95-acre lake in Timiskaming District, Ontario. The lake tops out around 40 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.
Traced from the shoreline, Jackson Lake runs 96 acres with 2.5 miles of edge. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. The shallow band under 15 ft claims about 47% of the surface — that's where the groceries are. Figure 1 mi of water from one end to the other, 0.3 mi at the beam. The water lies in Timiskaming District. For a second option, Separation Lake lies 1 mi southeast.
When the water first warms, lake whitefish slide up into 12 to 40 ft. There's no big seasonal slide here — summer means 12 to 40 ft, winter 12 to 40 ft. If you only fish one area, make it Deep basin: a deep basin around 40 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 12 to 40 ft | midday & dawn | Break off the point (35 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 12 to 40 ft | dawn | Deep basin (40 ft) | Blade bait vertical, Small jigging spoon |

| Winter | 12 to 40 ft | midday & dawn | Deep basin (40 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, cisco (lake herring) slide up into 10 to 40 ft. There's no big seasonal slide here — summer means 12 to 40 ft, winter 12 to 40 ft. If you only fish one area, make it Deep basin: a deep basin around 40 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (40 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 12 to 40 ft | dawn | Deep basin (40 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |

Early season walleye use the shallows, holding in 4 to 15 ft. Summer is a 15 to 35 ft game here, winter a 20 to 40 ft one. The chart's best answer is Break off the point — drop-off, 35 ft, prime for fall. Best bite is the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Secondary point (5 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (35 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (35 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Deep basin (40 ft) | Jigging spoon + minnow head, Rattle bait |
