45-acre lake in Algoma District, Ontario. The lake tops out around 34 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 44 acres of water rimmed by 1.7 miles of bank. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. About 41% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 0.4 mi end to end and 0.4 mi across at its widest. The water lies in Algoma District. For a second option, McKiggan Lake lies 3 mi southwest.
Spring puts splake in skinny water — 5 to 25 ft is the zone. As the season builds they drop to 10 to 34 ft, wintering in 8 to 34 ft. Summer splake concentrate at Break off the point, a prime-rated drop-off around 15 ft. Warm-month bites cluster around early morning and the evening. A trolled spoon at the thermocline or a white tube jig (deep) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (9 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 10 to 34 ft | dawn & dusk | Break off the point (15 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 34 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon, Jerkbait |
| Winter | 8 to 34 ft | dawn | Break off the point (15 ft) | Jigging spoon tipped with minnow head, Small white tube |
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 7 to 34 ft for winter. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 15 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (9 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (15 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 34 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 34 ft | dawn | Break off the point (15 ft) | Jigging spoon, Tube jig (white) |
