Historic flooding is possible in the Quad Cities next month.

Our flood season is about to go from bad to worse, and it could be one for the record books along the Mississippi River.

UPDATE: Rock River expected to break record flood crest this weekend

We’ve had above average rain every month since last May and our soil is saturated throughout the area.  Combine that with heavy snowpack to the North (which will soon be melting) and we’re looking at prime conditions for major flooding.   

Hydrologists with the National Weather Service are indicating a 25-50% chance that we could see the highest water level ever on the Mississippi River in the Quad Cities next month. 

That’s right, it could be worse than the 22.63′ crest on July 9th, 1993.

This chart shows the probabilities of reaching different levels on the river in the Quad Cities.We already have several rivers under flood warnings, and we’ll see all area rivers flood eventually this season.  The flooding on the Mississippi River in the Quad Cities looks to begin later this week.  Here’s the forecast from the NWS: As of Wednesday night the river stands at 10.9′ in the Quad Cities.  That’s below flood stage.  It doesn’t stay this way long though, we’re looking at the first of several different crests this season coming up this weekend.  This time around we’ll rapidly climb to 18.2′ by Sunday and have our first major flood of the year. 

And this will be a long duration event.  We’ll likely see rivers in some form of flood stage from now until late April or May.  

According to the NWS, here’s a look at the top Mississippi River crests ever in the Quad Cities:

Historic Crests
(1) 22.63 ft on 07/09/1993
(2) 22.48 ft on 04/28/1965
(3) 22.33 ft on 04/25/2001
(4) 22.00 ft on 03/10/1868
(5) 21.49 ft on 06/16/2008
(6) 20.94 ft on 07/04/2014 (Preliminary)
(7) 20.71 ft on 04/22/2011
(8) 19.66 ft on 04/20/1997
(9) 19.40 ft on 06/27/1892
(10) 19.30 ft on 04/26/1969

This will be an ongoing issue for the next few months and we’ll update the situation often, as we could be looking at the worst flood ever in the Quad Cities within the next 6 or 7 weeks.
