Early in the morning on April 22nd, 1927, flood waters from a break in the Mound Landing levee entered the town of Greenville, Mississippi. Within hours, the town was submerged in 10 feet of water. Thousands of residents fought to reach higher ground, desperately clinging to tree tops and floating houses.The flood inundated 27,000 square miles in seven states.
