109-acre lake in Algoma District, Ontario. The lake tops out around 70 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 1975, a decades-old survey (an MNRF lake survey). Below is the species-by-species picture, pulled from the same data the map uses.
Wigwas Lake maps at 109 acres behind 3.7 miles of shoreline. With a shoreline index of 2.6, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 60% of the surface — that's where the groceries are. The basin spans about 0.9 mi end to end and 0.4 mi across at its widest. Algoma District claims this one. Boss Lake sits 1 mi northwest — the closest neighbouring chart.
Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 21 to 70 ft game here, winter an 18 to 70 ft one. The chart's best answer is Deep basin — deep basin, 67 ft, prime for summer. Best bite is early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (30 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 21 to 70 ft | dawn | Deep basin (67 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Break off the point (30 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 18 to 70 ft | dawn | Deep basin (67 ft) | White tube jig, Airplane jig |
Early season burbot use the shallows, holding in 25 to 70 ft. Even in summer they hold at 21 to 70 ft; winter keeps them in 15 to 60 ft. The chart's best answer is Deep basin — deep basin, 67 ft, prime for spring. Best bite is after dark and midday. Tie on a heavy jig + cut bait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Deep basin (67 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 21 to 70 ft | night & midday | Deep basin (67 ft) | Heavy jig + cut bait |
| Fall | 21 to 70 ft | night & dusk | Deep basin (67 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Deep basin (67 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
