103-acre lake in Algoma District, Ontario. The lake tops out around 33 ft. The depth data here comes from the Ontario MNRF survey of 1982 (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 103 acres wrapped in 2.7 miles of bank. With a 1.9 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 71% of the surface — that's where the groceries are. Tip to tip the water measures near 1 mi with a 0.4-mi widest point. Algoma District claims this one. If the bite dies, Nina Lake is 0 mi to the north.
Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. The chart's best answer is Break off the point — drop-off, 23 ft, prime for summer. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (7 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (23 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (7 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Back-bay flat (5 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for splake tight to the bank in 5 to 25 ft. They move out to 10 to 33 ft in summer and finish the year down in 7 to 33 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 (7 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 10 to 33 ft | dawn & dusk | Break off the point (23 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 9 to 33 ft | dawn & dusk | Main-lake point (7 ft) | Casting spoon, Jerkbait |
| Winter | 7 to 33 ft | dawn | Break off the point (23 ft) | Jigging spoon tipped with minnow head, Small white tube |
When the water first warms, burbot slide up into 10 to 33 ft. There's no big seasonal slide here — summer means 10 to 33 ft, winter 8 to 33 ft. Start at Deep basin. It's a deep basin holding about 33 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 | 10 to 33 ft | night & dusk | Deep basin (33 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 10 to 33 ft | night & midday | Deep basin (33 ft) | Heavy jig + cut bait |
| Fall | 10 to 33 ft | night & dusk | Deep basin (33 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 8 to 33 ft | night & dusk | Deep basin (33 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 33 ft.
