Though your annual fishing license allows you to fish  statewide, Wyoming is divided into five drainage areas, and the rules for live baitfish are different in each area. The rules include where you can use live baitfish, what types, and their origin. To ensure that you can use live baitfish for fishing in the water you are planning to visit, consult the Wyoming Fishing Regulations, Live Baitfish sections. Also note, rules on the same water (such as the North Platte) can vary depending where you are. Taking close note of these regulations should help you have an enjoyable fishing trip.
