Rating depth structure for lake trout.

98-acre lake in Kenora District, Ontario. The lake tops out around 76 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 98 acres of water rimmed by 2.2 miles of bank. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. Roughly 33% of the water is 15 ft or less as modeled, the band where the food chain lives. Call it 0.7 mi long by 0.4 mi wide at the broadest reach. You'll find it in Kenora District. For a second option, L. 42 lies 1 mi south.
Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 23 to 76 ft; cold water stacks them in 19 to 76 ft. Deep basin is the standout, a deep basin at roughly 65 ft, rated prime for summer lake trout. Plan around early morning in the warm months. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (19 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 23 to 76 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (65 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (19 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 19 to 76 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (65 ft) | White tube jig, Airplane jig |
Count 6 structure marks on this chart. The deepest, Deep basin, sits near 65 ft.
