15-acre lake in Algoma District, Ontario. The lake tops out around 31 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 15 acres, worked by 0.9 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze. About 55% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Figure 0.4 mi of water from one end to the other. Algoma District claims this one. If the bite dies, Foucault L. 10 is 0 mi to the south.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 26 ft that scores prime in summer. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| 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 | Deep basin (26 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (14 ft) | Small jigging spoon, Tungsten jig + plastic |
3 pieces of structure are mapped here — Deep basin, around 26 ft, is the deepest of them.
