Finger Lakes smallmouth start eyeing the fall baitfish shift

What's biting

What's next

With water sitting at 65°F and flow already down to 14 cfs, expect the Finger Lakes to keep cooling gradually rather than crashing — a slow, steady slide is typical for mid-September and shouldn't scatter fish so much as start concentrating them. If the pattern documented by Fishing the Midwest holds (fish pulling off weed edges as shallower grass dies back and oxygen drops), anglers on Cayuga and Seneca should start working slightly deeper green weed lines over the next several days rather than the thinnest shallow growth that was productive in August.

Tactical Bassin's early-fall coverage describes bass sliding from structure-based summer patterns into open-water baitfish-following behavior, and that shift is one of the more reliable seasonal cues for smallmouth in lakes this size — worth watching for schools of bass suspended over deeper basins chasing baitfish balls, especially once mornings cool further. A bladed swim jig or similar reaction bait worked over deep weed edges (a combo Fishing the Midwest calls out as effective across bass, pike, and walleye) is a reasonable multi-species starting point if targeted intel is thin.

The new moon tonight typically sharpens low-light feeding windows — dawn and dusk sessions are worth prioritizing over the next few days over midday fishing, particularly for walleye and lake trout that tend to push shallower under darker skies. With low, stable flow at the gauge, water clarity should stay good, which favors finesse presentations and natural baitfish-imitating colors over bulkier, murky-water search baits.

No direct weekend-specific weather signal came through in this data pull, so treat timing windows as pattern-based rather than forecast-driven — check a local marine or lake forecast before locking in a weekend plan, particularly for wind direction on Cayuga and Seneca, both of which can build a chop quickly on their long north-south axes. If a cold front pushes through in the next week, expect an acceleration of the weed-edge and baitfish patterns described above rather than a reversal of them; a warming rebound would more likely stall the transition and keep fish shallower a bit longer.

Context

Mid-September water temperatures in the mid-60s are on-schedule for the Finger Lakes, which tend to hold summer stratification later into the season than shallower regional lakes because of their depth and volume — Seneca and Cayuga in particular are known for a slow, late cooldown compared to smaller waters. A 65°F reading and low baseflow at this point in September doesn't read as early or late; it tracks with a typical seasonal glide path toward the more pronounced fall turnover that usually shows up in October.

None of this cycle's angler-intel feeds carried a report specific to Cayuga, Seneca, or Skaneateles, so there's no direct comparative signal on how this season is running relative to prior years for these particular lakes — that's an honest gap rather than something we can paper over with general blog content. The available signal is limited to broader seasonal-pattern pieces from national outlets (Fishing the Midwest, Tactical Bassin) describing the general early-fall baitfish and weed-edge shift that shows up across northern multi-species lakes, which is consistent with, but not unique evidence about, what's happening on the Finger Lakes specifically this week. Anglers with recent on-the-water reports from these three lakes would meaningfully sharpen next week's update.
