Ice is never 100% safe
The DNR does not measure ice thickness on Minnesota lakes. Your safety is your responsibility. Check ice thickness at least every 150 feet.
Keep it clean
It is unlawful to improperly dispose of garbage on the ice. Please clean up around your shack. What stays on the ice stays in the lake.
It is illegal to leave an ice fishing shack or pieces of it on the ice anywhere in Minnesota. Check with local refuse providers or landfills for ice shelter disposal information.
- All non-portable ice shelters must be licensed.
- Wheeled fish houses are not considered 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

- Owner's name and address
