Following a weekend surge, the Mississippi River in Hannibal is receding again.

Following a weekend surge, the Mississippi River in Hannibal is receding again.

Heavy rain Saturday night in northern Missouri, west-central Illinois and southern Iowa pushed the river up. The Muddy Mississippi, which had dropped from 18.48 feet on Wednesday, June 17, to 17.96 feet by 11:15 p.m. Saturday, crested again at 19.62 feet at 12:45 a.m. Monday.

It had fallen to 19.42 feet at 3:15 p.m. Monday.

The National Weather Service (NWS) was projecting a steady drop in the river level over the coming week. It is expected to slip below technical flood stage (16 feet) on Monday, June 29.

That river forecast assumes no additional heavy precipitation will fall north of the Hannibal area during the next few days. Heavy rain fell Monday in northern Iowa. More storms are predicted in eastern and southern Iowa and in northern Illinois from Wednesday through Sunday, according to the NWS.

“It concerns me a whole lot,” said John Hark, the city’s emergency management director, who was in central Iowa Monday afternoon, regarding the possibility of more precipitation. “Heavy rain is forecast tonight in Iowa. We’ll just wait and see.”

Last Wednesday, with the river projected to reach 18 feet, Street Department personnel were busy closing gate wells along the downtown flood levee.

Barring another river surge it doesn’t appear any of the city’s five flood gates will have to be installed. Only when a crest prediction of 20.5 feet or more is forecast are the gates on Hill and Center streets set. The remaining three gates - two on Broadway and one on South Main - are placed when the crest is forecast at 21.5 or more.

Unlike in recent years, it appears the flood gates will not be in place during the 2015 National Tom Sawyer Days.

In 2014, the city's five floodgates were installed on June 30 after the National Weather Service forecast a crest of 21.5. Ultimately the river reached a crest of 26.68 feet on July 8, which was the sixth highest flood crest for Hannibal in its recorded history. The gates came out last year on July 21.

Hannibal's floodgates were also in place on July 4, 2013, when the river stood at 21.88 feet.
