Morganza, Louisiana 1864 of Federal troops in Morganza under General Nathaniel P. Banks, recently defeated in the Battle of Mansfield in DeSoto Parish and abandoning the Red River Campaign. According to Winters, Located at the lower end of a sharp bend of the Mississippi River, Morganza has been subjected to flooding by the great river a number of times. Levee breaches or "crevasses" occurred at Morganza and Grand Levee just downriver in 1850, 1865, 1867, and 1890. The Morganza Spillway, a major flood diversion project of the U.S. Army Corps of Engineers, is located immediately north of the town. Construction on this
Mississippi River Basin Model 1937, 1943, 1945 and 1952 were reproduced, as well as hypothetical floods at different periods of the year. Tests on individual problems were conducted until 1971 but high costs and growth of computer modelling meant that the facility was put on standby. The last use was in 1973, when a potentially catastrophic failure arose at the Old River Control Structure. The model was used to show that the untested Morganza Spillway could be opened effectively, without diverting polluted water through New Orleans and Baton Rouge, as well as identifying levees that required topping up. In 1993 the site was taken
