McCrea is famous as the location of the last levee breach or " crevasse " of the Great Flood of 1927 . As the high water of that year accumulated within the Atchafalaya River to unprecedented heights , authorities were concerned that the Mississippi River itself was attempting to shift its channel into that of the Atchafalaya . Some 2,000 men - free labor and state convicts - labored for weeks under government supervision to prevent a breach , but the McCrea levee broke at 3:15 a.m. on May 24 , flooding much of Pointe Coupee , West Baton Rouge , Iberville and Assumption Parishes and forcing more than 10,000 residents from their homes
