85-acre lake in Parry Sound District, Ontario. The lake tops out around 60 ft. The depth data here comes from the Ontario MNRF survey of 1974, a decades-old survey (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 86 acres wrapped in 2.8 miles of bank. A middling shoreline index (2.1) gives it some bays to work without being a maze. About 17% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 1.1 mi with a 0.2-mi widest point. It sits in Parry Sound District. Its nearest charted neighbour, Tarver Lake, is 1 mi to the north.
In spring, cisco (lake herring) run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 18 to 60 ft, and winter fish settle into 20 to 60 ft. Deep basin is the standout, a deep basin at roughly 58 ft, rated prime for summer cisco (lake herring). Time it for early morning. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.
