The U.S. Army Corps of Engineers (USACE) is focusing channel maintenance efforts on the Crossings Above New Orleans as Southwest Pass has mostly been restored to authorized channel dimensions. The dustpan dredges: HURLEY, JADWIN and WALLACE McGEORGE and the hopper dredge BAYPORT are all working on the Crossings Above New Orleans. The USACE hopper dredge WHEELER continues dredging in Southwest Pass.
TRANSIT RESTRICITIONS FOR SOUTHWEST PASS (SWP):
The Bar Pilots enacted a high tide transit restriction that went into effect immediately on July 31, 2020 for all vessels with freshwater drafts of 46 feet or greater. This restriction was put in place after at least two vessels bumped bottom while transiting SWP. Specifically, all vessels with freshwater drafts of 46 feet or greater must transit 3 hours before or after the daily high tide.
DUSTPAN DREDGE(S) ON THE CROSSINGS ABOVE NEW ORLEANS:
The USACE continues dredging to restore or maintain at least the central 250 feet of the channel (authorized width is 500 feet) on the Crossings Above New Orleans as river stages continue to fall.
