55-acre lake in Algoma District, Ontario. The lake tops out around 100 ft. The depth data here comes from the Ontario MNRF survey of 1998 (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 56 acres, worked by 2.4 miles of shoreline, with 3 islands in the mix. With a shoreline index of 2.3, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 34% of the surface — that's where the groceries are. Figure 0.8 mi of water from one end to the other, 0.3 mi at the beam. It sits in Algoma District. Its nearest charted neighbour, Cutfinger Lake, is 1 mi to the northwest.
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 Secondary point: a point around 14 ft that scores prime in spring. 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 | Secondary point (14 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Secondary point (14 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (12 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 30 to 100 ft, then a winter hold in 20 to 80 ft. Put Deep basin first on the milk run — a deep basin near 98 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 (30 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 30 to 100 ft | dawn | Deep basin (98 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (30 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (68 ft) | White tube jig, Airplane jig |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 98 ft.
