Little olives and isos will be staples, but some sulphurs and cahills may be about. Ants and beetles still work.
Two theories on nymphs. 1. It's low and clear and there are plenty of bwos about so small pheasant tails are the ticket. Have had good luck with small Prince nymphs for fish nymphing during the bwo hatch too.
2. Fish are putting on the feedbag for winter and will go for a big meal. Size 12 to 14 pheasant tails with ice dub thorax and rubber legs or Prince nymphs. Stoneflies too. I like Prince nymphs in the fast water because the bows are starting to head up the E Branch to the Beaverkill and Willow. other big uglies work well at times.
