Muskego police fired off an urgent warning Sunday after several vehicles, including what the department said was a Ford Bronco, broke through the ice near shorelines on Pewaukee Lake and elsewhere in Waukesha County. According to the department, multiple motor vehicles went through the ice within roughly 50 yards of shore, a cluster of incidents that has officials telling residents to treat late-season ice as anything but reliable. Local wardens told police that warm temperatures, wind and sunny skies are already chewing up shoreline ice, turning once-safe spots into traps. First responders are urging anyone who still feels the need to go out on the ice to have a plan and proper safety gear before they even leave the house.
What Muskego police posted
In a Facebook post, the Muskego Police Department told followers to "use extreme caution when accessing lakes" and to "have a plan," stressing that shoreline ice will dissipate the fastest. Officers advised people to steer clear of ice heaves and natural springs, where ice can weaken without much warning. The department shared a photo it said showed a Ford Bronco that went through the ice on Pewaukee Lake and noted that there were multiple reports of vehicles breaking through ice close to shore over the weekend. Police also asked anyone with photos or information on similar incidents to pass them along to local authorities, according to the Muskego Police Department on Facebook.
State DNR and responders echo the danger
The Wisconsin Department of Natural Resources has repeated its standing reminder that "no ice is 100% safe" and, in a recent release, warned that late-season sun, wind and warm days can rapidly erode ice even when large stretches still look solid from shore. State wardens say anyone planning to go onto a frozen lake should first check with local lake associations, bait shops and patrols for the latest conditions. Those statewide precautions line up closely with what Muskego police are now sounding the alarm about, according to the Wisconsin Department of Natural Resources.
Why shoreline ice fails first
Shoreline ice is usually the first to go. Shallow water warms up faster, sun and wind hammer the edges, and underwater springs keep water moving just below the surface, quietly thinning the ice from beneath. That kind of unpredictability has already had serious consequences on Pewaukee Lake. In January 2025, emergency crews responded to a fatal UTV plunge, later recovering the driver, a stark reminder of how quickly conditions can turn deadly. Local officials say ice that appears solid just a few yards away can be soft or rotten at the edges, a point reported by TMJ4.
How to stay safe
For those who still feel compelled to venture onto the ice, officials say the basics matter: tell someone your plans, carry a charged phone and a rope, wear a personal flotation device or float coat, and bring ice picks so you have a shot at self-rescue if you break through. Recovery of a vehicle that sinks is the owner’s responsibility and can quickly become expensive. Local and state officials warn that if a vehicle is not removed, the owner may face daily fines, according to the Wisconsin DNR. If you spot a person or vehicle in trouble, call 911, stay off the ice yourself and give dispatchers the most precise location you can.
