The Mississippi River flood of 2018 was one of the most devastating floods in United States history. It caused an estimated $25 billion in economic damage and affected an estimated total of 66 million people in seven states, stretching from Ohio to Louisiana. In addition to major property damage, the floods resulted in a loss of human life, including 19 people along the Mississippi River alone. <\/p>\n

Tennessee, Arkansas, Mississippi and Louisiana were the states that felt the worst effects of the floods. Record-breaking peak discharges caused extensive flooding along the entire length of the river. In Arkansas, extreme flooding caused the displacement of 1,400 people and the evacuation of several communities. <\/p>\n

To assess just how much water the Mississippi during this flood, experts from the National Oceanic and Atmospheric Administration as well as the United States Geological Survey utilized remote sensing and modeling technology to measure flooding impacts, flood depths, and more. Areas most impacted by the floods were in the Lower Mississippi Basin and earthen levees along the River reached peak discharges of more than 200,000 cubic feet per second. Effects from the flooding were felt downstream from Cairo, Illinois to the Gulf of Mexico, with regions impacted most suffering from peak discharges over three times the long-term average.<\/p>\n

The flooding of the Mississippi River is the direct result of its expansive size, complex network of tributaries, and the presence of densely populated towns and cities situated in low-lying areas. With 460,000 square miles of drainage area, the Upper Mississippi stretches from Minnesota to Missouri and is the second largest river system in North America. The Lower Mississippi basin alone stretches from St. Louis to the Gulf of Mexico and is by far the largest tributary region in terms of size and population, with a drainage area of 184,000 square miles. <\/p>\n
