Susquehanna trout and smallmouth ease into fall patterns

What's biting

What's next

Expect the New Moon to bring dark nights and little light pressure, so the first and last hour of daylight are the windows to plan around. Smaller water at 186 cfs should stay clear and low, which favors light tippets and quiet approaches for trout. The larger flow at 5,290 cfs will push fish toward softer seams and eddies out of the main current, so work the edges rather than the middle.

As nights lengthen, water at the cooler gauges should drift down through the 50s. That typically turns on a more aggressive streamer and jig bite for Smallmouth Bass in the afternoon warmth, while Brown Trout and Rainbow Trout stay active in the cooler morning hours. Tactical Bassin (blog) notes fall bass hold near hard structure such as dock pilings, laydowns and rocks, a good template for any slow, deep pool. Midcurrent's recent Tying Tuesday features point to attractor and midge patterns that suit low, clear water. Check the PA Fish & Boat Commission biologist reports page and state regulations before harvesting any trout.

Context

Mid October is the heart of fall in central Pennsylvania. Smallmouth typically begin moving off summer haunts toward deeper, slower water as temperatures slide, but they remain catchable on jigs and slow presentations until the water drops well into the 40s. Trout streams typically see more comfortable temperatures and better oxygen now than in August, and stocked and wild fish alike tend to feed more freely. This season looks on schedule, with flows near typical autumn levels on the smaller waters and moderate on the larger river.
