Rating depth structure for lake trout.

156-acre lake in Thunder Bay District, Ontario. The lake tops out around 39 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 1970, a decades-old survey (a transect sounding survey). Below is the species-by-species picture, pulled from the same data the map uses.
Sunset Lake maps at 157 acres behind 3 miles of shoreline. With a 1.7 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 15% of this chart. End to end it runs roughly 1.2 mi, about 0.4 mi across. It sits in Thunder Bay District. Whitefish Lake sits 3 mi west — the closest neighbouring chart.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Break off the point first on the milk run — a drop-off near 20 ft that grades prime for summer. In summer the feeding windows fall in 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 (9 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (9 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (20 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, lake trout slide up into 10 to 39 ft. There's no big seasonal slide here — summer means 12 to 39 ft, winter 10 to 39 ft. If you only fish one area, make it Deep basin: a deep basin around 39 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
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 39 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Secondary point (16 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 12 to 39 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (39 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 8 to 39 ft chart-limited; documented 10 to 50 ft | dusk & dawn | Main-lake point (9 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 10 to 39 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (39 ft) | White tube jig, Airplane jig |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 39 ft.

Sunset Lake is about 39 ft (12 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1970, a decades-old survey (a transect sounding survey).
Anglers target brook trout, lake trout on Sunset Lake.
Deep basin is the top-rated area: a deep basin in about 39 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.
