Catskills trout streams settle into low, cool fall water

What's biting

What's next

Low, clear water means fish are spooky in the thin runs and will hold in deeper pools and seams. Expect the best action in the cooler, lower-light hours: early morning and the last hour before dark. A new moon means dark nights, and dim conditions can encourage bolder daytime movement from larger fish.

If temperatures keep sliding toward the low 50s, streamer fishing should keep improving. Flylords Mag suggests drifting streamers in early autumn, which suits these low flows well, since a slow dead-drift through a deep pool can draw strikes from fish that ignore a stripped fly. Per Gink and Gasoline, nymph rigs often fail simply for lack of weight, so add split shot until the flies are ticking bottom. Caddis Fly (OR) lists the Perdigon as a hot fly this fall, and a slim, heavy pattern like it sinks quickly in the lower-volume runs here.

At this flow, stay back from the water and keep a low profile. Longer leaders and fine tippet help in the clear, skinny stretches.

Context

Mid-October in the Catskills and Adirondacks sits squarely in the fall phase. Terrestrials have faded and insect hatches are thinner, so trout key on small mayflies and midges, plus baitfish and eggs. Brown Trout and Brook Trout are typically near spawning, which tends to make them aggressive and also puts redds on gravel in the tails of pools. Wade carefully and avoid stepping on those areas. Check current state regulations for any seasonal closures or special-regulation sections before heading out.
