Yazoo Backwater Area Reformulation Study

The U.S. Army Corps of Engineers, Vicksburg District (Vicksburg District), is reformulating the remaining unconstructed features of the Yazoo Backwater Project Area in the Yazoo Basin, Mississippi. An array of nonstructural, structural, and combination alternatives emphasizing increased urban flood protection, reduced agricultural intensification, and fewer adverse environmental impacts has been evaluated. This report presents the results of studies that evaluate the feasibility of alternatives to address the flooding problems and meet the environmental and economic objectives of the area.
