Catskill trout streams settle into low, clear fall water

What's biting

What's next

Expect the same low, clear pattern to hold through the next few days unless rain arrives, so plan around the cooler hours. With 51°F water on the colder gauge, trout should feed best from mid-morning through the afternoon, when the water warms a few degrees and any remaining hatches show.

Per Field & Stream, low, clear autumn water calls for long leaders, 12 feet or more, tapered to 6X or 7X, with small parachutes or Compara-duns. They name blue-winged olives as the dominant fall mayfly hatch. If weather turns, they suggest shifting to nymphs or big orange caddis patterns.

Flylords Mag suggests drifting streamers in early autumn rather than only stripping them. On the larger flows near 122 cfs, that approach gives trout a longer look at the fly. On the smallest streams, approach low and slow, since fish there have little cover.

The waxing crescent moon sets early, so evenings are dark. Daylight is the best window, and you should check conditions before heading out, since small streams can change quickly after rain.

Context

Mid-October is the back half of the fall season on Catskill and Adirondack trout water, and this week looks on schedule. Cooling nights have pulled temperatures into the low 50s on the colder gauge, a range where trout feed steadily and pre-spawn Brown Trout become more aggressive toward streamers. Insect activity thins as the month goes on, which is why anglers typically shift from dry flies toward nymphs and baitfish patterns. Low autumn flows are common, and they concentrate fish in deeper runs and pools. Check state regulations for any seasonal closures or catch-and-release rules on spawning water.
