2,079-acre lake in Algoma District, Ontario. The lake tops out around 170 ft. The depth data here comes from the Ontario MNRF survey of 1964, a decades-old survey (a transect sounding survey). Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 2,089 acres of water rimmed by 28.1 miles of bank, with 12 islands in the mix. With a shoreline index of 4.4, this water is all arms and coves — edge habitat well beyond its acreage. 20% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 5.1 mi with a 1.8-mi widest point. You'll find it in Algoma District. For a second option, McIlveen L. 19 lies 2 mi northwest.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. Main-lake point is the standout, a point at roughly 9 ft, rated prime for spring brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (9 ft) | Small inline spinner (gold), Tiny spoon |

Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 50 to 120 ft; cold water stacks them in 20 to 80 ft. Secondary point is the standout, a point at roughly 21 ft, rated prime for spring lake trout. Plan around early morning in the warm months. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
