Ice fish house regulations, etiquette and safety tips
by Rich Mickschl
Winter has officially arrived, and ice fishing is now in full swing on Lake Independence! After last year, we know many are eager to get back out on the ice and enjoy the season. With that in mind, we thought this would be a great time to review a few important regulations, etiquette reminders, and safety tips to ensure everyone has a safe and enjoyable experience.
Minnesota DNR Ice Fish House Regulations
-
All non-portable ice shelters must be licensed.
-
Wheeled fish houses are considered non-portable and must be licensed.
-
An annual shelter license costs $15 for residents and $37 for non-residents, not including issuing fees that may be charged.
-
The ice shelter license must be readily visible from the exterior of the shelter.
-
A shelter license is valid from March 1 through April 30 of the following year.
-
A shelter license is not required on border waters between Minnesota or Wisconsin, Iowa and North and South Dakota.
Portable shelter definition: a shelter that collapses, folds or is disassembled for transportation. Portable shelters only need licenses and identification when left unattended, which is defined as all occupants being more than 200 feet away.
​
Shelter identification requirements:
-
ONE of the following must be readily visible from the exterior of the shelter with characters at least 2 inches high:
-
Owner's name and address
-
Owner's driver’s license number
-
Owner's Minnesota DNR identification number.
-
-
If a shelter is left out overnight, it must have at least 2 square inches of reflective material on each side.
New litter law in effect:
It is unlawful to improperly dispose of garbage, sewage or wastewater on the ice.
New in 2023 is a requirement that anyone using a shelter, motor vehicle or other conveyance on the ice may not deposit trash or waste outside unless the material is:
-
In a container that’s secured to the shelter, motor vehicle or conveyance, and
-
Not placed directly on the ice or in state waters
Shelter removal deadlines:
Dark houses, fish houses and portables must be off the ice no later than 11:59 p.m. (end of the day) on March 3, 2025 for Hennepin County lakes. County sheriffs may prohibit or restrict the use of motorized vehicles if dangerous ice conditions are present. If shelters are not removed, owners may be cited. A conservation officer also may confiscate, remove or destroy any ice structure and its contents if not removed by the deadline.
​
Ice Fishing Etiquette:
-
Don’t fish out of other people’s holes that they drilled. Ask for permission.
-
Don’t drill holes by other people’s tip-ups or Ice Fish House.
-
Keep a respectful distance from other people’s holes and Ice Fish House.
-
Pick up your trash before you leave.
-
Mark Larger cut holes.
-
Don’t assume you can borrow gear.
-
Be quiet, others are trying to enjoy their time too.
-
Don’t drill holes on Plowed Roads.
-
Do not speed on plowed roads, 15 mph.
-
Do not come on the ice without a restroom plan ​
Ice thickness guidelines for new, clear ice only.
Under 4” Stay off Ice
4” Ice fishing or other activities by foot
5-7” Snowmobile or small ATV
7-8” side by side ATV
9-10” Small Car or SUV
11-12” Medium SUV or Small Truck
13” Medium Truck
16-17” Heavy Duty Truck
20+ Heavy Duty Truck with Wheelhouse Shelter
Many factors other than thickness affect ice strength, including air temperature, wind, snow, streams, narrow areas or bottlenecks, sun, shade, fish communities, plant decay, and more. When a layer of snow melts and refreezes on top of lake ice, it creates white ice, only about half as strong as new, clear ice. Double the above thickness guidelines when traveling on white ice.

Ice Safety Tips
Must-Have Ice Fishing Safety Gear
Ice Picks/Rescue Picks:
Ice picks are a lifesaving tool if you fall through the ice. These sharp tools allow you to pull yourself back onto solid ice.
How to Use:
-
Keep the picks around your neck or in a place for easy access.
-
After falling through, use them to drive into the ice and pull yourself out while kicking your legs.
​
Ice Chisel (Spud Bar):
An ice chisel helps check ice thickness as you walk, ensuring the ice can support your weight.
How to Use:
-
Strike the ice in front of you and observe how easily it breaks. If the chisel goes through with just a few strikes, it’s too thin for walking.

What should you do if you fall through the ice?
(Created by the Minnesota DNR and KARE11)
First, try not to panic. This may be easier said than done, unless you have worked out a survival plan in advance. Read through these steps so that you can be prepared.
-
Don't remove your winter clothing. Heavy clothes won't drag you down, but instead can trap air to provide warmth and flotation. This is especially true with a snowmobile suit.
-
Turn toward the direction you came. That’s probably the strongest ice.
-
Place your hands and arms on the unbroken surface. This is where a pair of nails, sharpened screwdrivers or ice picks comes in handy in providing the extra traction you need to pull yourself up onto the ice.
