Big Island Mining
State Project Number: AT-03
Project Priority List (PPL): 02
Federal Sponsor: National Marine Fisheries Service (NMFS)
Project Types: Sediment Diversion, Beneficial Use of Dredged Material, Marsh Creation
Construction Completion Date: 1998
Description:
The project includes creating a new western delta lobe behind Big Island to enhance the accretion of land beyond the west bank of the Atchafalaya River. Construction included dredging of a main stem and five branch channels designed to mimic natural channel bifurcations. Dredged material was strategically placed at elevations mimicking natural delta lobes. Re-opening the channels is allowing continued natural sediment transport and marsh growth.
