Rating depth structure for lake trout.
Recent public catches load as you reach this section.
114-acre lake in Sudbury District, Ontario. The lake tops out around 65 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 a transect sounding survey by the Ontario MNRF. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 115 acres of water rimmed by 2.9 miles of bank — 2 islands included. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 44% of this chart. Tip to tip the water measures near 0.9 mi with a 0.4-mi widest point. You'll find it in Sudbury District. Closest neighbour on DepthScout: Lance Lake, 2 mi southwest of here.
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.

In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. Main-lake point is the standout, a point at roughly 5 ft, rated prime for spring brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (5 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 (5 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (12 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 20 to 65 ft; cold water stacks them in 16 to 65 ft. Deep basin is the standout, a deep basin at roughly 65 ft, rated prime for summer lake trout. Plan around early morning in the warm months. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
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 (9 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 20 to 65 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (65 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Secondary point (9 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 16 to 65 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (65 ft) | White tube jig, Airplane jig |
Early season lake whitefish use the shallows, holding in 15 to 45 ft. Summer is a 20 to 65 ft game here, winter a 20 to 65 ft one. The chart's best answer is Deep basin — deep basin, 65 ft, prime for summer. Best bite is early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | open water | Small jig + waxworm, Blade bait (small) |
| Summer | 20 to 65 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (65 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Secondary point (9 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 20 to 65 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (65 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season cisco (lake herring) use the shallows, holding in 10 to 40 ft. Summer is a 20 to 65 ft game here, winter a 20 to 60 ft one. The chart's best answer is Deep basin — deep basin, 65 ft, prime for summer. Best bite is early morning. Tie on a vertical flutter spoon (small) or a drop-shot micro plastic and you're in the game.

Ninegee Lake is about 65 ft (20 m) deep at its deepest point. The depth data here comes from a transect sounding survey by the Ontario MNRF.
Anglers target brook trout, lake trout, lake whitefish, cisco (lake herring) on Ninegee Lake.
Deep basin is the top-rated area: a deep basin in about 65 ft of water that rates prime for lake trout in summer. Every other rated spot, per species and season, is on the map above.
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.
