Elliot City, Louisiana City was abandoned in 1939 when its residents were forced to leave due to the construction of the Morganza Spillway. This area is inside the floodway levee system and was entirely underwater when the floodway gates at the Morganza control structure were opened in 1973 and 2011 to relieve the high water level of the Mississippi River.
