98-acre lake in Sudbury District, Ontario. The lake tops out around 20 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. What the data behind the map says about each species, season by season:
The drawn water covers 98 acres wrapped in 3.5 miles of bank. The 2.5 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Roughly 92% of the water is 15 ft or less, the band where the food chain lives. Call it 1.3 mi long by 0.3 mi wide at the broadest reach. It sits in Sudbury District. If the bite dies, Shoe L. is 1 mi to the southwest.
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.

Spring northern pike on Bannerman Lake hold shallow, usually 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (8 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Main-lake point (8 ft) | Tip-ups, Large jigging spoon |
Spring puts lake whitefish in skinny water — 6 to 20 ft is the zone. Summer fish stay in 6 to 20 ft, and winter fish hold in 6 to 20 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 20 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.
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 | 6 to 20 ft chart-limited; documented 15 to 45 ft | midday & dawn | Break off the point (3 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 6 to 20 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (20 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 5 to 20 ft chart-limited; documented 8 to 30 ft | dusk | Main-lake point (8 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 6 to 20 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (20 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
6 pieces of structure are mapped here — Deep basin, around 20 ft, is the deepest of them.

Shallow bay flat is the top-rated area: a weed flat in about 2 ft of water that rates prime for northern pike in spring. Every other rated spot, per species and season, is on the map above.
For northern pike, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
