392-acre lake in Thunder Bay District, Ontario. The lake tops out around 98 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1980 (an MNRF lake survey). The season-by-season read for each species follows, from the map's own numbers.
The outline encloses 395 acres, worked by 9.8 miles of shoreline, broken up by 2 islands. A development index of 3.5 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 61% of the water is 15 ft or less, the band where the food chain lives. Figure 2.1 mi of water from one end to the other, 0.8 mi at the beam. Thunder Bay District claims this one. Dakota Lake sits 1 mi north — the closest neighbouring chart.
Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 29 to 98 ft in summer and finish the year down in 20 to 80 ft. If you only fish one area, make it Deep basin: a deep basin around 86 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
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 | Break off the point (13 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 29 to 98 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (86 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Break off the point (13 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (86 ft) | White tube jig, Airplane jig |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. The spot to know is Break off the point, a drop-off in about 13 ft of water that rates prime for yellow perch in summer. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow feeding flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (13 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (13 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (13 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Start at Break off the point. It's a drop-off holding about 13 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (13 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (13 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow feeding flat (6 ft) | Tip-ups, Large jigging spoon |
Come spring, look for burbot tight to the bank in 25 to 70 ft. They move out to 29 to 98 ft in summer and finish the year down in 15 to 60 ft. If you only fish one area, make it Deep basin: a deep basin around 86 ft that scores prime in summer. Best bite is 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 | Deep basin (86 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 29 to 98 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (86 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Deep basin (86 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Break off the point (13 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
