123-acre lake in Algoma District, Ontario. The lake tops out around 80 ft. The depth data here comes from the Ontario MNRF survey of 1959, a decades-old survey (a transect sounding survey). Species by species, here's what the data says the year looks like.
Jig Lake maps at 123 acres behind 4.1 miles of shoreline, with 2 islands in the mix. An index of 2.6 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 33% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 1.2 mi long by 0.4 mi wide at the broadest reach. Algoma District claims this one. Its nearest charted neighbour, Saw Lake, is 0 mi to the northeast.
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 Main-lake point — point, 14 ft, prime for spring. 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 (14 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (35 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (14 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (19 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Top water on the chart: Back-bay flat, a weed flat in the 4 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow bay flat (19 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (35 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Shallow bay flat (19 ft) | Tungsten jig + spikes, Rattle spoon (small) |
