Rating depth structure for lake trout.

35-acre lake in Sudbury District, Ontario. The lake tops out around 115 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Blackie's Lake runs 35 acres with 1.3 miles of edge. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. 36% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 0.5 mi, about 0.2 mi across. You'll find it in Sudbury District. Closest neighbour on DepthScout: Walroth Lake, 1 mi north of here.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 35 to 115 ft before dropping to 20 to 80 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 98 ft. Fish it in early morning and you'll meet the bite. 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 (29 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 35 to 115 ft | dawn | Deep basin (98 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (29 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (52 ft) | White tube jig, Airplane jig |
