False River is an oxbow lake located in southeastern Pointe Coupee Parish, Louisiana centered at 30°38′19″N 91°29′04″W / 30.63861°N 91.48444°WCoordinates: 30°38′19″N 91°29′04″W / 30.63861°N 91.48444°W This lake was once the main channel of the Mississippi River in this area. It was cut off from the "mighty Mississippi" in about 1722 when seasonal flooding cut a shorter channel to the east.
Pierre Le Moyne d'Iberville and his party bypassed False River to shorten their route up-river.
During the American Civil War, an expedition was sent from Morganza with five squadrons from the Second New York Cavalry to scout the area around the False River for Confederate recruiting officers. Marching through heavy rainstorms the expedition reached New Roads on January 31, 1865. Here five officers were found hiding in closets or under houses.
