86-acre lake in Timiskaming District, Ontario. The lake tops out around 66 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 1993 (an MNRF lake survey). Here's the year, species by species, as the scoring engine sees it.
On the chart, Tremble Lake draws 85 acres inside 2.5 miles of shoreline. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 76% of this chart. Tip to tip the water measures near 0.6 mi with a 0.4-mi widest point. You'll find it in Timiskaming District. For a second option, Bond Lake lies 1 mi southwest.
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 3 ft, rated prime for winter 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 (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (3 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (1 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (3 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season cisco (lake herring) use the shallows, holding in 10 to 40 ft. Summer is a 20 to 66 ft game here, winter a 20 to 60 ft one. The chart's best answer is Deep basin — deep basin, 64 ft, prime for summer. Best bite is early morning. Tie on a vertical flutter spoon (small) or a drop-shot micro plastic and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (64 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 20 to 66 ft | dawn | Deep basin (64 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (3 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Deep basin (64 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
