First off, my prayers go out to the two boys and their families.
I personally won't go out onto the ice unless it's 5 to 6 inches thick. Water does not freeze evenly all the time. Many things can affect how it freezes, such as water depth, contour, water current, water temperature, water density underground springs, run off, stress on the ice, weather, and floating debris. Always check before venturing out onto the ice. Do not assume, because others are out on the ice that it is safe to be out there!
Prepare for the worst:
Ask around about how thick the ice is
Was the ice checked for thickness by authorizes
Obey posted warning signs
Make a test hole near shore to verify thickness
Don’t venture out on the ice without …
A pair of ice claws
Glow stick
Whistle
Optional – Inflatable belt or vest
Enjoy the great outdoors this winter and be safe.
