838-acre lake near Alger County. The lake tops out around 30 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. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 869 acres, worked by 5.9 miles of shoreline. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 72% of this chart. Tip to tip the water measures near 2 mi with a 1.2-mi widest point. Alger County claims this one. Its nearest charted neighbour, Perch Lake, is 6 mi to the east.
The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 9 to 30 ft, wintering in 9 to 30 ft. Top water on the chart: Break off the point, a drop-off in the 19 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
