48-acre lake in Sudbury District, Ontario. The lake tops out around 90 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 49 acres of water rimmed by 1.3 miles of bank — one island included. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. 11% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 0.4 mi end to end and 0.3 mi across at its widest. You'll find it in Sudbury District. For a second option, Lumsden Lake lies 1 mi southeast.
The spring pattern is a shallow one: lake trout in 10 to 40 ft. Midsummer fish sit out in 27 to 90 ft before dropping to 20 to 80 ft for winter. The spot to know is Deep basin, a deep basin in about 86 ft of water that rates prime for lake trout in summer. Plan around early morning in the warm months. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
| 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) |
| Summer | 27 to 90 ft | dawn | Deep basin (86 ft) | White tube jig (deep), Magnum spoon on downrigger |
| 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 | Deep basin (86 ft) | White tube jig, Airplane jig |
