A representative from U.S. Army Corps of Engineers (Corps) has advised that the revetment operations at Gravolet were delayed by the extreme weather conditions over the last few days.
The work at Gravolet is now expected to be completed no later than Sunday, December 30, 2018 and will not be completed today as originally scheduled.
The Corps is conducting a site visit to the Poydras location to determine if returning to finish revetment operations there is possible.
The Carrollton Gauge at New Orleans had a reading of 12.49 feet at 1300 hours today.
The remaining work at Gravolet (ongoing) and possible return to Poydras both require significant transit restrictions that are detailed in the attached Marine Safety Information Bulletins (MSIB).
The Coast Guard, Corps, Pilots and navigation stakeholders will continue to monitor the operations and navigational safety, additional adjustments may be warranted. The transit restrictions established in the attached MSIBs may also change, the U.S. Coast Guard Vessel Traffic Service Lower Mississippi River (VTS LMR) indicates an updated MSIB should be issued when the mat sinking operations return to Poydras. The transit restrictions are expected to be the same, but minor changes could be warranted.
The calendar below is not official yet, but is an update based on the discussion with Corps representatives, updates will be issued upon confirmation from the Corps regarding revetment operations.
