Rating depth structure for brook trout.

339-acre lake in Algoma District, Ontario. The lake tops out around 65 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 1971, a decades-old survey (a transect sounding survey). Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 340 acres of water rimmed by 16.4 miles of bank, with 6 islands in the mix. That shoreline is heavily fingered (development index 6.3) — bays, points and pockets everywhere, which multiplies the fishable edge. About 58% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 2.1 mi, about 1.4 mi across. You'll find it in Algoma District. The nearest mapped water is Browne Lake, 3 mi to the southwest.
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.

In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. Break off the point is the standout, a drop-off at roughly 12 ft, rated prime for summer brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| 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 | Break off the point (12 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 (12 ft) | Small jigging spoon, Tungsten jig + plastic |
6 pieces of structure are mapped here — Deep basin, around 60 ft, is the deepest of them.
