119-acre lake in Algoma District, Ontario. The lake tops out around 71 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 119 acres, worked by 2.9 miles of shoreline. A middling shoreline index (1.9) gives it some bays to work without being a maze. 48% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 1 mi of water from one end to the other, 0.4 mi at the beam. It sits in Algoma District. Carpenter Lake sits 2 mi south — the closest neighbouring chart.
When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 32 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (32 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (18 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 21 to 71 ft, then a winter hold in 18 to 71 ft. Put Deep basin first on the milk run — a deep basin near 60 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (18 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 21 to 71 ft | dawn | Deep basin (60 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (18 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 18 to 71 ft | dawn | Deep basin (60 ft) | White tube jig, Airplane jig |
