304-acre lake in Nipissing District, Ontario. The lake tops out around 90 ft. The depth data here comes from the Ontario MNRF survey of 1970, a decades-old survey (a transect sounding survey). What follows comes from the same scoring engine that paints the spots above.
On the chart, Timber Lake draws 305 acres inside 8.5 miles of shoreline, with 3 islands in the mix. An index of 3.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 44% of this chart. End to end it runs roughly 2.5 mi, about 1 mi across. The water lies in Nipissing District. Closest neighbour on DepthScout: Campbell Lake, 1 mi northeast of here.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Break off the point is the standout, a drop-off at roughly 21 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Secondary point (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (21 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Secondary point (6 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (21 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, lake trout run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 27 to 90 ft, and winter fish settle into 20 to 80 ft. Deep basin is the standout, a deep basin at roughly 88 ft, rated prime for summer lake trout. Time it for early morning. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (17 ft) | Casting spoon over shoals, Jerkbait (shallow) |

| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (17 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (21 ft) | White tube jig, Airplane jig |
Spring puts splake in skinny water — 5 to 25 ft is the zone. As the season builds they drop to 25 to 60 ft, wintering in 10 to 45 ft. Winter splake concentrate at Break off the point, a prime-rated drop-off around 21 ft. Warm-month bites cluster around early morning and the evening. A trolled spoon at the thermocline or a white tube jig (deep) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (17 ft) | Small casting spoon (gold/orange), Inline spinner |
