Central Alberta residents are urged to stay off unstable ice as temperatures fluctuate, creating hazardous conditions on lakes, rivers, and stormwater ponds.
The warning comes after Nanton RCMP responded to an incident on Sunday at Chain Lakes Reservoir, where an ice fishing structure broke through the ice.
A vehicle carrying several people was on the same section of ice, attempting to recover the structure.
"Nanton RCMP would like to remind the community that entry onto the lake ice at this time of year could be potentially dangerous, and checking ice conditions is recommended," RCMP said in a statement.
They emphasized that, beyond personal risk, dangerous ice conditions also put first responders at unnecessary risk if a rescue is required.
Ice conditions are expected to become even more unstable, with temperatures swinging from below freezing to above zero over the coming days.
RCMP warn that shifting temperatures weaken ice unpredictably, making it difficult to assess whether a surface is safe. They advise checking ice depth before venturing out, informing someone of travel plans, and being aware of aerated lakes.
Carrying safety gear, such as ice picks, flotation devices, and warm, identifiable clothing, can improve safety and visibility in case of an emergency.
The Alberta Conservation Association (ACA) warns that many lakes across the province have surface aerators running to prevent winter fish kills, creating thin ice and open water.
ACA advises people to look for danger signs posted at these lakes and avoid areas with open water. Ice thickness and strength can vary due to fluctuating temperatures, moving water, and road runoff.
Those venturing onto the ice should avoid inlets, outlets, and areas with visible cracks. If driving, they should keep seat belts off, crack a window, and unlatch doors for a quick exit. Anyone who falls through should crawl onto the ice on their belly to spread their weight and seek warmth immediately, as hypothermia can set in quickly.
Alberta regulations require ice fishing shelters left on the ice for more than 24 hours to be labeled with either a Wildlife Identification Number (WIN) or the owner’s name and phone number. Ice huts must be removed by March 15 in Fisheries Management Area PP1 and by March 31 in PP2, ES1-ES4, and NB1-NB4.
If a break-up occurs earlier, fishery officers may require immediate removal. Abandoned ice huts can pollute lakes and pose a hazard to fish populations.
Officials stress that no ice surface is ever completely safe. With temperatures fluctuating throughout the week, residents are urged to use extreme caution and avoid venturing onto questionable ice.
