With recent warmer temperatures settling over the West Country, Clearwater Regional Fire Rescue Services (CRFRS) is issuing a reminder to the public: it is never safe to venture out onto the ice of the North Saskatchewan River.

Officials say there is no safe thickness for river ice, as the movement of the river itself can lead to thinner spots, undercuts, and ice bridges that collapse unexpectedly. Officials say warmer temperatures in recent weeks have only heightened these risks, making even slower-moving rivers more hazardous.

While venturing out on to the river is unsafe, officials say you should be aware of ice thickness before heading out on to any lake surface- especially with the warmer weather.

Michael VanderBaaren, Fire Prevention Officer with CRFRS, noted that the minimum ice thickness for safe activities can vary. For example, walking on clear ice requires a minimum thickness of 10 cm, snowmobiles demand at least 20 cm, and light vehicles need 40 cm of solid ice. However, these guidelines are not applicable to river ice, where the risk remains unpredictable.

VanderBaaren further warned against the dangers of “snow ice,” the weak, snow-covered ice that is up to 50 percent less stable than clear ice.

In the event of an ice emergency, VanderBaaren emphasized that the top priority is securing the airway of anyone who falls through the ice to prevent drowning. “You’re more likely to drown before you freeze,” he said. “If you or someone else falls through the ice, remain calm, get your arms out onto the ice, and immediately call for help. It’s also safest to travel in pairs or groups.”

Although ice rescue calls in the region are rare, VanderBaaren urged the public to recognize that rivers are a far greater hazard, given their dynamic nature. He highlighted that ice on rivers can form pockets of weak or broken sections, making each step more dangerous.

Locally, officials in Rocky Mountain House are also working to raise awareness. The Credit Union Co-op Aquatic Centre has an ongoing ice safety display for residents to learn about winter hazards.

Town officials remind residents that storm retention ponds around town are never safe for ice activities, and all safety signs should be obeyed.
