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: 29-Aug-2011 )

High River stages delayed Project O&M annual inspections until July 19. All crevasses were in good shape. Project design team are in discussions with both USFWS and LDWF to identify the new, and final list of crevasse splays for construction (Phase 3 of 3). It is anticipated that the work could be underway by the end of 2012.

FUND STATUS:

The current project estimate is $4,728,319 , which includes $745,060 for construction first costs, and $529,552 and $3,453,707 for 20 years of monitoring and operations and maintenance, respectively.
