        Frequently Asked Questions

    • Levee failures: The Mississippi and Missouri rivers' levee system, which had been weakened by years of overtopping and seepage, collapsed under the pressure of the water, allowing the floodwaters to spread.
    • The Great Flood of 1927 occurred in April 1927, affecting seven states in the Mississippi River basin, including Arkansas, Illinois, Iowa, Kentucky, Louisiana, Mississippi, and Tennessee. Heavy rainfall, combined with snowmelt and a failure of the Mississippi and Missouri rivers' levee system, caused widespread flooding that displaced over 640,000 people and resulted in 246 deaths. The economic impact was severe, with damages estimated at $1 billion (approximately $15 billion in today's dollars).
