According to a past issue of "The Splash," the official publication of the National Fresh Water Fishing Hall of Fame, the following are safety, ice-thickness guidelines to be considered before venturing out.
Always remember that currents under the ice and slush on the ice may effect the thickness.
Here are the guidelines:
Blue, clear ice is safer than cloudy ice.
One inch of ice: Stay off.
Two to three inches of clear, blue ice: Will support one adult walking.
Four inches: Needed for safe ice fishing.
Five inches: Needed for snowmobiling.
Eight inches: Needed to support the weight of a car or a light truck.
Ten inches: Needed to support the weight of a medium-weight truck.
At all times, be careful out there. When in doubt, don't go out.
