248-acre lake near Baraga County. The lake tops out around 35 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 rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 195 acres of water rimmed by 3.9 miles of bank. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. The shallow band under 15 ft claims about 64% of the surface — that's where the groceries are. Tip to tip the water measures near 1 mi with a 0.7-mi widest point. You'll find it in Baraga County. The nearest mapped water is Beaufort Lake, 2 mi to the southeast.
When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 15 to 35 ft, and by winter most fish are in 11 to 35 ft.

Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
