In the Quad Cities, the Mississippi River will begin to crest one week from today.

The National Weather Service in Davenport says even if more rain and snow fall up north, it'll be too late affect the crest here.

Hydologist Matt Wilson says recent precipitation from Minnesota and Wisconsin could prolong the time it takes for the Mississippi to recede. Also, a weather system in the southwest should help keep Iowa and Illinois dry for the next week.

"It's going to kind of cut our area off from moisture for at least seven days, hopefully a little bit longer. That could allow us some time to push this snow melt crest through our area and before we get any significant rainfall on top of it. That's our that's our good news for the day."

During today's web briefing, Hydologist Matt Wilson said the river at Lock and Dam 15 in the Quad Cities reached major flood stage.

"Within a few hours of when I created this, we're pretty on point for 18 feet. So I can at least forecast a couple hours in advance. And we are expecting it to get to 21.7 by the morning of May 1st. That's going to be near the crest. That should continue to rise, but slowly, for a few days after that."

Wilson says high water on the Mississippi is starting to cause backwaters to rise into local tributaries. That includes the Wapsipinicon River near DeWitt and Rock at Moline and Joslin, which may reach flood stage.

He calls it a "backwater effect," and does not expect it to cause any major flooding, just "nuisance high water."
