Never assume that any ice is ever safe
The public is urged to practice ice safety on all of Wisconsin’s waterbodies, and to remember that no ice is safe ice. Frigid overnight temperatures often leave a thin layer of ice across smaller bodies of water, but that ice is not strong enough to support the weight of a person or machine.
“After we have these first cold nights, we start to see the early ice forming,” said Lt. Jacob Holsclaw, DNR off-highway vehicle administrator. “It may look solid to the naked eye, but it’s not. There can be cracks and changes in the ice thickness that you won’t see until it’s too late.”
Temperature swings, strong winds, currents, underground springs feeding lakes and rivers, vary widely across Wisconsin, and even across a given lake or river. These factors and more are why no ice is ever considered safe, especially not this early in the season.
The DNR does not monitor ice conditions. If plans include access to, or use of, an ice-covered waterbody, contact local fishing clubs, bait shops or outfitters for ice conditions.
“These places routinely check ice conditions, and can give you the best and most current conditions,” said Holsclaw. “If you can plan your outing without any travel over ice, do it. And if you are going to be on some ice, let someone know your plans and follow them.”
Each waterbody can have its own characteristics. Check if the lake has inlets, outlets, narrows that have currents or is spring-fed, all of which can thin the ice. Some smaller lakes can have aerators that are run throughout the winter, either covering a large area toward the center of the lake or may have smaller aerators placed by private property landowners, adjacent to their shore and piers.
It is equally as important to stay alert for pressure ridges or ice heaves. These can be dangerous, because of thin ice and resulting open water. They are often created, move or grow, with changes in temperatures and high winds.
It’s important to remember a few safety tips, before starting out:
• Carry a cell phone, and let people know the destination and return time.
• Wear proper clothing and equipment, including a life jacket or a float coat, to help stay afloat and to help maintain body heat.
• Wear ice 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 few spikes and a length of light rope in an easily accessible pocket, to help pull oneself – or others – out of the ice.
• If a fall through the ice does happen, remain as calm as possible. While attempting to get out of the water, call for help. Anyone who attempts a rescue should use a rope or something similar to avoid falling through themselves.
• Do not travel in unfamiliar areas or at night.
