97-acre lake in Sudbury District, Ontario. The lake tops out around 51 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Species by species, here's what the data says the year looks like.
The drawn water covers 98 acres wrapped in 2.7 miles of bank. With a 2 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 49% of this chart, as modeled. Tip to tip the water measures near 0.8 mi with a 0.4-mi widest point. Sudbury District claims this one. Chlorus Lake sits 2 mi northwest — the closest neighbouring chart.
Come spring, look for splake tight to the bank in 5 to 25 ft. They move out to 15 to 51 ft in summer and finish the year down in 10 to 45 ft. If you only fish one area, make it Break off the point: a drop-off around 23 ft that scores prime in summer. Best bite is early morning and the evening. A trolled spoon at the thermocline or a white tube jig (deep) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (13 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 15 to 51 ft | dawn & dusk | Break off the point (23 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (13 ft) | Casting spoon, Jerkbait |
| Winter | 10 to 45 ft | dawn | Break off the point (23 ft) | Jigging spoon tipped with minnow head, Small white tube |
When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 6 ft that scores prime in spring. In summer the feeding windows fall in 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 | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
