City of Prairie du Chien Flood Update 4/20/23

Mayor Dave Hemmer announced last night due to the faster rise of the river than expected that St. Feriole Island was closed to all traffic. The latest projections from the National Weather Service have the river reaching a level at or near 23.6 feet early by Thursday, April 27. This level would be .5 higher than the flood of 2001. City and County officials again met this morning and will be having a Public Information Meeting tomorrow April 21, 2023 at 1:30 P.M. in the Community Room at City Hall.

Evacuation sites are being prepared for those who wish to use them if they experience flood water in their residence. Additional information to follow at the PIM. In the event a resident decides to evacuate please contact Madison Gas and Electric and Alliant Energy.

As the river continues to rise, we encourage pedestrians not to walk on St. Feriole Island.

Due to a higher predicted river stage, the wastewater department is asking that all people that are or will be receiving flood water in their basement, that they place a plastic bag and a couple of sandbags over their floor drain to prevent flood waters from entering the sanitary sewer line. Sandbags are available to be picked up at the corner of N. Ohio St. and E. Washington St. or those who need sandbags and have no reasonable means of picking them up contact the WWTF at 608-326-8534 or Crawford County EOC at 608-326-0266 for assistance.

A slow no-wake will be in effect as well in all flooded navigable waters in the City of Prairie du Chien.
