Allegheny Fishing Forecast
The Allegheny in Pennsylvania behaves like a classic tailwater: cold, predictable releases that stretch the trout season when freestone neighbors run warm or muddy. Anglers target brook trout, brown trout, and rainbow trout across riffles, seams, and undercut banks in the Eastern US, with prime dry-fly and nymph windows typically clustering in April through October. USGS gauge 03012500 tracks live flow and temperature for planning wade or float days. Local tactics angle: The Allegheny River below Kinzua Dam offers excellent fishing for rainbow and brown trout in a tailwater setting, plus quality smallmouth bass fishing below. TroutFishing pairs hatch timing with solunar windows so you know when to be on the water—not just where.
The Allegheny tailwater is sitting at moderate flows with a stable 43°F°F reading. Today's rating: 5/10. Top pick: a WD-40.
