The primary goal of this project is to increase the flow of freshwater from the Atchafalaya River down Grand Bayou Canal via the Gulf Intracoastal Waterway (GIWW). This reintroduction of fresh river water will lower salinities and add nutrients to the wetlands south of the GIWW along the east and west banks of Grand Bayou Canal. The project is intended to increase the flow of freshwater from the GIWW into Grand Bayou Canal from approximately 600 cubic feet per second to 1,600 cubic feet per second; redirect much of the freshwater from Grand Bayou Canal into the marshes east and west of Grand Bayou Canal; create 112 acres of fresh marsh; and nourish an additional 14 acres of intermediate marsh west of Grand Bayou Canal near Highway 24. The objective of this project is to analyze existing information and determine data gaps. This will include reviewing data needed to begin initial permitting activities and developing a preliminary project design.
