Fall turnover sets up walleye and smallmouth on the Upper Mississippi
The Upper Mississippi pools between Prescott and La Crosse are deep into the fall turnover window, and regional technique reports back it up. Fishing the Midwest's Mike Frisch points to a simple bottom-bouncer-and-nightcrawler setup, the "plain rig," as a proven producer once walleyes shift out of summer structure and into the cooler water periods of fall. Field & Stream's fall smallmouth bass guidance lines up with the same shift: target current and wind-blown banks where baitfish are stacking, working crankbaits and jerkbaits to cover water before slowing down once fish group up. No validated water temperature or flow readings are in from local gauges this week, but the seasonal cues these sources describe match where this stretch of river sits on the calendar.

Expect the walleye bite to keep strengthening as water continues cooling through the week. Frisch's plain rig should stay relevant moving from main-channel structure into the slower eddies and wing-dam pools typical of these pools as fall deepens. For smallmouth, keep working the wind-exposed banks and current seams Field & Stream flags, since baitfish schools pushed by wind will keep concentrating fish in predictable spots.
The Last Quarter moon favors shorter feeding windows around dawn and dusk rather than steady activity through the day, so plan trips around those low-light periods. With no tide or flow data in from gauges on this stretch yet, check current river stage and clarity locally before committing to a stretch, especially after any rain this week.
Context
This timing is right on schedule for the Upper Mississippi pools: early October is the heart of the fall transition, when walleyes abandon summer haunts for transitional structure and smallmouth bass group tightly around remaining baitfish concentrations before the water cools further toward winter positioning. Weed die-off typical of this period pushes baitfish, and the gamefish that follow them, onto cleaner structure, a pattern consistent with what regional sources are describing right now.
