From the record
What the reports say
Written by National Weather Service staff at the time of the event · public domain
The Mississippi River at Hannibal, MO crested at 29.54 feet on 6/18/2008. This is the second highest crest ever recorded. The City of Hannibal escaped relatively unscathed as the flood wall and most levees north and south of town held due to work by the National Guard and volunteers. Plastic and sandbags were used to raise and cover about 60% of the levees in the County. The Mark Bottoms levee was over topped resulting in 19 homes being flooded. Highway 79 in the south part of Hannibal was closed. No other towns in the county were affected as the remainder of the land along the river is used for agriculture or conservation purposes. County Extension Service personnel estimated agricultural losses at $13.3 million. Emergency management personnel reported $7.1 million in infrastructure damages.
Up to 6 inches of rain fell in a short amount of time causing flash flooding. Numerous roads were flooded including several in Hannibal. Also, Bear Creek in Hannibal overflowed its banks flooding a nearby parking lot with two feet of water and 35 to 40 residents along the creek had to be rescued from their homes by boat due to the flooding.
Thunderstorm winds flipped over a Cessna plane destroying it and damaged three other planes at the Hannibal Regional Airport. Further to the east in town, several large trees were blown over. One large tree landed on an unoccupied car causing major damage. Also, several power lines were blown down.
