21.27 Flood or Record occurred on April 25, 1922.
20 A 20 foot project levee protects the city. Floodwalls and levees are constantly upgraded to maintain that project height.
17 The river level will continue making navigation and docking difficult. The city is protected to a project height of 20 feet.
13 Strong eddies will develop below the gage at Carrollton, with increased negative impacts on navigation.
