Rating depth structure for brook trout.

32-acre lake in Algoma District, Ontario. The lake tops out around 80 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). The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Finger Lake runs 32 acres with 1.7 miles of edge. An index of 2.2 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 36% of this chart. End to end it runs roughly 0.7 mi, about 0.2 mi across. You'll find it in Algoma District. For a second option, Clara Lake lies 1 mi south.
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.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. The spot to know is Secondary point, a point in about 11 ft of water that rates prime for brook trout in spring. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Secondary point (11 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (34 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Secondary point (11 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (2 ft) | Small jigging spoon, Tungsten jig + plastic |
Structure-wise the chart holds 5 features, led in depth by Deep basin at roughly 78 ft.
