Hosmer lake can fish the best of the cascade lakes in the fall. The streamer game can be rewarding and the fish are willing to eat bright streamers stripped fast. Bright and flashy crystal buggers can work. Small nymphs stripped slowly can work too. Pheasant tails and small callibaetis nymphs are good choices. The best of news is the dwindling crowds. Kayakers will still be present but not in the insane numbers of summer. Get out there and enjoy Hosmer while the weather is still great!
