Rating depth structure for lake trout.
Recent public catches load as you reach this section.
147-acre lake in Thunder Bay District, Ontario. The lake tops out around 135 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. What the data behind the map says about each species, season by season:
The outline encloses 148 acres, worked by 3.1 miles of shoreline. With a 1.8 development index there's bank structure worth casting at, in moderation. Roughly 10% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 1.2 mi, about 0.3 mi across. It sits in Thunder Bay District. If the bite dies, Squeers Lake is 1 mi to the southeast.
Come spring, look for lake trout tight to the bank in 10 to 40 ft. Expect a summer slide to 50 to 120 ft, then a winter hold in 20 to 80 ft. Start at Deep basin. It's a deep basin holding about 115 ft of water and rates prime come summer. Prime time lands in early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (34 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Deep basin (115 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (34 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (61 ft) | White tube jig, Airplane jig |
Come spring, look for burbot tight to the bank in 25 to 70 ft. Expect a summer slide to 50 to 120 ft, then a winter hold in 15 to 60 ft. Start at Deep basin. It's a deep basin holding about 115 ft of water and rates prime come summer. Prime time lands in after dark and midday. A heavy jig + cut bait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Break off the point (61 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 50 to 120 ft | night & midday | Deep basin (115 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Break off the point (61 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Break off the point (61 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
