According to NR 20.03(40) of the Wisconsin Administrative Code, "troll" or "trolling" means fishing by trailing any lure, bait or similar device that may be used to attract or catch fish from a boat propelled by a means other than drifting, pedaling, paddling, or rowing. Casting and immediate retrieval of bait, lure, or similar device while the motor is running (or “position fishing”) are not considered trolling.

Frequently asked trolling questions
I routinely fish a lake that crosses county boundaries (One county has a maximum of 3 lines per boat and the other county has no maximum of the lines trolled per boat). How is that situation regulated?
Because these are county-by-county rules, they will be enforced by the county line. Rather than having to list exceptions for every water that crosses a county line, the rules follow the county lines. In this particular case, a maximum of 3 lines per boat anywhere on the lake will keep you clearly within the law, but you could use 3 lines/angler where you cross the county line into the less restrictive portion of the lake. When the rules between counties differ, you should follow the rules of the county in which you are fishing.
Does the trolling rule override ordinances prohibit the use of motorboats?
This change does not affect boating regulations, so anglers must still comply with any motor restrictions applicable on the lakes. As before, a person holding a valid disabled permit that authorizes trolling (trolling, Class A, Class B with trolling) would be authorized to use an electric motor on lakes with ordinances enacted that prohibit the use of motorboats on navigable waters.
If I am fishing on a water where I can only use 1 “line” to troll and up to two lines per boat, can I cast with another line?
Yes, the trolling line restriction only applies to the number of lines being trolled. Any person can fish statewide with up to three hooks, baits, or lures at a time. If you are trolling with one line that has one lure attached, you can cast at the same time with another lure. The same goes for boats – if two people are each trolling a line from a boat, they are still allowed to use additional non-trolling lines up to their maximum of three hooks, baits, or lures per person.
