Weekly AI Outlook as of 10/02/26
Early October on the Beaverkill is delivering classic fall conditions — clear, wade-able water below Roscoe after a modest rise, with foliage peaking and brown trout starting to think about spawning. Dette Flies confirms Black/Brown Stoneflies, black caddis, and small BWOs are on the surface, though nymphs and small streamers remain the most consistent producers. With highs in the upper 50s to mid-60s this week and a couple of light precip days, expect BWO windows to open midday — roughly 11am to 2pm — once air temps climb and light flattens. Trout Town Flies lists #18-20 BWOs, tan and cinnamon caddis, and Cahills/orange sulphurs as the October hatch menu. Fish nymphs and small streamers through the morning cold, then watch for rising fish near the Junction Pool C&R section as temps nudge toward 50°F. Egg patterns will grow more relevant as spawning activity picks up through the month.
- Conditions: Levels rose but remain clear and wade-able below Roscoe. Light precip on Oct 2 & 4 — watch for brief color, but nothing that should blow out access.
- Hatches: BWOs #18-20 midday, black caddis, tan/cinnamon caddis. Black/brown stonefly nymphs subsurface. Cahills and orange sulphurs possible mid-afternoon on warmer days.
- Water Temp: Seasonal range 48–54°F expected. Near or just below the 50°F caddis threshold — prime for BWOs and transitional streamer fishing near spawning lies.
- Best Window: 11am–2pm for surface BWO activity once air temps rise. Mornings favor tight-line nymphing or small streamers. Afternoons cool fast as lows drop to upper 30s by Sunday.

About this Water
- Freestone
- Best months: Apr–June & Sept–Oct, peak late Apr–May (Hendrickson)
The Beaverkill is hallowed American fly fishing ground — the 'mother of dry fly fishing' in the United States. Its Catskill pools and riffles gave rise to the Catskill style of fly tying and established the conventions of American trout fishing. The Beaverkill still holds wild brown trout in the public Catskill Center water, and fishing here carries an almost spiritual weight of history.
The Junction Pool, where the Willowemoc meets the Beaverkill, is one of the most photographed and storied pieces of trout water in America.
January Outlook
January on the Beaverkill is deep Catskill winter. This freestone river can freeze in cold years. The birthplace of American fly fishing sleeps under snow and ice. Plan the April Hendrickson trip.
