27-acre lake in Algoma District, Ontario. The lake tops out around 50 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1979, a decades-old survey (an MNRF lake survey). Here is how the season plays out for each species, straight from the data behind the map.
Speck Lake maps at 27 acres behind 1.1 miles of shoreline. With a 1.5 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 49% of the surface — that's where the groceries are. Call it 0.5 mi long. Algoma District claims this one. If the bite dies, Whiskey Lake is 1 mi to the south.
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, 25 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 (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (25 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (1 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (1 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 15 to 50 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 25 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 | Break off the point (25 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 15 to 50 ft | dawn & dusk | Break off the point (25 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Break off the point (25 ft) | Casting spoon, Jerkbait |
| Winter | 10 to 45 ft | dawn | Break off the point (25 ft) | Jigging spoon tipped with minnow head, Small white tube |
Start shallow in spring: rock bass sit in 2 to 10 ft that time of year. Warm water sends them out to 5 to 20 ft; cold water stacks them in 12 to 30 ft. Top water on the chart: Break off the point, a drop-off in the 25 ft range, prime in winter. Fish it in the evening and you'll meet the bite. Throw a ned rig (small) or a marabou jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (1 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (1 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Break off the point (25 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Break off the point (25 ft) | Tungsten jig + plastic, Small spoon + spike |
Structure-wise the chart holds 5 features, led in depth by Deep basin at roughly 50 ft.

Speck Lake is about 50 ft (15 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1979, a decades-old survey (an MNRF lake survey).
Anglers target brook trout, splake, rock bass on Speck Lake.
Break off the point is the top-rated area: a drop-off in about 25 ft of water that rates prime for splake in summer. The map above holds the full rated-spot list for every species and season.
For brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
