Coho,
I also had this question myself so I called the WDFW at Montesano and they said that because there was a Non Bouyant Lure Restriction as well a Single Barbless Hooks
restriction (emphasis on Hooks plural),that you could rig floating lures with up to three single point barbless hooks.

This applies to rivers such as the Satsop and Hump.The Three Rivers and the Hoh you can pretty much do whatever.

These rules however, seem to be subject to the mood of the game agent's interpretation
at the time he is checking you.GO MARINERS
