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 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 Southwest Pass. 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 is shifting upriver to the Crossings Above New Orleans as the river stage levels begin to rapidly recede. 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 26.32 feet to 18.07 feet on July 29, 2020 – a difference of 8.25 feet.
TRANSIT RESTRICTIONS IN THE AREA OF SOUTHWEST PASS:
