191-acre lake in Sudbury District, Ontario. The lake tops out around 69 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 1978, a decades-old survey (an MNRF lake survey). Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Selkirk Lake draws 192 acres inside 6.9 miles of shoreline. An index of 3.6 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 81% of the surface — that's where the groceries are. End to end it runs roughly 2.5 mi, about 0.4 mi across. You'll find it in Sudbury District. For a second option, Selkirk Lake 48 lies 1 mi southeast.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 21 to 69 ft before dropping to 17 to 69 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 54 ft. Fish it in early morning and you'll meet the bite. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
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 (1 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 21 to 69 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (54 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (1 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 17 to 69 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (54 ft) | White tube jig, Airplane jig |
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 15 to 35 ft one. Start at Shallow bay flat. It's a weed flat holding about 1 ft of water and rates good come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (1 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (1 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | open water | Tungsten jig + spikes, Rattle spoon (small) |
In spring, burbot run shallow here, mostly 21 to 69 ft. Summer keeps them at 21 to 69 ft, and they winter in 15 to 60 ft. Spring burbot concentrate at Deep basin, a prime-rated deep basin around 54 ft. Fish it in after dark and midday and you'll meet the bite. You won't need more than a heavy jig + cut bait most summer days.
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 | 21 to 69 ft chart-limited; documented 25 to 70 ft | night & dusk | Deep basin (54 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 21 to 69 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (54 ft) | Heavy jig + cut bait |
| Fall | 21 to 69 ft chart-limited; documented 30 to 80 ft | night & dusk | Deep basin (54 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Deep basin (54 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 54 ft.

Anglers target lake trout, yellow perch, burbot on Selkirk Lake.
Deep basin is the top-rated area: a deep basin in about 54 ft of water that rates prime for lake trout in summer. The map above holds the full rated-spot list for every species and season.
For lake trout, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
