The Mississippi River, which is flooding parts of Davenport, is expected to crest Tuesday morning, according to the National Weather Service.
“The walkways are flooded between the boat and the (Modern Woodmen) baseball field,” Davenport Police Sgt. Michael Murphy said Sunday night.
According to meteorologist Tim Gross with the National Weather Service, Davenport, the Mississippi River measured 15.5 feet at 6 p.m. Sunday, past its 15-feet flood stage.
On Sunday night, spotty flooding affected all of Concord Street, Murphy said.
“Water affects several sections of South Concord south of River Drive, and is at the foundations of several homes on Enchanted Island,” Murphy said. High water also affects industries along the south end of Davenport.
It takes quite a bit of time, and quite a bit of precipitation, to affect the Mississippi River, Gross said. Sunday’s rain won’t have much, if any, impact on flood levels.
“The Mississippi River is a very slow-responding river. It takes a lot of rain, particularly north of the Quad-Cities, to have any significant impact in the crest or the time of the crest,” Gross said.
Comparatively, when there are 1 or 2 inches of rain in the Cedar Rapids area or northwest of Dubuque, the Wapsipinicon River will go up at least a little bit, he said. “But if you get an inch of rain in Clinton, it’s not really going to affect the Mississippi — at least not right away.”
In the last 14 days north of the Quad-Cities, particularly in central Wisconsin, 3 to 4 inches of rain fell, Gross said. And since the March 12, a little more than 2 inches of rain fell in the Quad-Cities, he said.
Northeast Iowa and northern Illinois have received 2 to 3 inches in the last 14 days, he said. All of that rain, along with a little bit of snow that melted in Minnesota and Wisconsin, combined and finally reached the Quad-City area and the main stem of the Mississippi.
Meanwhile, the National Weather Service expects the Mississippi to crest at about 15.7 feet Tuesday morning. The river likely will stay above flood stage until Thursday morning, Gross said.
“Once it floods it stays in flood for four to seven days,” he said, again emphasizing that the river is “slow to respond.”
No flooding is expected in the other local rivers. The Rock River at Moline was at 10.9 feet Sunday night, compared to its flood stage of 12 feet. “It rose a little from the rain but will not flood,” Gross said.
And the Wapsipinicon River, at DeWitt, measured at 9.8 feet Sunday night, and flood stage is 11 feet.
A rainy Sunday will transition to a pleasant start to the work week, with mostly sunny skies and highs in the middle 50s on Monday, Gross said. Highs will be in the low 30s.
Tuesday will be sunny again, with a high in the lower 60s, and southeast winds 10-20 mph in the afternoon. Clouds will increase Tuesday night, with a chance of rain. Lows will be in the middle 40s.
More rain is expected on Wednesday, which will be breezy and cloudy. The forecast calls for a 50 percent chance of showers and thunderstorms, with highs in the middle 60s.
