408-acre lake in Timiskaming District, Ontario. The lake tops out around 39 ft. The depth data here comes from the Ontario MNRF survey of 1990 (a transect sounding survey). What follows comes from the same scoring engine that paints the spots above.
On the chart, Shack Lake draws 409 acres inside 5.3 miles of shoreline, broken up by 3 islands. Index 1.9 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 81% of this chart. Figure 1.4 mi of water from one end to the other, 0.9 mi at the beam. The water lies in Timiskaming District. For a second option, Headwater Lake lies 1 mi north.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. The spot to know is Break off the point, a drop-off in about 11 ft of water that rates prime for brook trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| 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 (11 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 (11 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for cisco (lake herring) tight to the bank in 10 to 39 ft. Through summer count on 12 to 39 ft; the winter hold is 12 to 39 ft. Start at Deep basin. It's a deep basin holding about 38 ft of water and rates prime come spring. Prime time lands in early morning. A vertical flutter spoon (small) or a drop-shot micro plastic is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 39 ft | dawn & dusk | Deep basin (38 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 12 to 39 ft | dawn | Deep basin (38 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (11 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 12 to 39 ft | dawn | Deep basin (38 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
