Hooks, Lures and Tackle Configurations
Single Tackle Configuration. Anglers may use up to three single or multiplepronged
(example – treble) hooks on a line used as a single tackle configuration
attached to the end of a fishing line (Examples – crawler harness, quick-strike
rig. See pictures on page 63). Note: a single tackle configuration cannot be
used on designated trout streams and lakes.
– The total length of the single tackle configuration from the first hook to the
last hook must be nine inches or less.
– Anglers may use live, artificial, preserved, or dead bait that is lawful to use
(see page 12).
– This single tackle configuration is not considered an artificial fly or lure/
bait, and no additional hooks may be used. Adding a bead, blade, or
spinner does not make it into an artificial lure/bait.
The Picture shows 3 Treble hooks – Not Lures. I’m not totally sure of the intent of this rule – Looks like another Grey area to me.
