PROJECT STATUS REPORT as of 6-Dec-2019

Mississippi River Sediment Trap DEAUTHORIZED

PROJECT LOCATION:

The sediment trap will be located in the Mississippi Rier between Venice and Head of Passes in Plaquemiens Parish, Louisiana.

PROJECT DESCRIPTION:

Since the 1930's, large areas of deltaic marshes have converted to open water throughout the Mississippi River delta. As a result, numerous shallow water sites located near the main river channel are available for marsh creation and restoration through dedicated dredging. The close proximity of shallow bays to the Misssissippi River deep draft navigation channel offers an excellent opportunity to coordinate annual channel maintenance operations with a large-scale restoration effort. The proposed sediment trap would consist of an area dredged out of the riverbed that would force sediment deposition. The sediment deposited into the trap would then be mined to create marsh. Hydrologic modeling suggests that a trap four miles long, 1,500 feet wide and 65 feet deep would optimize the deposition of sediment. Beneficial use sites for the project are located on the east and west banks of the river in West Bay and on the Delta National Wildlife Refuge and Pass a Loutre Wildlife Management Area. Initial construction of the sediment trap would create an estimated 1,440 acres of new wetlands in the western project area and 440 acres in the eastern project area.

PROJECT STATUS: (Project Status Last Updated: 25-Mar-2006 )

This complex project was approved for Phase I design activities in August 2002. A kickoff meeting was held in September 2002. The project work plan is under development pending a plan reformulation meeting with the LA Dept. of Natural Resources and Corps of Engineers design teams.

FUND STATUS:

The current project estimate is $354,791 , which includes $354,462 for construction first costs, and $329 and $0 for 20 years of monitoring and operations and maintenance, respectively.
