The U.S. Army Corps of Engineers (USACE) is working to restore authorized channel dimensions on the Mississippi River Ship Channel (MRSC) in the area of Southwest Pass with the industry hopper dredge BAYPORT. The dustpan dredges, HURLEY, JADWIN and WALLACE McGEORGE and the hopper dredge GLENN EDWARDS are working on the Crossings Above New Orleans. The focus on channel maintenance has shifted upriver to the Crossings Above New Orleans as Southwest Pass has mostly been restored. The long-term river stage levels are projected to recede after an ongoing rise. The National Oceanic and Atmospheric Administration’s National Weather Service’s Extended Streamflow Prediction (28-Day) issued today for the Baton Rouge Gauge predicts a drop from 23.87 feet to 18.08 feet on August 4, 2020 – a difference of 5.79 feet.
