Prime feeding temps — weed edges, points, and wind-blown shorelines.

A walleye-depth rule of thumb from the water temp — light, wind, clarity, and baitfish all move them, and it reads open water so warm bays fish shallower. Suggested, not a guarantee.

An open-water surface estimate from recent air temperature and sunshine — there’s no live water-temperature sensor on this lake yet. Sheltered bays (like Grassy Portage) run warmer, and deep water colder.

Adjusted -1.8°F from 5 angler reports.

Water leaving the lake down the Rainy River (dam-regulated at International Falls) — a rough gauge of how much current is moving through the system, and the “normal” line compares today with the USGS record for this date. As a rule of thumb many anglers work current seams and pinch points harder when flow is up; treat it as a hint, not a guarantee.
