245-acre lake in Sudbury District, Ontario. The lake tops out around 115 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 248 acres wrapped in 9.2 miles of bank. An index of 4.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Roughly 45% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 2.8 mi, about 0.7 mi across. It sits in Sudbury District. Laura Lake sits 2 mi north — the closest neighbouring chart.
When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 35 to 115 ft, and by winter most fish are in 20 to 80 ft. If you only fish one area, make it Deep basin: a deep basin around 98 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (29 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 35 to 115 ft | dawn | Deep basin (98 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (29 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (52 ft) | White tube jig, Airplane jig |
