156-acre lake in Thunder Bay District, Ontario. The lake tops out around 39 ft. 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.
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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 39 ft | dawn & dusk | Secondary point (16 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 12 to 39 ft | dawn | Deep basin (39 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 8 to 39 ft | dusk & dawn | Main-lake point (9 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 10 to 39 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.
