140-acre lake in Algoma District, Ontario. The lake tops out around 115 ft. The depth data here comes from the Ontario MNRF survey of 2009 (a transect sounding survey). Species by species, here's what the data says the year looks like.
Black Lake maps at 141 acres behind 2.6 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 15% of the surface — that's where the groceries are. Figure 0.8 mi of water from one end to the other, 0.5 mi at the beam. Algoma District claims this one. Its nearest charted neighbour, Makela L., is 1 mi to the west.
Spring brook trout on Black Lake hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Secondary point first on the milk run — a point near 10 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Secondary point (10 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Secondary point (10 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (4 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 35 to 115 ft in summer and finish the year down in 20 to 80 ft. If you only fish one area, make it Deep basin: a deep basin around 114 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (37 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 35 to 115 ft | dawn | Deep basin (114 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (37 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (114 ft) | White tube jig, Airplane jig |
