The United States Coast Guard has changed its stance and is now allowing recreational boating on the Mississippi River, but still recommends boaters stay off the water.
In their most recent update, the Coast Guard changed from prohibiting to now Strongly Discouraging boating on river in the Dubuque pool and all others still experiencing flooding conditions. In a message on the Coast Guard social media, they say after speaking to port partners and government agencies along the river, they are no longer prohibiting recreational boating in the pools in the High Water Action Phase at this time however recreational boating is now strongly discouraged.
The Coast Guard had prohibited recreational boating on the Mississippi since July 3rd when the action was taken.
