What caused the Great Mississippi Flood of 1927? The Great Mississippi Flood of 1927 was one of the most devastating natural disasters in U.S. history. Heavy rainfall in the central basin of the Mississippi River, combined with snowmelt from the north, led to the river's levels rising dramatically. Levee failures played a significant role, as many of these structures were unable to withstand the immense pressure from the swollen river. The floodwaters spread across 27,000 square miles, affecting hundreds of thousands of people. This catastrophe not only reshaped the landscape but also had lasting impacts on flood control policies and civil rights movements in the United States.
