120-acre lake in Thunder Bay District, Ontario. The lake tops out around 18 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Species by species, here's what the data says the year looks like.
The drawn water covers 120 acres wrapped in 2 miles of bank. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 95% of the surface on the model — that's where the groceries are. End to end it runs roughly 0.8 mi, about 0.4 mi across. It sits in Thunder Bay District. Norwegian Lake sits 1 mi north — the closest neighbouring chart.
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is a 5 to 18 ft game here, winter a 5 to 15 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
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 | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 5 to 18 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (8 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (8 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 5 to 18 ft before dropping to 5 to 18 ft for winter. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
