PROJECT STATUS REPORT as of 19-Apr-2024
Big Island Mining COMPLETE
PROJECT LOCATION:
The project is located west of the lower Atchafalaya River navigation channel and approximately 19 miles southwest of Morgan City, Louisiana, in St. Mary Parish.
PROJECT DESCRIPTION:
The project consisted of creating a new western delta lobe behind Big Island to enhance the accretion of land beyond the west bank of the Atchafalaya River. Construction called for the dredging of a main stem and five branch channels designed to mimic natural channel bifurcations. Dredged sediment was strategically placed at elevations mimicking natural delta lobes. Total channel length was 20,600 feet requiring the dredging of 2,470,427 cubic yards of material. Approximately 922 acres were created. Re-opening the channels is allowing continued natural sediment transport and marsh growth.
PROJECT STATUS: (Project Status Last Updated: 01-Jan-1990 )
Project cost increase was approved by the Task Force at the January 16, 1998 meeting. Construction project complete. First costs accounting underway.
FUND STATUS:
The current project estimate is $6,890,329 , which includes $6,387,336 for construction first costs, and $319,515 and $183,478 for 20 years of monitoring and operations and maintenance, respectively.
