9-acre lake in Nipissing District, Ontario. The lake tops out around 33 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 8 acres of water rimmed by 0.7 miles of bank. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 44% of this chart, as modeled. You'll find it in Nipissing District.

In spring, splake run shallow here, mostly 5 to 25 ft. Midsummer fish sit out in 10 to 33 ft before dropping to 7 to 33 ft for winter. Summer splake concentrate at Break off the point, a prime-rated drop-off around 15 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a trolled spoon at the thermocline or a white tube jig (deep) most summer days.
