Mississippi faces severe flood risk from the Mississippi River, Pearl River, Tombigbee River, and coastal storm surge along the Gulf Coast. The state has experienced some of the most devastating floods in American history including the Great Mississippi Flood of 1927 which inundated over 700,000 homes. The 2011 Mississippi River flood tested the state's flood protection systems to their limits with thousands of acres intentionally flooded to protect populated areas. Jackson sits along the Pearl River which regularly floods. The 2020 Pearl River flood inundated portions of downtown Jackson and caused hundreds of millions in damage. The Yazoo River basin in the Mississippi Delta faces chronic flooding affecting agricultural operations and small communities. The Gulf Coast counties of Hancock, Harrison, and Jackson face hurricane storm surge. Hurricane Katrina caused over $120 billion in damage to Mississippi's coast in 2005 with storm surge reaching 30 feet. The state has over 300 NFIP-participating communities and has received over $5 billion in FEMA flood-related disaster declarations since 2000.
