The province is reminding everyone to make sure that ice is safe and thick enough before walking or driving on it. Ice thickness depends on the particular waterbody and the local conditions.

As a guideline, you need at least 10 cm (four inches) of ice to walk on, 20 cm (eight inches) to drive a snowmobile or ATV on, 30 cm (12 inches) to drive a car or light truck on, and more than 30 cm (12 inches) to support a heavy truck.

Thickness is just one consideration when evaluating ice safety. Clear, hard ice is the only ice recommended for travel. Ice does not freeze at a uniform thickness and ice strength can vary considerably from one area to another.

Ice should be re-evaluated on every date visited, even if was safe on a previous date. The date ice becomes safe at a site varies from year to year requiring the verification of the thickness each year as opposed to relying on past experiences.

Also avoid ice that:
looks slushy;
has thawed, then frozen again;
is near moving water;
is layered, caused by sudden temperature changes; or
has structures on it, such as pressure ridges.

In comparison to lake ice, river ice is often more hazardous and inconsistent, particularly downstream of dams when winter releases are being made. The Water Security Agency is currently releasing water from Reid Lake on Swift Current Creek and there is also flow throughout the Qu’Appelle and Saskatchewan river systems. These flows would impact the formation of the ice covers and these areas should be avoided as conditions can change significantly over short distances.
