Ice fishing shelters may be placed on or over state owned land or waters. The full name, street address and city of the structure owner must be painted in a contrasting color on all sides of the shelter in block letters at least four inches high. Shelters on the ice after sunset are required to have reflectors attached to all sides. All shelters must be removed from the ice on or before ice melt or February 20 of each year, whichever comes first.
