Mermentau Basin Hydrologic Restoration
Mermentau Basin Hydrologic Restoration
The Mermentau Basin Hydrologic Restoration project will address persistent marsh flooding and lack of drainage in the southern Mermentau and Cameron-Creole watersheds. The project will utilize gravity drainage to direct water southward across Highway 82 into tidally connected canals within the Rockefeller National Wildlife Refuge, as well as a series of other hydrologic features. Along with other projects in the region, the Mermentau Basin Hydrologic Restoration project will relieve pressure on the Mermentau River, allowing for more efficient drainage through …
Three Mile Pass Marsh Creation and Hydrologic Restoration
Proposed to help protect oyster and shrimp habitat, the Three Mile Pass Marsh Creation and Hydrologic Restoration Project will build a marsh buffer against potential freshwater intrusion. The project footprint will be approximately 11,000 acres, including a 660-acre area dedicated to creating new wetland habitat and restoring imperiled marsh in Malheureaux Point and Grand Pass. Existing conditions in the Biloxi Marsh make this area prime habitat for oysters and shrimp. However, if the Bonnet Carre Spillway opens to prevent Mississippi …
Houma Navigation Canal Lock Hydrologic Restoration
This project will construct a lock on the Houma Navigation Canal located in western Terrebonne Bay. The Houma Navigation Canal is a significant conduit for salt water into Terrebonne’s rapidly disappearing marshes. Construction of this project will help control salinities in the navigation canal and increase the effectiveness of the Increase Atchafalaya Flow into Terrebonne Marshes project by retaining and enhancing the distribution of fresh water in the wetlands to the north of the lock. The construction of the Houma …
Calcasieu-Sabine Large-Scale Marsh and Hydrologic Restoration Project
The Chenier Plain, located in Southwest Louisiana, is part of the Calcasieu-Sabine Basin and home to the Calcasieu Ship Channel. While the Calcasieu Ship Channel is a critical asset for navigation for the entire region, it also poses one of its greatest threats—allowing increasing amounts of salt water into nearby ecologically important freshwater marshes. This project’s purpose is to produce large-scale marsh drainage improvements that reduce the flood stress currently driving marsh vulnerability in the region. This will be done …
