44-acre lake in Algoma District, Ontario. The lake tops out around 53 ft. The depth data here comes from the Ontario MNRF survey of 1989 (a transect sounding survey). What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 44 acres of water rimmed by 1.8 miles of bank. Index 1.9 on the shoreline: a few honest points and pockets, nothing labyrinthine. 37% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 0.8 mi long by 0.2 mi wide at the broadest reach. You'll find it in Algoma District. For a second option, Stone Lake lies 1 mi northeast.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Top water on the chart: Secondary point, a point in the 10 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Secondary point (10 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (37 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Secondary point (10 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (2 ft) | Small jigging spoon, Tungsten jig + plastic |
