Bow River rescues near Canmore highlight water safety dangers as debris, melt alter channels

Eight people were pulled from the Bow River near Canmore in less than 24 hours Tuesday and Wednesday, as debris from recent flooding and swiftly melting snow created hazardous conditions that surprised even experienced paddlers.

Jeremy Mackenzie, a public safety specialist with Kananaskis Mountain Rescue, called the rescue volume "somewhat unusual" for such a short period in a single area. All rescues involved people wearing life-jackets, a critical factor in survival. "If they weren't wearing personal floatation devices, they probably wouldn't have made it," Mackenzie said.

The cascading hazards are catching paddlers off guard. One group told rescuers they had done the same trip every year for two decades without incident. "We had one group that got into trouble and they were quite surprised, because they said they had done this trip every year for the last 20 years and never had anything like this," Mackenzie said.

Tuesday's rescues involved a party of four and a group of three, with Alpine Helicopters called to rescue three people. Paramedics transported one person to hospital. Wednesday, a woman in an inflatable canoe tipped over after hitting debris. Darren Siewnarine, visiting from Calgary with his wife and a friend, heard screaming and spotted her being carried downstream. "She was bobbing in and out because of how strong the currents were. Imagine her doing that for a whole kilometre," he said. Three bystanders timed her approach and pulled her from the water.

Mackenzie stressed the 1-10-1 rule for cold water: one minute to control breathing, 10 minutes of reliable movement before cold impacts the body, and roughly an hour of survival time. "Without a life-jacket, you're often going to have some major trouble within the first 60 seconds. It's critical that people are wearing their life-jackets in these cold water environments."
