The weather forecast Sunday didn't stop everyone from taking part in the 45th annual Port Huron Float Down.
Authorities estimate that between 500 and 1,000 participants entered the river at Lighthouse Beach in Port Huron, Michigan.
Canadian Coast Guard Incident Commander Kathleen Getty said it was a quiet event compared to years past.
"I think with the storms rolling in before the event, I think that made people sort of leery about getting out on the water this year," said Getty. "There was no significant events that occurred and it was fairly quiet."
In previous years, upwards of 5,000 people have taken part in the 12 kilometre float down.

Sarnia police said no arrests were made and there were no medical issues reported on this side of the border.
The U.S. Coast Guard, Royal Canadian Mounted Police (RCMP), Canada Border Services Agency (CBSA), Ontario Provincial Police, and Sarnia Fire and Rescue were also patrolling during the float down.
Vessel traffic on the St. Clair River was restricted from the Blue Water Bridge to the upper end of Stag Island during the event.
In 2016, a wind shift sent some 1,500 floaters to the Canadian shore, most of them Americans without proper identification. They had to be rounded up, processed by Canadian authorities and transported back to Michigan.
In 2014 a 19-year-old Michigan man drowned during the float down.
