DNR Urges Caution On Early Ice Covers

No Ice Is Safe Ice

By - Dec 5th, 2025 08:34 am

MADISON, Wis. – The Wisconsin Department of Natural Resources (DNR) encourages all enjoying outdoor fun this season to be extra careful on all of Wisconsin’s waterbodies and remember that no ice is safe ice.

Those eager to take advantage of winter’s snow need to keep safety at the forefront of their preparations. This includes staying alert to the rapidly changing ice conditions commonly found in the early parts of winter.

“Early in the season especially, ice conditions are unpredictable and can change quickly on Wisconsin’s rivers and lakes. The ice covers hide the currents, debris and underground springs still feeding lakes and rivers, thinning the ice in spots,” said Lt. Jacob Holsclaw, DNR Off-Highway Vehicle Administrator. “No matter if you’re on foot, on a snowmobile or in UTV, it’s important to remember that ice is never 100 percent safe.”

The DNR does not monitor ice conditions, but they are monitored locally. Local fishing clubs, outfitters and bait shops are the best sources for local current ice conditions.

However, the best idea for safe winter fun is to enjoy outings without travel over ice.

Conditions Vary Between And Across Waters

If the outing does involve travel over a waterbody, remember every waterbody has its own characteristics. Check if the lake has inlets, outlets or narrows, is spring-fed or has currents, all of which can thin the ice.

Some smaller lakes can have aerators that are run throughout the winter either covering a large area towards the center of the lake or may have smaller aerators placed by private property landowners adjacent to their shore and/or piers.

Equally as important is to stay alert for pressure ridges or ice heaves. These can be dangerous due to thin ice and open water and often are created, move or grow with changes in temperatures and high winds.

Here are more safety tips:

  • Carry a cell phone, and let people know where you are going and when you’ll return home.
  • Wear proper clothing and equipment, including a personal flotation device or a float coat to help you stay afloat and to help slow body heat loss.
  • Take an extra pair of mittens or gloves so your hands can remain dry and warm.
  • Wear creepers attached to boots to prevent slipping on clear ice.
  • Carry a spud bar to check the ice while walking to new areas.
  • Carry a couple of spikes and a length of light rope in an easily accessible pocket to help pull yourself – or others – out of the ice.
  • Do not travel in unfamiliar areas – or at night.
  • Have a plan in place noting where you will be and when you plan to return. Along with leaving a written note of your plans, it is also recommended to keep a charged cell phone.

Take Extra Care With Recreational Vehicles

Last season, several ATVs, UTVs and snowmobiles went through the ice or drove into open water, resulting in six fatalities.

Keep these safety tips in mind when operating recreational vehicles during winter.

  • Remember that UTVs are heavy. They are the heaviest recreational vehicle out on the ice, often being close to 3,000 pounds. This is similar to a car or truck.
  • Roll your window down when traveling on the ice and make sure you can easily open you door – drive slow and turn the radio down so that you can use eyes and ears to watch and hear for potential issues coming up.
  • Make sure you have life jackets or some other type of floatation for every occupant of the UTV.
  • Recovery for the UTV or other vehicle is the responsibility of the owner/operator. After 30 days, the owner can be fined each day after 30 days.
  • Recovery rates for the machine can also be very expensive.
  • Never consume alcohol or drugs before or during your ride.

Refer to the Wisconsin Snowmobile Regulations for laws for operational restrictions, safety tips and more.

The DNR also encourages all snowmobilers to take a safety education class. According to Wisconsin law, anyone at least 12 years of age and born after Jan. 1, 1985, must have a valid safety education certificate to operate a snowmobile. Sign up now as classes fill fast.

If the worst happens and you happen to fall in, here’s what to do:

  • Carry a couple of hand-held spikes and a length of light rope in an easily accessible pocket or inside your sleeves to help pull yourself – or others – out of the ice.
  • If you fall in, remain as calm as possible and while attempting to assist yourself out of the water, call for help as soon as you can. Anyone who attempts to rescue you also is recommended to use a rope or something similar to avoid falling through as well.
