Fall smallmouth and walleye bite builds as Ohio waters cool
Water temperatures across southwest Ohio gauges ran from 55°F to 68°F on the evening of Oct. 22, a wide spread that shows how differently small streams and larger rivers are cooling. USGS gauge 03240000 read 55°F with flow near 41.5 cfs. USGS gauge 03274000 read 61°F at 1,610 cfs. USGS gauge 03242350 read 68°F. Fishing the Midwest's Mike Frisch calls October his favorite month on the water, citing lighter boat traffic and cooler water. Tactical Bassin's fall coverage describes bass schooling up and feeding on baitfish, with jerkbaits, swimbaits and underspins in play. Smallmouth Bass fit that pattern as the cold front-driven bite improves.

Expect the cooler gauges to keep sliding over the next few days, and the fish to follow. The 55°F reading at gauge 03240000 sits in the range where smallmouth typically slow their chase and favor slower, tighter presentations, while the 61°F to 68°F water at the other two gauges should still hold more active feeders. Plan around the warmest part of the afternoon on the cooler stretches, when a degree or two can switch fish on.
For walleye, Fishing the Midwest's Mike Frisch describes a plain snell rig on a bottom bouncer with a nightcrawler as a go-to in cooler water periods, which suits the pace this week calls for. Dawn and dusk are the windows worth planning around, with the waxing gibbous moon giving some evening light.
Flows look steady, with 1,610 cfs at gauge 03274000, so expect fishable clarity unless rain arrives. Check the forecast before heading out, since a sharp rise would push fish toward slack water and seams.
Context
Late October is typically the transition from the fall feeding peak to early winter patterns for Ohio freshwater. Baitfish move to the edges of dying weed beds and green cover, as Frisch describes in his fall coverage, and gamefish follow them. Smallmouth and walleye typically feed heavily ahead of winter, then settle into deeper, slower holding areas as water drops into the 40s. This year looks on schedule for the region, with river temperatures still above those of the coolest small streams.
