Fall walleye and smallmouth shift as Wabash cools toward turnover

What's biting

What's next

Expect water temperatures to keep sliding if nights stay cool, and the 60°F reading at gauge 395223086214202 shows how quickly smaller, shallower water drops. As temperatures fall through the low 60s, walleyes and smallmouth typically push toward deeper structure and feed harder on baitfish. Per Tactical Bassin, bass chasing baitfish in the fall respond well to a swimbait with an added blade, such as an underspin, for flash and vibration. The same source highlights shallow jigs, soft jerkbaits and topwater for October bass when fish hold on subtle shallow spots.

Plan the best windows around the warmest part of the afternoon on cold-front days, and early and late on stable, overcast days. Field & Stream notes that fall turnover does not hit a fishery all at once, so shallow bays and creek arms may flip first. Avoid off-color, debris-filled water and look for clear water, using search baits like spinnerbaits to locate active fish. Gauge 03335500 is running 3,980 cfs, a much higher flow than the other sites, so expect some current there and check conditions before wading or launching.

Context

Mid-October typically marks the heart of fall patterns across Indiana rivers and Lake Michigan: summer weed growth is dying back, baitfish relocate, and gamefish follow. Per Fishing the Midwest, fish often congregate around the green weeds that remain, since dying weeds deplete oxygen and thin out cover. That makes this a transition period, with temperatures right where they usually sit for the season.
