271-acre lake in Algoma District, Ontario. The lake tops out around 60 ft. The depth data here comes from the Ontario MNRF survey of 1973, a decades-old survey (a transect sounding survey). What follows comes from the same scoring engine that paints the spots above.
The drawn water covers 272 acres wrapped in 5.7 miles of bank, with 5 islands in the mix. An index of 2.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 40% of this chart. End to end it runs roughly 1.5 mi, about 0.6 mi across. It sits in Algoma District. Its nearest charted neighbour, Point Lake, is 2 mi to the south.
Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Secondary point first on the milk run — a point near 5 ft that grades prime for spring. In summer the feeding windows fall in 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 | Secondary point (5 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 (5 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (3 ft) | Small jigging spoon, Tungsten jig + plastic |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 60 ft.
