PROJECT STATUS REPORT as of 18-Jul-2025
Delta Wide Crevasses
PROJECT LOCATION:
The project is located in the Mississippi River Modern Delta and contains portions of the Delta National Wildlife Refuge, the Pass a Loutre Wildlife Management Area, and Grand Pass.
PROJECT DESCRIPTION:
Since 1927, extensive rock-armored levees constructed along the Mississippi River have prevented most of the regular flooding and over-banking events that historically created crevasses. Many natural and human-made "crevasses" or splays have silted in over time. The objective of this project is to promote the formation of emergent freshwater and intermediate marsh in place of the shallow, open water areas by either cleaning existing splays or creating new ones. Artificial crevasse construction and maintenance is an attempt to mimic the natural crevasse formation process that was responsible for buildling more than 80% of the active Mississippi River Delta.
PROJECT STATUS: (Project Status Last Updated: 23-Jun-2023 )
Construction of Phase 4 was completed on November 2021 at a cost of $594,723.07. The MR-09 project received approval for a 20 year life extension to build 20 more crevasses for $13,507,350.
FUND STATUS:
The current project estimate is $8,646,776 , which includes $745,060 for construction first costs, and $538,744 and $7,362,972 for 20 years of monitoring and operations and maintenance, respectively.
