If you head out to one of Wisconsin's many lakes or rivers to ice fish, snowmobile, ATV, cross-country ski, or just to enjoy a winter day, we want you to have fun and be safe. A bit of advance planning and practicing basic ice precautions can help you return home safely.
There really is no sure answer, and no such thing as 100 percent safe ice. You cannot judge the strength of ice by one factor like its appearance, age, thickness, temperature or whether the ice is covered with snow. Ice strength is based on a combination of several factors, and they can vary from water body to water body. Ice strength can also vary in different areas of the same body of water.
Because ice conditions vary, it is important to know before you go. The DNR does not monitor local ice conditions or the thickness of the ice. Local bait shops, fishing clubs and resorts serve winter anglers every day and often have the most up-to-date information on how thick the ice is on local lakes and rivers, as well as areas that are especially dangerous.
If you fall through the ice, remain calm and act quickly.
