169-acre lake in Thunder Bay District, Ontario. The lake tops out around 59 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. What the data behind the map says about each species, season by season:
Mackenzie Lake maps at 171 acres behind 5.6 miles of shoreline. That shoreline is heavily fingered (development index 3) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 66% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 1.2 mi, about 0.8 mi across. Thunder Bay District claims this one. Its nearest charted neighbour, Moose Lake, is 1 mi to the southeast.
Spring brook trout on Mackenzie 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 Break off the point first on the milk run — a drop-off near 27 ft that grades prime for summer. 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 | Main-lake point (15 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (27 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (15 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 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 18 to 59 ft in summer and finish the year down in 15 to 59 ft. If you only fish one area, make it Deep basin: a deep basin around 50 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.
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 (15 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 18 to 59 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (50 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (15 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 15 to 59 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (50 ft) | White tube jig, Airplane jig |
Come spring, look for burbot tight to the bank in 18 to 59 ft. Through summer count on 18 to 59 ft; the winter hold is 15 to 59 ft. If you only fish one area, make it Deep basin: a deep basin around 50 ft that scores prime in spring. Best bite is after dark and midday. A heavy jig + cut bait is the honest summer answer here.
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 | 18 to 59 ft chart-limited; documented 25 to 70 ft | night & dusk | Deep basin (50 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 18 to 59 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (50 ft) | Heavy jig + cut bait |
| Fall | 18 to 59 ft chart-limited; documented 30 to 80 ft | night & dusk | Deep basin (50 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 59 ft chart-limited; documented 15 to 60 ft | night & dusk | Deep basin (50 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
6 pieces of structure are mapped here — Deep basin, around 50 ft, is the deepest of them.

Mackenzie Lake is about 59 ft (18 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target brook trout, lake trout, burbot on Mackenzie Lake.
Deep basin is the top-rated area: a deep basin in about 50 ft of water that rates prime for lake trout in summer. The interactive chart above rates every spot for each species and season.
For brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
