

Generally, the rate of wetland loss on Point au Fer Island is decreasing due to sediment and freshwater input from Atchafalaya Bay; however, these processes are being defeated in the Lake Chapeau area by the presence of tidal circulation between Four League Bay and the southeastern portion of Atchafalaya Bay. Major marsh loss has occurred in the area surrounding Lake Chapeau and continues to occur at a rate of nearly 15 acres per year. The continuation of these processes will result in the disappearance of the vital land bridge in the Chapeau area. The objectives of the project are to restore the marshes west of Lake Chapeau, reestablishing the hydrologic separation of the Locust Bayou and Alligator Bayou watersheds, and to reestablish the natural drainage patterns within the Lake Chapeau area.

PROJECT STATUS: (Project Status Last Updated: 29-Aug-2011 )
