The U.S. Army Corps of Engineers (USACE) is working to restore the deficient reaches of the Mississippi River Ship Channel (MRSC) in the area of Southwest Pass with two industry hopper dredges and one government hopper dredge. The industry hopper dredges BAYPORT and NEWPORT and the USACE’s hopper dredge WHEELER are working on assignments in the area of Southwest Pass. The dustpan dredges, JADWIN and WALLACE McGEORGE and the hopper dredge GLENN EDWARDS are working on the Crossings Above New Orleans and will soon be joined by the dustpan dredge HURLEY. The focus on channel maintenance is shifting upriver to the Crossings Above New Orleans as the water levels begin to rapidly recede. The National Oceanic and Atmospheric Administration’s National Weather Service’s Extended Streamflow Prediction (28-Day) for the Baton Rouge Gauge predicts a drop from 28.28 feet to 20.1 feet on July 27, 2020 – a difference of 8.18 feet.
