24-acre lake in Algoma District, Ontario. The lake tops out around 48 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 24 acres, worked by 1.3 miles of shoreline. With a 1.9 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 32% of the surface on the model — that's where the groceries are. Figure 0.5 mi of water from one end to the other, 0.2 mi at the beam. Algoma District claims this one. Its nearest charted neighbour, Glenn L., is 1 mi to the south.
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, 22 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (12 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (22 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (12 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: cisco (lake herring) sit in 10 to 40 ft that time of year. Warm water sends them out to 14 to 48 ft; cold water stacks them in 14 to 48 ft. Top water on the chart: Deep basin, a deep basin in the 41 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (41 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 14 to 48 ft | dawn | Deep basin (41 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (22 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 14 to 48 ft | dawn | Deep basin (41 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Structure-wise the chart holds 5 features, led in depth by Deep basin at roughly 41 ft.
