Fall trout and smallmouth window opens on Pittsburgh tailwaters
Gauge 03036000 reads 59°F at 210 cfs, 03039000 shows 60°F at 57.1 cfs, and 03039040 reports 63°F, all as of early Sunday morning. Those are comfortable temperatures for Rainbow Trout and Brown Trout, and cool enough that Smallmouth Bass should still feed with purpose through the middle of the day. Gauge 03036500 is running 6,340 cfs, a much larger flow than the smaller gauged reaches, so expect that stretch to fish very differently: heavier current, less visibility and fewer easy wading options. Per Tactical Bassin, jigs, soft jerkbaits and topwater are working around hard structure such as dock pilings, laid-down trees and rocks as fish settle into predictable fall positions. Fishing the Midwest adds that the bite can be hot as the weather cools. Both are general fall guidance rather than local reports, so treat them as a starting point.

Water in the high 50s to low 60s means fish stay active, and the low-flow readings at 03039000 and 03036000 favor careful presentations over heavy ones. Expect the best action in low light, with a second window once the sun warms the shallows in the afternoon.
The New Moon means dark nights and no strong moonlight pull, so dawn and dusk are the periods to plan around. For trout, MidCurrent's Tying Tuesday roundup points to beaded nymphs and spare midge-style patterns on overcast days and in clear, pressured water. For smallmouth, fall jig work along rock and wood is the pattern Tactical Bassin keeps returning to.
If you fish near the high-flow reach at 03036500, scale up weight and fish the softer edges and seams instead of the main push. Check conditions again before you go, since flows can change quickly after rain.
Context
Mid-October is typically a transition period for western Pennsylvania tailwaters. Summer warmth has faded, trout become more comfortable and active, and bass begin shifting toward predictable structure as baitfish move. Readings in the high 50s to low 60s are about what we would expect for this point in the season, so the pattern looks on schedule rather than early or late. Check Pennsylvania regulations and any stocking notices before keeping fish.
