Fall cooldown sets up Ohio smallmouth and walleye windows
Gauge readings across southwest Ohio show water in the mid 50s to upper 60s this evening. USGS gauge 03240000 reads 55°F with flow near 54 cfs, gauge 03274000 reads 61°F at 1,750 cfs, and gauge 03242350 reads 68°F. That spread matters: the cooler, steadier water is where fall fish start to feed with purpose. Tactical Bassin (blog) notes that bass chasing baitfish in the fall respond to a swimbait on an underspin, since the added flash and vibration draws strikes. Fishing the Midwest says October is its favorite month on the water, with boat traffic gone and the bite improving as the weather cools.

Expect the warmer stretches, like the 68°F reading, to keep sliding toward the low 60s as nights lengthen. As that happens, smallmouth should push toward baitfish concentrations and stay more predictable through midday.
For walleye, Fishing the Midwest describes a plain rig, a bottom bouncer with a snell and nightcrawler, as a dependable choice in cooler fall water. Plan the first and last two hours of light for that approach.
The moon is waxing gibbous and building toward full this week. Low-light and overnight windows around the brighter moon are worth planning for walleye. Stable flow at the smaller gauge suggests clear, fishable water. Where flow is higher, work eddies and slack edges rather than the main current.
Context
Late October is typically the peak of the fall transition on Ohio rivers and reservoirs. Fish shift from summer patterns to feeding up ahead of winter. Fishing the Midwest points out that weeds die back as waters cool, so fish relocate to the green weeds that remain. Finding that live vegetation is often a good starting point. Smallmouth and walleye typically hold near current breaks and baitfish, and crappie and bluegill tend to tighten up around cover as temperatures drop. Check state regulations before harvesting.
