All trout harvested must be caught on artificial lures. In this area only, artificial lures cannot contain or have attached either whole or portions, living or dead, of organisms such as fish, crayfish, insects or worms, any other animal or vegetable material, or synthetic scented materials. This does not prohibit the use of artificial lures that contain components of hair or feathers.
