152-acre lake in Algoma District, Ontario. The lake tops out around 90 ft. The depth data here comes from the Ontario MNRF survey of 1968, a decades-old survey (a transect sounding survey). Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 153 acres wrapped in 6.2 miles of bank, broken up by 2 islands. An index of 3.6 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 75% of the surface — that's where the groceries are. Call it 1.7 mi long by 0.5 mi wide at the broadest reach. Algoma District claims this one. Gaudry L. 21 (Moon L.) sits 1 mi south — the closest neighbouring chart.
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, 10 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 (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (10 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (6 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (10 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, lake trout slide up into 10 to 40 ft. Summer is a 27 to 90 ft game here, winter a 20 to 80 ft one. Start at Deep basin. It's a deep basin holding about 85 ft of water and rates prime come summer. The feeding windows run early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (10 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 27 to 90 ft | dawn | Deep basin (85 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Break off the point (10 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (85 ft) | White tube jig, Airplane jig |
