35-acre lake in Algoma District, Ontario. The lake tops out around 43 ft. The depth data here comes from the Ontario MNRF survey of 2021 (an MNRF lake survey). Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 35 acres, worked by 1.2 miles of shoreline. With a 1.5 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 45% of the surface — that's where the groceries are. Figure 0.4 mi of water from one end to the other, 0.3 mi at the beam. Algoma District claims this one. If the bite dies, Gaff Lake is 1 mi to the east.
Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. The chart's best answer is Break off the point — drop-off, 20 ft, prime for summer. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.

|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 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 |
