The government of Saskatchewan is reminding the public to practice caution when ice fishing or enjoying winter activities this winter.
Ice thickness depends on the body of water and surround conditions, so it does not freeze at a consistent thickness and can vary in strength from one area to another.
The Ministry of Environment is cautioning people to test the ice thickness before traveling on it.
There should be at least 10 cm (4 inches) of ice to walk on ice, 15 cm (6 inches) to drive a snowmobile or ATV, 20 cm (8 inches) to drive a car or light truck, and 30 cm (12 inches) to drive a heavy truck.
The ministry warns that clear, hard ice is the only ice that is recommended to travel on.
People should avoid ice that:
• is slushy in appearance;
• has thawed then froze again;
• is near moving water;
• is layered, caused by sudden temperature changes; and
• has structures on it, such as pressure ridges.
