Fall walleye and smallmouth window opens on cooling Indiana water
Water is cooling into the fall feeding range. USGS gauge 03353200 reads 57°F and gauge 05524500 reads 55°F, while gauge 395223086214202 shows 60°F. That spread puts rivers in the mid-to-upper 50s, the band where predatory fish turn aggressive ahead of winter. Fishing the Midwest calls October its favorite month, with fewer boats and a strong bite, and Mike Frisch describes a plain snell and nightcrawler on a bottom bouncer as a go-to for fall walleyes. Tactical Bassin says bass are schooling and chasing baitfish this fall, so smallmouth should be feeding on the move.

Expect water temperatures to keep sliding a degree or two over the next few days if nights stay cool. That should pull baitfish toward deeper, slower water and bring walleyes and smallmouth with them.
Tactical Bassin points to jerkbaits and bladed swimbaits or underspins as fall producers when bass are chasing shad. Match that to current: gauge 03335500 is moving 2,410 cfs, a strong flow, so look for eddies and slack water beside the main push. Gauge 03353200 at 10.6 cfs and gauge 05524500 at 94.4 cfs are gentle by comparison, so those smaller flows should fish cleanly and stay clearer.
Plan on low light. Early morning and the last hour of daylight typically give the best walleye and smallmouth activity in cooling water. With a waxing gibbous moon, evening hours are lit well, so dusk sessions into the night are worth considering for walleyes. Check state regs before harvesting.
Context
Late October is the cool-water transition for Indiana rivers and southern Lake Michigan, and mid-50s readings are on schedule for the season. Fish are bulking up before winter, and fall is typically one of the more productive stretches of the year. Crowds thin out as boaters and hunters leave the water, which suits anglers who want the places to themselves.
