88-acre lake in Algoma District, Ontario. The lake tops out around 53 ft. The depth data here comes from the Ontario MNRF survey of 1971, 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 89 acres wrapped in 2.7 miles of bank — 3 islands included. With a 2.1 development index there's bank structure worth casting at, in moderation. 39% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.9 mi, about 0.3 mi across. Algoma District claims this one. Fillion L. sits 1 mi east — the closest neighbouring chart.
Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 16 to 53 ft in summer and finish the year down in 13 to 53 ft. If you only fish one area, make it Deep basin: a deep basin around 53 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (20 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 16 to 53 ft | dawn | Deep basin (53 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Break off the point (20 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 13 to 53 ft | dawn | Deep basin (53 ft) | White tube jig, Airplane jig |
