912-acre lake in Thunder Bay District, Ontario. The lake tops out around 115 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 an MNRF lake survey by the Ontario MNRF. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 916 acres, worked by 6.7 miles of shoreline, with 4 islands in the mix. With a 1.6 development index there's bank structure worth casting at, in moderation. Roughly 20% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 1.6 mi end to end and 1.3 mi across at its widest. Thunder Bay District claims this one. If the bite dies, Church Lake is 1 mi to the northwest.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

When the water first warms, lake trout slide up into 10 to 40 ft. Summer is a 35 to 115 ft game here, winter a 20 to 80 ft one. Start at Deep basin. It's a deep basin holding about 113 ft of water and rates prime come summer. The feeding windows run 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 (1 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 35 to 115 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (113 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 (76 ft) | White tube jig, Airplane jig |
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. Feeding flat is the standout, a feeding flat at roughly 25 ft, rated good for summer walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (1 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Feeding flat (25 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Main-lake point (1 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | open water | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Top water on the chart: Feeding flat, a feeding flat in the 25 ft range, prime in summer. Time it for early morning. 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 | Feeding flat (25 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | open water | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Feeding flat (25 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a feeding flat around 1 ft that scores prime in spring. In summer the feeding windows fall in 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 | Feeding flat (25 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (1 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
When the water first warms, burbot slide up into 25 to 70 ft. Summer is a 35 to 115 ft game here, winter a 15 to 60 ft one. Start at Deep basin. It's a deep basin holding about 113 ft of water and rates prime come summer. The feeding windows run 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 | Break off the point (76 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 35 to 115 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (113 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Break off the point (76 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Break off the point (76 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Spring puts sauger in skinny water — 4 to 18 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 45 ft. Main-lake point is the standout, a point at roughly 1 ft, rated good for spring sauger. Plan around early morning and the evening in the warm months. A bottom bouncer + crawler or a 3-way rig with stickbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 18 ft | dawn & dusk | Main-lake point (1 ft) | 3/8 oz jig + ringworm, Hair jig + minnow |
| Summer | 10 to 30 ft | dawn & dusk | open water | Bottom bouncer + crawler, 3-way rig with stickbait |
| Fall | 12 to 35 ft | dusk & dawn | open water | Jig + big minnow, Blade bait |
| Winter | 15 to 45 ft | dusk | open water | Heavy jigging spoon, Jig + minnow (vertical) |
