*Many residents on our lake have bubblers which can weaken the ice >150 feet away depending on the flow. If you have one, please clearly indicate to minimize risk for all those out on the ice (fisherman, snowmobiles, snowshoers, skiers, etc).
*Never go onto the ice alone. A friend may be able to rescue you or get help.
*Always keep your pets on a leash. If a pet falls through the ice do not attempt to rescue, go for help.
*New ice is usually stronger than old. As the ice ages, the bond between the crystals decays, making it weaker, even if melting has not occurred.
*Beware of ice covered with snow. Snow can insulate ice and keep it strong, but can also keep it from freezing. Snow can also hide cracks, weak, or open ice.
*Slush is a danger sign that ice can be weak or deteriorating.
*Ice formed over flowing water (containing a large number of springs) is generally 15% weaker.
*Ice seldom freezes or thaws at a uniform rate. It can be one foot thick and one inch thick 10 feet apart.
