Rating depth structure for lake trout.
Shared by DepthScout anglers. Exact spots stay private, always.
129-acre lake in Sudbury District, Ontario. The lake tops out around 55 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 130 acres of water rimmed by 3.7 miles of bank. With a shoreline index of 2.3, this water is all arms and coves — edge habitat well beyond its acreage. 38% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 0.9 mi of water from one end to the other, 0.7 mi at the beam. You'll find it in Sudbury District. Closest neighbour on DepthScout: Marion L., 1 mi west of here.
The spring pattern is a shallow one: lake trout in 10 to 40 ft. Midsummer fish sit out in 17 to 55 ft before dropping to 14 to 55 ft for winter. The spot to know is Deep basin, a deep basin in about 47 ft of water that rates prime for lake trout in summer. Plan around early morning in the warm months. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (14 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 17 to 55 ft | dawn | Deep basin (47 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (14 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 14 to 55 ft | dawn | Deep basin (47 ft) | White tube jig, Airplane jig |
Count 6 structure marks on this chart. The deepest, Deep basin, sits near 47 ft.
