174-acre lake in Sudbury District, Ontario. The lake tops out around 81 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 174 acres, worked by 4.1 miles of shoreline. An index of 2.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 48% of the surface on the model — that's where the groceries are. Call it 1.2 mi long by 0.5 mi wide at the broadest reach. Sudbury District claims this one. Leask Lake 44 sits 2 mi south — the closest neighbouring chart.
When the water first warms, lake trout slide up into 10 to 40 ft. Summer is a 24 to 81 ft game here, winter a 20 to 80 ft one. Start at Deep basin. It's a deep basin holding about 69 ft of water and rates prime come summer. The feeding windows run 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 (20 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 24 to 81 ft | dawn | Deep basin (69 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 (69 ft) | White tube jig, Airplane jig |
Start shallow in spring: lake whitefish sit in 15 to 45 ft that time of year. Warm water sends them out to 24 to 81 ft; cold water stacks them in 25 to 70 ft. Top water on the chart: Deep basin, a deep basin in the 69 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (36 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 24 to 81 ft | dawn | Deep basin (69 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (20 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (69 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, burbot slide up into 25 to 70 ft. Summer is a 24 to 81 ft game here, winter a 15 to 60 ft one. Start at Deep basin. It's a deep basin holding about 69 ft of water and rates prime come spring. The feeding windows run after dark and midday. Keep a heavy jig + cut bait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Deep basin (69 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 24 to 81 ft | night & midday | Deep basin (69 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Deep basin (69 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Break off the point (36 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
