600-acre lake in Thunder Bay District, Ontario. The lake tops out around 10 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 a transect sounding survey by the Ontario MNRF. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 603 acres, worked by 5.9 miles of shoreline — 2 islands included. With a 1.7 development index there's bank structure worth casting at, in moderation. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Tip to tip the water measures near 1.5 mi with a 1.1-mi widest point. It sits in Thunder Bay District. Seagram Lake sits 6 mi east — the closest neighbouring chart.
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.

Start shallow in spring: cisco (lake herring) sit in 3 to 10 ft that time of year. They don't go far with the seasons — 3 to 10 ft covers summer, 3 to 10 ft covers winter. The spot to know is Deep basin, a deep basin in about 10 ft of water that rates prime for cisco (lake herring) in spring. Warm-month bites cluster around early morning. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.
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 | 3 to 10 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Deep basin (10 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 3 to 10 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (10 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 2 to 10 ft chart-limited; documented 5 to 25 ft | dusk & dawn | Break off the point (5 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 3 to 10 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (10 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
In spring, walleye run shallow here, mostly 3 to 10 ft. Summer keeps them at 3 to 10 ft, and they winter in 3 to 10 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 5 ft. Fish it in the evening and early morning and you'll meet the bite. 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 | 3 to 10 ft chart-limited; documented 4 to 15 ft | dusk & dawn | Main-lake point (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 3 to 10 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (5 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 3 to 10 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (5 ft) | Jigging rap, Jig + big minnow |
| Winter | 3 to 10 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (10 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 10 ft. The depth story barely changes: 3 to 10 ft through summer, 3 to 10 ft in winter. The spot to know is Back-bay flat, a weed flat in about 3 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 10 ft chart-limited; documented 3 to 12 ft | midday & dawn | Back-bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 10 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 10 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 10 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (10 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. Summer is a 3 to 10 ft game here, winter a 3 to 10 ft one. Start at Shallow bay flat. It's a weed flat holding about 2 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.

McBean Lake is about 10 ft (3 m) deep at its deepest point. The depth data here comes from a transect sounding survey by the Ontario MNRF.
Anglers target cisco (lake herring), walleye, yellow perch, northern pike on McBean Lake.
Deep basin is the top-rated area: a deep basin in about 10 ft of water that rates prime for cisco (lake herring) in spring. The map above holds the full rated-spot list for every species and season.
For cisco (lake herring), the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
