U.S., Canadian Coast Guards Warn Against Dangerous Port Huron Float Down

The Port Huron Float Down, an unsanctioned event where thousands float down the St. Clair River on various inflatables, is scheduled for August 17, 2025, but authorities strongly advise against participation due to significant safety risks. The U.S. and Canadian Coast Guards issued joint warnings highlighting dangers such as fast currents, cold water temperatures, unpredictable weather, and previous incidents including a fatal drowning in 2014 and mass rescues in 2016. Both coast guards recommend precautions for those who choose to participate, including wearing approved life jackets, not going alone, staying near shore, and marking flotation devices with contact information. Transport Canada announced temporary vessel traffic restrictions on the Canadian side of the river during the event to enhance safety and prevent collisions. Officials emphasize the event's inherent risks and the potential for serious injury or fatality, urging floaters to take safety seriously and comply with regulations. The float down continues to attract large crowds despite these warnings, underscoring ongoing challenges for emergency responders and border security due to the river's international boundary location.
