On May 3, 1849, a Mississippi River levee breach upriver from the city (around modern River Ridge, Louisiana) created the worst flooding the city had ever seen. The flood, known as at Sauvé's Crevasse, left 12,000 people homeless. While New Orleans has experienced numerous floods large and small in its history, the flood of 1849 was of a more disastrous scale than any save the flooding after Hurricane Katrina in 2005. New Orleans has not experienced flooding from the Mississippi River since Sauvé's Crevasse, although it came dangerously close during the Great Mississippi Flood of 1927.
