61-acre lake in Algoma District, Ontario. The lake tops out around 39 ft. The depth data here comes from the Ontario MNRF survey of 1977, a decades-old survey (a transect sounding survey). What the data behind the map says about each species, season by season:
Drawn out, this is 61 acres of water rimmed by 1.8 miles of bank — 3 islands included. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 51% of this chart. Tip to tip the water measures near 0.5 mi with a 0.3-mi widest point. You'll find it in Algoma District. The nearest mapped water is St. Joe Lake, 1 mi to the northeast.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. Break off the point is the standout, a drop-off at roughly 25 ft, rated prime for summer brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
