123-acre lake in Algoma District, Ontario. The lake tops out around 80 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 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) |
Start shallow in spring: black bullhead sit in 2 to 9 ft that time of year. Summer pushes them deeper, 3 to 15 ft, and winter fish settle into 10 to 28 ft. The spot to know is Shallow feeding flat, a feeding flat in about 13 ft of water that rates prime for black bullhead in summer. Warm-month bites cluster around after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft | dusk & night | Back-bay flat (4 ft) | |
| Summer | 3 to 15 ft | night & dusk | Shallow feeding flat (13 ft) | |
| Fall | 6 to 20 ft | dusk | Shallow feeding flat (13 ft) | |
| Winter | 10 to 28 ft | midday | Shallow feeding flat (13 ft) |
