The most notable of these was on August 17-18, 1969, when Hurricane Camille produced all-time record tidal floods along the Mississippi coast and killed 137 people and caused more than 510 million dollars in damage (U.S. Army Corps of Engineers, 1970). Greater-than-50-year floods occurred on small streams in Wilkinson County as the result of 12 inches of rain on July 19 and 8 inches on July 23, 1969. Comparatively low floods occurred on the Tombigbee River at Columbus on July 8-9, 1968, although the 24-hour total rainfall of 16 inches there was the greatest ever recorded in Mississippi. Split storm periods and the rapid dissipation of the floodflows of small streams draining into the Tombigbee River help to explain the minor flooding resulting from the intense rainfall.