-
Kick your feet and dig in your ice picks to work your way back onto the solid ice. If your clothes have trapped a lot of water, you may have to lift yourself partially out of the water on your elbows to let the water drain before starting forward.
-
Lie flat on the ice once you are out and roll away from the hole to keep your weight spread out. This may help prevent you from breaking through again.
-
Get to a warm, dry, sheltered area and re-warm yourself immediately. In moderate to severe cases of cold water hypothermia, you must seek medical attention. Cold blood trapped in your extremities can come rushing back to your heart after you begin to re-warm. The shock of the chilled blood may cause ventricular fibrillation leading to a heart attack and death! ​
Remember that Ice is never 100% safe
The recent cold temperatures have significantly improved ice conditions on Lake Independence, creating a solid layer for winter activities. However, please remember that ice is never 100% safe. Make sure you understand ice safety before venturing out, and check out the ice safety information available here on our homepage for important guidelines. Stay safe and enjoy the season!
-
Check ice conditions with a local bait shop or call Hennepin County Water Patrol
at 612-596-9880. -
Never consider ice completely safe. Never go onto ice alone. Carry a set of ice
rescue claws. -
Let someone know where you’ll be and when you plan to go home.
-
Only walk on ice that is at least 4 inches thick.
-
For skating, physically check the ice with a chisel or drill. Ice changes even within a few feet.
-
If you break through the ice, don’t panic. Turn around and get out the same direction you came from. Call 911 and seek warm dry shelter.
-
Avoid any place where water is moving under the ice.
-
Follow the same rules for life jackets as on open water.
Mercury Levels High Mercury Levels in Fish Linked to Zebra Mussel Infestations in Minnesota Lakes
Minnesota is grappling with a troubling environmental issue: the rise of mercury levels in fish from lakes infested with zebra mussels. This invasive species, originally from Eurasia, has spread rapidly across North America, significantly altering aquatic ecosystems. Recent studies suggest a disturbing connection between zebra mussel infestations and elevated mercury concentrations in fish, posing risks to human health and the environment.
Zebra Mussels and Their Impact on Ecosystems
Zebra mussels (Dreissena polymorpha) were first discovered in Minnesota in the late 1980s and have since invaded many lakes and rivers. These small, filter-feeding mollusks are notorious for their ability to outcompete native species and disrupt food chains. They filter vast amounts of water, removing plankton and other particles, which has cascading effects on aquatic ecosystems.
By filtering water so effectively, zebra mussels increase water clarity, allowing sunlight to penetrate deeper. This promotes the growth of aquatic plants and algae, which can lead to oxygen depletion and changes in fish habitats. However, their impact goes beyond these visible changes; they also play a role in altering mercury dynamics in lakes.
Mercury in Lakes: A Persistent Threat
Mercury is a toxic element that accumulates in aquatic systems primarily through atmospheric deposition. Once in the water, mercury can be transformed by bacteria into methylmercury, a highly toxic form that bioaccumulates in the food chain. Fish at the top of the food web, such as walleye and northern pike, often have the highest mercury levels.
Studies have shown that zebra mussels can influence mercury cycling in lakes. By altering the food web and increasing algal blooms, they create conditions that may enhance the production and accumulation of methylmercury. Additionally, zebra mussels themselves can concentrate mercury, which then becomes available to other organisms through predation.
Evidence from Minnesota Lakes
Recent research conducted in Minnesota has revealed a concerning trend: lakes with zebra mussel infestations often have fish with higher mercury levels compared to non-infested lakes. For example, in some infested lakes, mercury concentrations in popular game fish have exceeded safe consumption limits set by the Minnesota Department of Health. This has raised alarms among anglers and public health officials alike.
The relationship between zebra mussels and mercury levels is complex and influenced by various factors, including lake size, water chemistry, and the extent of infestation. However, the evidence suggests that zebra mussels exacerbate the problem of mercury contamination in fish, adding another layer of concern to their ecological impact.
Implications for Public Health and Policy
High mercury levels in fish pose significant risks to human health, particularly for pregnant women, nursing mothers, and young children. Consuming fish with elevated mercury can impair neurological development and lead to other health issues.
To address this issue, Minnesota officials are ramping up efforts to prevent the spread of zebra mussels and monitor mercury levels in fish. Anglers are urged to follow fish consumption advisories and report any sightings of zebra mussels in uninfested lakes.
Moving Forward
The link between zebra mussels and mercury contamination underscores the need for comprehensive management strategies to protect Minnesota's lakes. Public education, stricter regulations on boat cleaning, and continued research into the ecological impacts of zebra mussels are critical.
As Minnesotans enjoy their lakes, they must remain vigilant in safeguarding these natural treasures. Tackling the dual threats of invasive species and mercury contamination will require collaboration among scientists, policymakers, and communities to ensure the health of both the lakes and the people who rely on them.
