VICKSBURG, Miss. – The U.S. Army Corps of Engineers (USACE) Vicksburg District, in coordination with the USACE St. Paul District, is deploying the Dredge Dubuque to perform critical dredging on the Ouachita-Black River in Louisiana starting in late August. The dredge will remove shoaling in the navigation channel caused by significant high-water events on the Ouachita-Black River during 2019. This effort will allow the waterway to remain open to commercial navigation. The Ouachita-Black River is an inland navigation river system that begins at the confluence of the Red and Black rivers.
