81-acre lake in Algoma District, Ontario. The lake tops out around 30 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1970, a decades-old survey (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 81 acres wrapped in 2.9 miles of bank, with 3 islands in the mix. That shoreline is heavily fingered (development index 2.3) — bays, points and pockets everywhere, which multiplies the fishable edge. About 79% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 0.8 mi, about 0.4 mi across. It sits in Algoma District. If the bite dies, Tee Lake is 1 mi to the northwest.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

Come spring, look for brook trout tight to the bank in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Start at Deep basin. It's a deep basin holding about 30 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (30 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (3 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (10 ft) | Small jigging spoon, Tungsten jig + plastic |
6 pieces of structure are mapped here — Deep basin, around 30 ft, is the deepest of them.
