31-acre lake near Otter Tail County. The lake tops out around 12 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. The season-by-season read for each species follows, from the map's own numbers.
Unnamed Lake (Otter Tail County) maps at 31 acres behind 2.2 miles of shoreline. That shoreline is heavily fingered (development index 2.8) — bays, points and pockets everywhere, which multiplies the fishable edge. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Tip to tip the water measures near 0.7 mi with a 0.2-mi widest point. Otter Tail County claims this one. Prairie sits 2 mi north — the closest neighbouring chart.
In spring, walleye run shallow here, mostly 3 to 12 ft. Summer keeps them at 4 to 12 ft, and they winter in 4 to 12 ft. Deep basin is the standout, a deep basin at roughly 12 ft, rated prime for winter walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.

A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
