267-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. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 269 acres wrapped in 5.6 miles of bank, with 2 islands in the mix. A development index of 2.4 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 16% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 1.7 mi, about 0.5 mi across. It sits in Sudbury District. Its nearest charted neighbour, Shack Lake, is 2 mi to the southeast.
When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 24 to 80 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 80 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 (10 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 (10 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (80 ft) | White tube jig, Airplane jig |
When the water first warms, northern pike slide up into 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. Start at Back-bay flat. It's a feeding flat holding about 2 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Back-bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (10 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (10 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (10 ft) | Tip-ups, Large jigging spoon |
