UPDATE #1: USACE Vicksburg District extends Steele Bayou Control Structure closure

U.S. Army Corps of Engineers, Vicksburg District
Published March 11, 2022

VICKSBURG, Miss. – The U.S. Army Corps of Engineers (USACE) Vicksburg District will extend the closure of Steele Bayou Control Structure in Vicksburg, Mississippi, for approximately two more weeks.

Rising stages on the Mississippi River have created conditions that require the Steele Bayou Control Structure’s gates to be closed. The structure, which was built in 1969, combined with the Mississippi River and Yazoo Backwater levees, prevents the Yazoo and Mississippi rivers from backing up and further flooding the Delta.

The district initially closed the structure March 4  to prevent the Yazoo River from backing into the Yazoo Backwater Area. previous reports forecasted the Yazoo Backwater to crest between 87.5 and 88 feet on March 12, and the Mississippi River to crest at 40.3 feet on March 10. An increase in forecasted rainfall has shifted the crest of the Yazoo Backwater Area and the Mississippi River at Vicksburg. 

The National Weather Service (NWS) has now forecasted an inch of rainfall over the Lower Mississippi River Valley over the next seven days. The interior stage of the Yazoo Backwater Area is forecasted to crest around 89 feet, and the Mississippi River is expected to crest at Vicksburg, Mississippi, at 42 feet on March 16. The gates of the structure are expected to remain closed for the next 10 to 14 days, depending on the future rainfall.

District personnel and their local partners will continue to monitor the conditions of flood control works, including levees, flood walls and pumping stations across the entirety of the district’s jurisdiction.

The public is encouraged to contact local authorities and management officials for updates about conditions in their area and should avoid activities on or near flood control works.

The Vicksburg District is engineering solutions to the nation’s toughest challenges. The district encompasses a 68,000-square-mile area across portions of Mississippi, Arkansas and Louisiana that holds nine major river basins and incorporates approximately 460 miles of mainline Mississippi River levees. The district is engaged in hundreds of projects and employs approximately 1,100 personnel.
