WDFW recently posted up some new rule changes, find them here.
As of May 1st, 2013 barbed hooks cannot be used on the Klickitat. Trebles, etc. are ok but they must be de-barbed. Pinching the barb with a pliers will take care of the issue. I think it’s a good rule change, keep a tight line and you’ll still land the fish…maybe bow to a jumper… All-in-all, more interesting I think.
