The annual Port Huron Float Down hits the St Clair River this weekend.
Both American and Canadian Coast Guard officials are warning participants to use extreme caution ahead of the unsanctioned event, set to take place on Sunday.
In a joint statement, authorities say high risk factors include the fast-moving current, weather conditions, water temperature, the large number of participants, lack of life jackets, and alcohol consumption. These factors can create challenging emergency response scenarios that can result in serious injuries or fatalities.
“This is an inherently dangerous activity,” the joint statement reads. “As first responders, the U.S. Coast Guard and the Canadian Coast Guard recommend that people do not take part in this event.”
Those who choose to take part are strongly encouraged to wear an appropriately sized floatation device, don’t drink alcohol, file a ‘float plan’ with someone on shore who can keep track of you in case you don’t check in on time, and stay near shore and out of the navigation channel.
While many consider it a fun way to spend a summer day, the Float Down has had some serious issues in the past. In 2014 a 19-year-old experienced swimmer drowned during the event. Two years later, high winds and heavy rain stranded roughly 1500 participants on the Canadian side of the border without any ID or means of communication. Some were hurt while others were suffering from hypothermia.
Authorities say the St Clair River will be closed to commercial and recreational vessel traffic from 12pm until 7pm on Sunday to ensure everyone’s safety.
