46-acre lake in Algoma District, Ontario. The lake tops out around 54 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Here is how the season plays out for each species, straight from the data behind the map.
Spring Lake maps at 45 acres behind 1.6 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 40% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 0.6 mi with a 0.3-mi widest point. Algoma District claims this one. Green Lake sits 1 mi east — the closest neighbouring chart.
Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 16 to 54 ft game here, winter a 14 to 54 ft one. The chart's best answer is Deep basin — deep basin, 46 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (14 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 16 to 54 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (46 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (14 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 14 to 54 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (46 ft) | White tube jig, Airplane jig |
Early season burbot use the shallows, holding in 16 to 54 ft. Even in summer they hold at 16 to 54 ft; winter keeps them in 14 to 54 ft. The chart's best answer is Deep basin — deep basin, 46 ft, prime for spring. Best bite is after dark and midday. Tie on a heavy jig + cut bait and you're in the game.
