The Mississippi River is a is the widest river in the United States. It’s mere size and the amount of water in it, makes one expect that at some point, it is going to flood. In fact, it has flooded many times over the years, but none was anything like the Great Mississippi Flood of 1927. It was the most destructive river flood in the history of the United States. In all, 27,000 square miles of land were inundated with water up to a 30 feet depth. In all, 630,000 people were affected by the flood. About 94% of them lived in the states of Arkansas, Mississippi, and Louisiana, most in the Mississippi Delta. At least 15 inches of rain fell in 18 hours causing the Mississippi River to brake out of its levee system at 145 locations. Ten states were affected…Arkansas, Illinois, Kentucky, Louisiana, Mississippi, Missouri, Tennessee, Texas, Oklahoma, and Kansas. Arkansas was the worst affected with 14% of the state flooded.
It was Good Friday, April 15, 1927, the disaster began when 15 inches of rain fell in New Orleans in 18 hours. More than 4 feet of water covered parts of the city. A group of influential bankers in town met to discuss how to guarantee the safety of the city, as they had already learned of the massive scale of flooding upriver. A few weeks after, they arranged to set off about 30 tons of dynamite on the levee at Caernarvon, in an effort to flood a less populated area and save the cities that would have been severely damaged. I’m not sure how much this effort helped, and in the end, about 500 people lost their lives anyway. It wouldn’t be the last Mississippi River flood, but it would be the worst.
As a result of the flooding, many of the misplaced people joined the Great Migration from the south to northern and midwestern industrial cities rather than return to rural agricultural labor. I would think that the idea of such a massive amount of cleanup would be more than many people could take. This massive population movement increased from World War II until 1970. Of course, this volume of population movement would not be good for the states who were losing people. To try to prevent future floods, the federal government built the world’s longest system of levees and floodways. By August 1927, when the flood subsided, hundreds of thousands of people had been made homeless and displaced; properties, livestock and crops were destroyed. Flooding on the Mississippi is not an unusual event, and no matter how many precautions we take, there will still be losses when the river overflows its banks.
