(Dubuque, IA) -- The U.S. Coast Guard in Dubuque is stuck in port.
They can't deploy on the Mississippi River due to the closure of the port's floodgates.
The Coast Guard maintains navigation aids along the Mississippi from Dubuque to St. Paul.
There is concern about the safety of boaters over the Independence Day holiday with high water and debris on the river.
Once the floodgates reopen, the Coast Guard anticipates significant work to repair and secure areas affected by the flooding.
