The water temps are 61 degrees, so the fish are active. Terrestrial and stone fly patterns have been the ticket throughout the day and caddis in the evening. For dries; a brown, tan, or olive simulator size 8-12 with rubber legs; chernobyls in red, tan, and brown, size 6-12; hopper size 6-10, and PMX's in olive, green, red, and orange, size 8-12. Dry-dropper combos have been doing well too. Nymphs that are working are stones, PT's, Copper Johns, and San Juan Worms. The fish have been stacked up on the edge of the banks because of the normally high summer flows, so wading is difficult right now. The optimal way to fish the Yakima River right now is from a drift boat or raft and putting your flies withing five inches of the bank. The catching has been good, usually in the double digits.
