27-acre lake near Gogebic County. The lake tops out around 20 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 29 acres of water rimmed by 0.9 miles of bank. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. Littoral water — the productive band under ~15 ft — makes up 73% of this chart. End to end it runs roughly 0.3 mi, about 0.3 mi across. You'll find it in Gogebic County. The nearest mapped water is Mountain Lake, 2 mi to the southwest.
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 6 to 20 ft game here, winter a 6 to 20 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
