76-acre lake in Timiskaming District, Ontario. The lake tops out around 70 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. What follows comes from the same scoring engine that paints the spots above.
The outline encloses 76 acres, worked by 2.4 miles of shoreline, broken up by an island. A middling shoreline index (2) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 22% of this chart. Call it 0.6 mi long by 0.4 mi wide at the broadest reach. Timiskaming District claims this one. If the bite dies, Paddle Lake is 1 mi to the south.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 31 ft that scores prime in summer. Best bite is 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 (14 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (31 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (14 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (9 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Midsummer fish sit out in 21 to 70 ft before dropping to 25 to 70 ft for winter. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 66 ft. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (31 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 21 to 70 ft | dawn | Deep basin (66 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (31 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (66 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
In spring, cisco (lake herring) run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 21 to 70 ft before dropping to 20 to 60 ft for winter. Summer cisco (lake herring) concentrate at Deep basin, a prime-rated deep basin around 66 ft. Fish it in early morning and you'll meet the bite. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (31 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 21 to 70 ft | dawn | Deep basin (66 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Deep basin (66 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
