Fly fishing klg is tough because most of the fish in there have been hooked several times and see the same flies everyday. They are very smart! If you want to catch fish there I suggest 7x flourocarbon tippet and do not use any nymph larger than a size 18. I use 3 flies when I nymph, a hares ear wet up top, pheasant tail in the middle, and maybe a beadhead prince on the bottom with no weight at all. Use a small pinch on strike indicator as well so you don't spook the fish when roll casting. Also, it may be tempting to fish the slower pools since you can see the fish. Those fish run on batteries, they will only look at your flies this late in the season. Stick to the moving water and big rocks, there is usually a hungry trout behind each one.
