Heavy rain this week is causing some high water along the Mississippi River.
In Hannibal, the river reached technical flood stage Friday morning. According to the National Weather Service (NWS), the river hit 16 feet at 8:15 a.m.
The river was still rising Friday afternoon. It is projected to crest at 17.8 feet in Hannibal around 2 a.m. Monday, according to the NWS. Barring additional precipitation, the river is then expected to begin a slow decline into the week ahead. However, additional rain is forecast beginning Sunday night. Rain is a part of the NWS’ forecast for the Hannibal area every day through Thursday.
Capt. Steve Terry, owner of the Mark Twain Riverboat, termed what Hannibal is experiencing as nothing more than “high water.”
“I know it’s technical flood stage, but look around. It’s not impacting anything,” he said.
Terry said he doesn’t consider it flooding until the river reaches 18 or 19 feet and begins impacting parking along the riverfront.
Unless the river forecast is revised higher, little prep work will need to be done in Hannibal to keep the river at bay. Typically the city closes gate wells at Center Street and the pump station so the river can’t back up into those storm sewers.
The flood gates at Hill and Center streets would not be set until the river is predicted to reach at least 20 feet. The remaining three gates would only go in if the river is forecast to hit 21 feet or higher.
It was just one month ago that the river crept past technical flood stage in Hannibal before cresting just over 18 feet on March 14.
The latest river rise was fueled by Wednesday’s storm system which dumped 1 to 2 inches of rain on portions of the Midwest.
In addition to Hannibal, the NWS’ flood warning also includes Saverton Lock & Dam 22, Louisiana and Clarksville Lock & Dam 24. Minor flooding will begin in Saverton Saturday afternoon when the river reaches 16 feet. In Louisiana, minor flooding should begin Friday night when the river stage hits 15 feet. In Clarksville, minor flooding begins at 25 feet. It’s forecast to reach that height Friday evening.
No significant damage is expected along the Mississippi, but thousands of acres of farmland and some rural roads will be under water.
