690-acre lake in Thunder Bay District, Ontario. The lake tops out around 58 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 692 acres of water rimmed by 10.7 miles of bank. With a shoreline index of 2.9, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 25% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 4 mi end to end and 0.8 mi across at its widest. The water lies in Thunder Bay District. Closest neighbour on DepthScout: Little Moraine Lake, 2 mi north of here.
The spring pattern is a shallow one: lake trout in 10 to 40 ft. As the season builds they drop to 17 to 58 ft, wintering in 15 to 58 ft. Top water on the chart: Deep basin, a deep basin in the 49 ft range, prime in summer. Time it for early morning. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
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 (15 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 17 to 58 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (49 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (15 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 15 to 58 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (49 ft) | White tube jig, Airplane jig |
Come spring, look for lake whitefish tight to the bank in 15 to 45 ft. Expect a summer slide to 17 to 58 ft, then a winter hold in 17 to 58 ft. Start at Deep basin. It's a deep basin holding about 49 ft of water and rates prime come summer. Prime time lands in early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.
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 | 15 to 45 ft | midday & dawn | Break off the point (26 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 17 to 58 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (49 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (26 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 17 to 58 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (49 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 6 ft, rated prime for spring northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
