Atchafalaya River / Northern Terrebonne Marshes restoration

This 500,000-acre water resources and marsh restoration project is designed to reduce ecological, economic and cultural losses in the Northern Terrebonne Marshes by increasing conveyance of river water from the Atchafalaya to the target marsh areas and modifying existing controls affecting marsh hydrology. The Northern Terrebonne Marshes have experienced significant wetland losses due to human impacts, subsidence, erosion and habitat conversion. Specific project objectives are:

  • Increase sediment and nutrient inputs into estuarine wetlands
  • Prevent land loss and habitat conversion
  • Protect socioeconomic resources
  • Restore marsh hydrology
  • Reduce salinity
  • Increase fresh water residence time
  • Sustain existing fish & wildlife habitat
