Lower Mississippi River (LMR) Dredging Update 21916

The Corps’ Mississippi Valley New Orleans (MVN) is presently responding to the channel in the deficient areas of Southwest Pass with a total of 4 hopper dredges and 1 cutterhead dredge.  The MVN’s hopper dredge WHEELER is scheduled to arrive SWP next week as is the industry cutterhead dredge E.W. ELLEFSEN.  The full recovery of the channel in SWP will be a longterm effort and will most likely take more than a month.  The dredges working in Southwest Pass are working to restore the central 400 feet of the channel where the fully authorized widths are either 600 feet (jetty end) or 750 feet above the jetty reach.   

The extra water on the Crossings will mask the shoaling until the Baton Rouge gauge approaches 20 feet and falling (approximation).  The MVN has now begun advanced maintenance on the Crossings with the dustpan dredge WALLACE McGEORGE dredging to restore the central 250 feet at Belmont Crossing (Mile 154 Above Head of Passes).
