2,736-acre lake in Algoma District, Ontario. The lake tops out around 220 ft. The depth data here comes from the Ontario MNRF survey of 1966, a decades-old survey (a transect sounding survey). What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 2,749 acres of water rimmed by 40.4 miles of bank, broken up by 28 islands. An index of 5.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 21% of the surface — that's where the groceries are. Call it 8.8 mi long by 2.5 mi wide at the broadest reach. The water lies in Algoma District. The nearest mapped water is Foggy Swiss Lake, 1 mi to the southwest.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Rock reef, a rock pile in the 6 ft range, prime in fall. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Rock reef (6 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (8 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Summer pushes them deeper, 50 to 120 ft, and winter fish settle into 20 to 80 ft. The spot to know is Main-lake point, a point in about 39 ft of water that rates prime for lake trout in spring. Warm-month bites cluster around early morning. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (39 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Break off the point (71 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Rock reef (6 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (71 ft) | White tube jig, Airplane jig |
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 8 to 40 ft for winter. The spot to know is Shoreline point, a point in about 20 ft of water that rates prime for rainbow trout in spring. Plan around early morning and the evening in the warm months. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shoreline point (20 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Rock reef (6 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Secondary point (29 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Rock reef (6 ft) | Jigging spoon, Tube jig (white) |
