58-acre lake in Sudbury District, Ontario. The lake tops out around 80 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 58 acres, worked by 1.4 miles of shoreline. Nearly circular (index 1.3), so the story is the bottom, not the bank. Roughly 14% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 0.5 mi with a 0.3-mi widest point. Sudbury District claims this one. Gail Lake sits 1 mi northwest — the closest neighbouring chart.
Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 24 to 80 ft in summer and finish the year down in 20 to 80 ft. If you only fish one area, make it Deep basin: a deep basin around 80 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (20 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 24 to 80 ft | dawn | Deep basin (80 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (20 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (80 ft) | White tube jig, Airplane jig |
