Map shows approximate inundation areas for given water surface elevations and should not be used for navigation or permitting or other legal purposes, but strictly as a planning reference tool.

Flood Impacts Collapse

54.4 Catastrophic flooding occurrs with water overtopping numerous levees in the Monroe area. High water laps at the bottom of the U.S. Highway 80 bridge.
49 Major flooding between the levees occurs and the floodwall gap must be closed on the East Monroe side of the river.
47.5 Water floods the underclearance of the Desiard Street bridge. Major lowland flooding occurs between the levee systems.
45 The Prairon Bayou recreational area floods and closes. Lowland flooding becomes extensive at this stage between levees.
43 The Bawcomville and Moon Lake recreational areas flood and close.
40 Minor backwater flooding affects small bayous that drain into the Ouachita River along with minor lowland flooding between levee systems.
36 Both the Forsythe and Lazarre recreational areas flood and close with very minor lowland flooding immediately next to the river.
34 The Forsythe Recreational Area closes, otherwise no other flooding occurs in the Monroe area until a stage of 36 feet.
