Life stage + What’s on the menu
Primary species: Walleye
Bass life stage (late Sep ND — seasonal): Fall transition / pre-turnover window depending on lake depth. Cooler nights push bait shallow-to-mid; largemouth and smallmouth (where present) key on bait schools and wind-blown banks. Deep mainstem reservoirs: focus points, flooded timber edges, and current seams near structure.
What’s on the menu: Most likely young-of-year baitfish / cisco-smelt-shad analogs by water, perch/bluegill where present. Thin on dated 2026 forage reports this pass — seasonal most-likely only.
Also on this water
Walleye; northern pike; yellow perch; crappie.
