The Yakima has been fishing well, with pretty much the same flies/techniques working as mentioned in the previous report.
Our guide staff has been fishing throughout the system, and we've noticed that water temps are reaching lethal levels for trout (68-70 degrees) in the afternoon/evening hours in the lower canyon. We recommend leaving this stretch of river for morning floats only, and not fishing past 12pm. This will give you, the angler, your best shot at actively feeding fish, and will give the fish a much needed break when water temperatures climb.
Water temperatures in the upper river have been significantly cooler throughout the day, with temps in the low to mid-60s, which is still in the safe zone. If you are planning on floating or fishing during the evening hours, the stretch of river from the diversion dam upstream will be your best bet with cooler water and happy fish. And yes, the fishing has been pretty damn good up there as well!
