74,962-acre lake in Timiskaming District, Ontario. The lake tops out around 70 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Lake Timiskaming runs 75,105 acres with 208.1 miles of edge, broken up by 9 islands. A development index of 5.4 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 64% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 53.1 mi of water from one end to the other, 11.2 mi at the beam. You'll find it in Timiskaming District. For a second option, Maidens Lake lies 2 mi southwest.
Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 21 to 70 ft; cold water stacks them in 18 to 70 ft. Deep basin is the standout, a deep basin at roughly 60 ft, rated prime for summer lake trout. Plan around early morning in the warm months. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (18 ft) | Casting spoon over shoals, Jerkbait (shallow) |

Early season lake whitefish use the shallows, holding in 15 to 45 ft. Summer is a 21 to 70 ft game here, winter a 25 to 70 ft one.

It's a drop-off holding about 32 ft of water and rates prime come fall. Prime time lands in the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.

If you only fish one area, make it Shallow bay flat: a weed flat around 6 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
