How much is ‘safe’ ice?

I have received several requests from people asking me about “safe” ice. I guess several folks are anticipating the chance to go ice fishing, and several people received new ice skates for Christmas gifts. They want to know about going ice skating on farm ponds, retention ponds, and maybe even skating on some creeks behind their house.

As a rule of thumb, I would never trust two inches of ice, and four inches of ice is the minimum required for walking and ice fishing. Five or six inches of ice is preferred for snowmobiles and ATVs. Eight to 12 inches of ice are needed for cars and small trucks, and 12 to 15 inches are needed for medium-sized trucks.

A good source of information is a local bait and tackle store. Ask for any ice thickness information they might know. Before venturing onto the ice, be sure to have the proper safety equipment. Also, use a spud bar or other tools to test the ice as you walk.

It is advisable to never venture out alone. If you fall through the ice, a companion can toss you a rope to assist you getting out of the frozen water. It is very important to dress warmly and have ice cleats on your boots to help prevent slipping and falling. A good pair of Mickey Mouse boots and warm, insulated socks can help keep your feet warm.

Snowmobile suits or a good pair of insulated Carhartt bibs, a warm, thick sweatshirt, and a hooded parka can really keep you warm. Also, it is not a bad idea to have an extra change of clothes in your truck. That can be a blessing as well. Warm gloves and handwarmers are fantastic, too.



If you are ice fishing, a portable, fold-down, fishing shelter can be a lifesaver, preventing the cold wind from chilling you to the bone. I used to carry a simple boat cushion attached to a 30-foot length of rope in case someone fell through the ice. I could toss the cushion to them and pull them out.

I also had a homemade pair of ice picks that were attached with a length of string in case I fell through. I could use the picks to jab into the ice and help me climb out of the water. A good heater or butane lantern can be a lifesaver for helping you get warm.

You might want to find out if there are any inlets or outlets to the body of water you are skating on or ice fishing. These inlets and outlets can affect ice thickness in a very short period of time. Don't be afraid to ask people on the body of water about current conditions. Most people are willing to share information with you. It is usually more enjoyable when you are ice skating or ice fishing with several people around you. Safety in numbers is advisable.
