536-acre lake in Thunder Bay District, Ontario. The lake tops out around 210 ft. The depth data here comes from the Ontario MNRF survey of 1970, a decades-old survey (a transect sounding survey). Every species below gets its seasonal read from the same numbers driving the chart.
When the water first warms, lake trout slide up into 10 to 40 ft. Summer is a 50 to 120 ft game here, winter a 20 to 80 ft one. Start at Break off the point. It's a drop-off holding about 60 ft of water and rates prime come winter. The feeding windows run early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (1 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Break off the point (60 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (1 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (60 ft) | White tube jig, Airplane jig |
Start shallow in spring: cisco (lake herring) sit in 10 to 40 ft that time of year. Warm water sends them out to 40 to 80 ft; cold water stacks them in 20 to 60 ft. Top water on the chart: Break off the point, a drop-off in the 60 ft range, prime in winter. Fish it in early morning and you'll meet the bite. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (210 ft) | Small silver spoon, Tiny swim jig (white) |
