292-acre lake in Thunder Bay District, Ontario. The lake tops out around 72 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 1988 (an MNRF lake survey). Below is the species-by-species picture, pulled from the same data the map uses.
Dakota Lake maps at 293 acres behind 7.6 miles of shoreline — one island included. With a shoreline index of 3.1, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 74% of the surface — that's where the groceries are. The basin spans about 1.6 mi end to end and 0.9 mi across at its widest. It sits in Thunder Bay District. Tinto Lake sits 1 mi south — the closest neighbouring chart.
When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 22 to 72 ft, and by winter most fish are in 18 to 72 ft. If you only fish one area, make it Deep basin: a deep basin around 59 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.
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 (2 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 22 to 72 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (59 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (2 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 18 to 72 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (59 ft) | White tube jig, Airplane jig |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 15 to 35 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 1 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow feeding flat (13 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (3 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Shallow feeding flat (13 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. Start at Shallow bay flat. It's a weed flat holding about 1 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| 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 | Shallow feeding flat (13 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow feeding flat (13 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow feeding flat (13 ft) | Tip-ups, Large jigging spoon |
When the water first warms, burbot slide up into 25 to 70 ft. By summer they slide out to 22 to 72 ft, and by winter most fish are in 15 to 60 ft. If you only fish one area, make it Deep basin: a deep basin around 59 ft that scores prime in spring. In summer the feeding windows fall in after dark and midday. Keep a heavy jig + cut bait rigged through the warm months.
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 | 25 to 70 ft | night & dusk | Deep basin (59 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 22 to 72 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (59 ft) | Heavy jig + cut bait |
| Fall | 22 to 72 ft chart-limited; documented 30 to 80 ft | night & dusk | Deep basin (59 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Deep basin (59 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
