Heavy Rain Turns to Flooding

Heavy rain in north central Iowa this afternoon fell in the Cedar River basin. The 4-6″ of rain is enough for the river to rise pretty quickly and above flood stage. The image below shows where the radar estimates the heaviest rain to have fallen. Click here for the Cedar River forecast. If you want to see other rivers…there is a button on the right side of the blog that says “River Levels”.

Here are some rain totals I have found in eastern Iowa:
Osage: 4.20
Charles City: 2.18
Ionia: 2.15
Fairbank: 1.90
West Union: 1.63
Cresco: 0.82
Denver: 0.73
Waukon: 0.70
Harpers Ferry: 0.46
Arlington: 0.31
Guttenberg: 0.30″
Waverly: 0.24
Monona: 0.22

Flood Gages May be Discontinued in Iowa

Potential budget cuts in future years may result in the discontinuation of flood gages in the Mississippi River basin in Iowa, including central and eastern Iowa.  Any flood gage discontinuations may severely impact the National Weather Service’s ability to forecast and detect floods.

These flood gages are used not only by the National Weather Service, but also the U.S. Geological Survey, the U.S. Army Corps of Engineers, the Iowa Department of Transportation, natural resources agencies, emergency management agencies and water intake owners such as municipal water supply, and power plants.

Many of the flood gages in central and eastern Iowa are funded by various partners in the public and private sectors, including the U.S. Geological Survey, Iowa Water Science Center and the U.S. Army Corps of Engineers, Rock Island District.

Please join us, the U.S. Geological Survey and the U.S. Army Corps of Engineers from 1-4 pm CDT on Tuesday, June 7, 2011 in Iowa City, IA to discuss these issues and identify potential solutions. We will meet at the Iowa National Guard Readiness center at 4540 Melrose Ave, Iowa City, IA.  Click here to see this location in Google Maps.

You can find more details on this meeting, as well as location and driving directions by downloading this flyer.  We hope to see you there!

 

If you have any questions, please contact:
