42-acre lake in Sudbury District, Ontario. The lake tops out around 26 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 1991 (a transect sounding survey). Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 42 acres of water rimmed by 3 miles of bank, with a single island in the mix. A development index of 3.3 means a maze of bays and points: far more casting targets than a round bowl of the same size. 79% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 0.9 mi with a 0.3-mi widest point. You'll find it in Sudbury District. The nearest mapped water is Paul Lake, 1 mi to the northwest.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 8 to 26 ft, and winter fish settle into 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 26 ft, rated prime for summer 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.
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 | 2 to 15 ft | dawn & dusk | Main-lake point (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 26 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (26 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (6 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (8 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 8 to 26 ft in summer and finish the year down in 8 to 26 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 5 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (5 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 26 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (26 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 26 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (26 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 26 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (26 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 5 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (5 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (8 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (8 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (5 ft) | Tip-ups, Large jigging spoon |

Ghoul Lake is about 26 ft (8 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1991 (a transect sounding survey).
Anglers target brook trout, yellow perch, northern pike on Ghoul Lake. This isn't a survey of the lake — none is on record for it — but an informed estimate from the species Ontario's MNRF recorded in the nearest surveyed lakes, filtered to this lake's depth and habitat.
Shallow bay flat is the top-rated area: a weed flat in about 5 ft of water that rates prime for yellow perch in spring. Open the map above to see every rated 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.
Fishing on Ghoul Lake is regulated by the Ontario fishing regulations (FMZ summary). Check the official Ontario regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
