I rafted the Upper Yakima River from the mouth of the Teanaway River to the diversion dam at Thorp on Saturday. We casted red #1 Mepps spinners almost all day, with some occasional bronze ones thrown into the mix. The fishing was incredible, with the hits coming on nearly every cast over some stretches. We got a late start and were hustling to make the take-out for most of the day. Regardless we landed and released around a dozen small rainbows and I caught a cutthroat during a layover on shore while we snacked and rested. The large fish of the day was a 16″ rainbow that I hooked on the water and ran multiple times under my pontoon and back up the river.
