Minnesota Lake Ice In Dates

 

Please note: lake ice-in dates for the current year will not be posted in real time due to safety concerns, and because the ice cover may not be permanent for the season.

The DNR does not measure ice thickness on Minnesota lakes. Your safety is your responsibility. Check ice thickness as you go.

Ice is never 100% safe!

Ice in dates should not be used to track ice thickness for recreational use. Ice conditions can change rapidly and should be checked frequently. Review ice safety tips.

Definition of lake ice in

The definition of lake ice in can vary from lake to lake. For the citizen observers reporting data, ice in occurs when the entire lake is frozen over and the ice cover remains through winter. Observers do not report ice thickness.
