25-acre lake in Algoma District, Ontario. The lake tops out around 40 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Black Lake draws 24 acres inside 1.4 miles of shoreline. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. The shallow band under 15 ft claims about 56% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 0.6 mi. The water lies in Algoma District. For a second option, Walton Lake lies 1 mi northeast.
In spring, splake run shallow here, mostly 5 to 25 ft. Summer pushes them deeper, 12 to 40 ft, and winter fish settle into 9 to 40 ft. Break off the point is the standout, a drop-off at roughly 18 ft, rated prime for summer splake. Time it for early morning and the evening. You won't need more than a trolled spoon at the thermocline or a white tube jig (deep) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (10 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 12 to 40 ft | dawn & dusk | Break off the point (18 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (10 ft) | Casting spoon, Jerkbait |
| Winter | 9 to 40 ft | dawn | Break off the point (18 ft) | Jigging spoon tipped with minnow head, Small white tube |
Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 34 ft.
