Allegheny tailwaters ease into the early fall transition

What's next

Expect the next several days to keep nudging the water toward typical early-fall behavior: shortening daylight and cooler overnight air tend to firm up morning and evening feeding windows before the water itself has fully turned over. The waxing gibbous moon this week means brighter overnight sky, which can push some low-light activity slightly later into dusk and earlier into dawn than it would under a darker moon.

Weekend planning should lean toward the first and last light windows rather than midday, consistent with how this fishery typically behaves heading into October. Watch for the pattern to sharpen further as nights continue cooling through early October.

Context

For the Allegheny and Pittsburgh tailwaters, late September sits right at the front edge of the fall transition, on schedule rather than early or late. This is the stretch where the fishery typically pivots from summer thermal-refuge behavior toward the more active, feeding-driven pattern that builds through October as surface waters continue cooling. Nothing in current conditions suggests this year is running ahead of or behind that typical timeline.
