675-acre lake in Thunder Bay District, Ontario. The lake tops out around 121 ft. The depth data here comes from the Ontario MNRF survey of 2003 (an MNRF lake survey). Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 678 acres wrapped in 9 miles of bank — 2 islands included. A development index of 2.5 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 84% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 1.6 mi with a 1.4-mi widest point. It sits in Thunder Bay District. Greenwood Lake sits 3 mi southwest — the closest neighbouring chart.
When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 50 to 120 ft, and by winter most fish are in 20 to 80 ft. If you only fish one area, make it Deep basin: a deep basin around 82 ft that scores prime in summer. In summer the feeding windows fall in 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 | Secondary point (6 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Deep basin (82 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Secondary point (6 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (82 ft) | White tube jig, Airplane jig |
