Catskills and Adirondacks browns settle into a fall pattern
Late September marks the seasonal turn for Catskills and Adirondacks trout water: nights are cooling faster than days, pushing streams toward the fall pattern brown trout key on. Field & Stream's fall rig roundup this week backs a bottom-bouncing minnow rig on a barrel swivel as the standard for working big fall browns, keeping bait pinned in the strike zone as flows cool. A full moon overhead this week adds extra low-light feeding activity to work around at dawn and dusk.

Expect the cooling trend to continue through the weekend, nudging Catskills and Adirondacks streams further into the fall bite window. As water keeps easing down, look for brown trout to push more consistently into faster runs and undercut banks chasing baitfish, the exact water Field & Stream's bottom-bouncing minnow rig is built to cover.
With the full moon this week, dawn and dusk windows are worth prioritizing over midday, since low-light periods around a full moon typically pull more feeding activity toward the surface and away from deep cover. Weekend anglers should plan around first and last light rather than the middle of the day.
Context
Late September is squarely within the early fall transition for Adirondacks and Catskills trout streams, typically arriving on schedule as days shorten and nights drop into the 40s. This is normally when brown trout begin feeding harder ahead of the fall spawning run, a pattern consistent with the seasonal technique shift Field & Stream describes. Nothing about this year's timing reads as early or late relative to a typical late-September transition in this region.
