Thin ice likely; caution urged
On the Great Lakes, offshore winds can break off miles-wide pans of ice stranding large numbers of fishermen (File photo)
Ice does not freeze at a uniform thickness across most lakes and rivers, particularly in the early winter when near-shore ice is often much thicker and safer than ice further out.
And ice that has formed over flowing water, springs, pressure cracks, old ice holes or around the mouths of rivers and streams can be weaker than surrounding ice.
Police say parents should be mindful that children and pets may venture out on frozen ponds, ditches or waterways thinking they are safe with tragic results.
