29-acre lake in Sudbury District, Ontario. The lake tops out around 90 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 30 acres of water rimmed by 1.3 miles of bank. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. About 26% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 0.3 mi end to end and 0.3 mi across at its widest. The water lies in Sudbury District. Closest neighbour on DepthScout: Little Superior Lake, 0 mi southwest of here.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 27 to 90 ft, and winter fish settle into 20 to 80 ft. Deep basin is the standout, a deep basin at roughly 90 ft, rated prime for summer lake trout. Time it for early morning. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
