Artificial Fly A fly is a hook, dressed with conventional fly tying materials. The affixed materials may be natural or synthetic.
Tied in conjunction with other materials, the following items may be part of the fly: wire (lead or other metal) used
for weighting the fly, dumbbell eyes or beads (metal, glass or plastic).
A fly is not a hook to which sinkers, molded
weights, spinners, spoons or similar attractors are attached.
Fly Angling Angling with a fly rod, fly reel, (no spinning or fixed spool reel(s)), floating or sinking fly line, leader, any type of
backing line, and an artificial fly.
In waters restricted to “Fly Angling Only” no additional weights or attractors shall
be attached to the hook, leader, or line, and no metal core lines may be used.
Lure An artificial device, complete with hooks, intended to attract and entice fish; excluding molded soft plastic or
rubber imitation baits and artificial flies. Corkies, spin-n-glos, go-glos, birdy drifters,
lead-head jigs, etc., are considered
lures. Molded soft plastic or rubber imitation worms, eggs, or other imitation baits are considered bait.
