Rating depth structure for lake trout.

119-acre lake in Thunder Bay District, Ontario. The lake tops out around 95 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. Here's the year, species by species, as the scoring engine sees it.
MacIntosh Lake maps at 120 acres behind 2.8 miles of shoreline. With a 1.8 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 52% of the surface — that's where the groceries are. Figure 0.8 mi of water from one end to the other, 0.6 mi at the beam. Thunder Bay District claims this one. Its nearest charted neighbour, Nolan Lake, is 1 mi to the northwest.
Spring brook trout on MacIntosh 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 Main-lake point first on the milk run — a point near 2 ft that grades prime for spring. 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 (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (2 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (1 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 29 to 95 ft in summer and finish the year down in 20 to 80 ft. If you only fish one area, make it Deep basin: a deep basin around 89 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 | Secondary point (8 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 29 to 95 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (89 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Secondary point (8 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (63 ft) | White tube jig, Airplane jig |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 89 ft.
Season dates, license requirements, and size and bag limits for Ontario waters are set by the Ontario fishing regulations (FMZ summary) — and special regulations can apply to MacIntosh Lake specifically, so confirm the current rules before you fish.
