Ice fishing shelters left unattended on land or water under the jurisdiction of the state must be labeled with the owner's name, street address, and city. Labels must be placed on all sides, and the lettering must be four-inch or larger block letters in a color contrasting to their background.

Reflectors must be attached to all sides on any shelter left on the ice after sundown.

Structures must not be locked while in use.

Shelters must be removed from all state-owned lands and waters by February 20 or ice melt, whichever comes first, unless the deadline is extended.
