67-acre lake in Algoma District, Ontario. The lake tops out around 50 ft. The depth data here comes from the Ontario MNRF survey of 1965, a decades-old survey (a transect sounding survey). Species by species, here's what the data says the year looks like.
Drawn out, this is 67 acres of water rimmed by 2.7 miles of bank, with a single island in the mix. With a shoreline index of 2.4, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 30% of the surface — that's where the groceries are. Figure 0.8 mi of water from one end to the other, 0.3 mi at the beam. You'll find it in Algoma District. For a second option, Jimmy Lake lies 1 mi west.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Summer brook trout concentrate at Break off the point, a prime-rated drop-off around 20 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
