City of Dubuque Closely Watching Mississippi River

The City of Dubuque is closely monitoring the Mississippi River level and the John C. Culver Floodwall as the river is expected to crest at 24’9” on Sunday.  This latest projection from the National Weather Service would be the third highest in recorded history behind 1965 and 2001. The floodwall/levee protecting most of the city is operating as designed and City staff are now monitoring it around the clock for any signs of issues.  Public Works staff have also closed 13 of the 17 floodgates along the river and are operating four permanent pumping stations and three temporary pumps 24/7 to convey water over the floodwall and into the river.  The remaining gates will be closed before the end of the week, based on current information. This will be just the third time all the flood gates have been closed since the flood control system was completed in 1973.
