While it may not feel like it today, winter is transitioning toward spring, and state officials are reminding ice anglers of upcoming deadlines to remove shelters from northern Minnesota and U.S./Canadian border waters.
For those fishing in the northern third of Minnesota, the deadline to remove ice shelters from inland waters is 11:59 p.m. on March 16, 2026. The line is set by an east-west line formed by U.S. Hwy. 10, east along Hwy. 34 to Minnesota Hwy. 200, east along Hwy. 200 to U.S. Hwy. 2, and east along Hwy. 2 to the Minnesota-Wisconsin border, according to the DNR. For waters along the Canada-U.S. border, the deadline is March 31.

According to a news release from the Minnesota Department of Natural Resources (DNR), these deadlines are firm, though shelters may be used after these dates between sunrise and sunset if ice conditions remain safe. Additionally, "shelters may remain on the ice between midnight and one hour before sunrise only when occupied or attended." If a shelter is not removed by the deadline, owners may face citations, and local authorities may remove and confiscate the structure.
Beyond the requirement to remove shelters, officials are reminding anglers to remove trash that is often left behind on the ice. According to a recent release from the Minnesota Pollution Control Agency (MPCA), efforts to reduce "ice garbage" have shown progress, but litter remains a persistent issue. Common items left behind include cigarette butts, beverage containers, and plastic waste, which sink to the lake bed once the ice melts.
To combat this, a Minnesota law that took effect in 2023 specifically targets the disposal of waste in frozen waters. The legislation "addresses one of the most commonly received complaints in winter to conservation officers." Under the law, it is illegal to leave any "garbage, burning charcoal, or other debris" on the ice. Anglers are required to have a container for waste—such as a trash bag or bucket—attached to their shelter or nearby while fishing.
The DNR also reminds the public that ice conditions can change rapidly during the "ice out" period. Even if a removal deadline has not yet passed, unseasonably warm weather can make the ice unstable for vehicles or heavy equipment used to haul shelters. Anglers are encouraged to check ice thickness frequently and "not to rely on any specific date" as a guarantee of safety.
The MN Ice Thaw Tracker
As we move further into spring, many may be wondering when "ice out" will occur on area lakes. To help track this data, the Minnesota Sea Grant launched the "MN Ice Thaw Tracker" in 2025. This tool, often referred to as a "thaw clock," was developed to provide more precise predictions for when Minnesota lakes will become available for recreational use. According to Minnesota Sea Grant, the tracker is intended to serve outdoor enthusiasts and the tourism industry by forecasting when bodies of water will be clear for boating and recreation.
The system uses satellite data and community observations to generate forecasts. However, while the tracker offers forecasts for many regions, data gaps can hinder accuracy in rural areas. Many smaller or more remote lakes in northern Minnesota lack the consistent historical data and frequent ground-level reporting necessary to calibrate the models effectively.
As a workaround, the MN Sea Grant suggests looking across counties, such as Lake or St. Louis Counties, "for lakes at about the same latitude and the same size, and follow their forecasts," while also factoring in that "they will also be a bit later than forecast, too, because they are pulling data from Hibbing or International Falls." This can give the user a general idea of lake conditions in places where data isn't readily available.
Because of these limitations, officials and researchers stress the need for manual checks by local residents, which remain essential for ensuring safety during the thaw.
