Rating depth structure for lake trout.

313-acre lake in Algoma District, Ontario. The lake tops out around 107 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. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 314 acres of water rimmed by 6.4 miles of bank. That shoreline is heavily fingered (development index 2.6) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 48% of the water is 15 ft or less as modeled, the band where the food chain lives. Tip to tip the water measures near 1.7 mi with a 0.9-mi widest point. The water lies in Algoma District. Closest neighbour on DepthScout: Bojack Lake, 1 mi northeast of here.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 32 to 107 ft, and winter fish settle into 20 to 80 ft. Deep basin is the standout, a deep basin at roughly 91 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (27 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 32 to 107 ft | dawn | Deep basin (91 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (27 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (48 ft) | White tube jig, Airplane jig |
