Areas with frozen lakes, ponds, canals, and reservoirs can be beautiful places to visit during the winter months but all too often many people risk their lives by venturing onto frozen water. Playing on the frozen edges of a pond, lake or canal is perilous as ice can be quite thick in one area yet it can be much thinner close to that same area.
- Walking on ice is extremely risky and unpredictable. If you do fall through, the freezing water temperatures can very quickly bring on cold water shock.
- Teach children not to go onto the ice under any circumstances.
- Don’t go onto ice or into the water to rescue a dog, move to somewhere that the dog will be able to climb out and call them towards you.
- Keep dogs on their leads when near ice and don’t throw sticks or toys onto the ice.
- Many factors affect ice thickness including: type of water, location, the time of year, shade from the sun and other environmental factors such as:
- Water depth and size of body of water.
- Currents, tides, and other moving water.
- Chemicals including salt.
- Fluctuations in water levels.
- Logs, rocks, and docks absorbing heat from the sun.
- Changing air temperature.
- Shock waves from vehicles traveling on the ice.
Ice Colour: The colour of ice may be an indication of its strength. Clear blue ice is strongest. White opaque or snow ice is half as strong as blue ice. Opaque ice is formed by wet snow freezing on the ice. Grey ice is unsafe.
