66-acre lake in Algoma District, Ontario. The lake tops out around 36 ft. The depth data here comes from the Ontario MNRF survey of 2021 (an MNRF lake survey). The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 67 acres of water rimmed by 1.5 miles of bank. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. Roughly 18% of the water is 15 ft or less, the band where the food chain lives. Call it 0.5 mi long by 0.3 mi wide at the broadest reach. The water lies in Algoma District. The nearest mapped water is Two Horse Lake, 2 mi to the west.
In spring, splake run shallow here, mostly 5 to 25 ft. Summer pushes them deeper, 11 to 36 ft, and winter fish settle into 8 to 36 ft. Break off the point is the standout, a drop-off at roughly 33 ft, rated prime for summer splake. Time it for early morning and the evening. You won't need more than a trolled spoon at the thermocline or a white tube jig (deep) most summer days.
