You can use a third line if you have a valid third line fishing permit. You cannot leave fishing line or lines with hooks in the water unattended by being out of visual sight of the lines. One hook is a single, double or treble-pointed hook, and all hooks attached as a part of an artificial bait or lure are counted as one hook. An Alabama (umbrella) rig is not an artificial bait or lure. Ice Fishing Shelters: Ice fishing shelters left unattended on land or water under the jurisdiction of the state, must have the owner's name, street address and city in 4-inch or larger block letters (in a color contrasting to their background) on all sides, but do not need to be registered. Attach reflectors to all sides of any shelter left on the ice after sundown. Keep shelters unlocked while in use. Remove shelters from all state-owned lands and waters by Feb. 20 or ice melt, whichever comes first, unless the deadline is extended. Tip-Up Fishing Device: A "tip-up" is an ice fishing device with an attached flag or signal to show fishing action, used to hold fishing line and a hook. You may fish a combination of one tip-up and one additional line, or two tip-ups and no additional lines. You can use an additional line or tip-up if you have a third line fishing permit. When fishing the Mississippi, Missouri and Big Sioux Rivers and their connected backwaters, the following regulations apply: you can use up to three tip-up fishing devices. You can use two or three hooks on the same line, but the total number of hooks each person uses cannot exceed three. Each tip-up fishing device must have a tag attached, plainly labeled with the owner's name and address.
