120-acre lake in Sudbury District, Ontario. The lake tops out around 20 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. What the data behind the map says about each species, season by season:
Traced from the shoreline, Luke Lake runs 120 acres with 2.8 miles of edge — one island included. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. The shallow band under 15 ft claims about 94% of the surface — that's where the groceries are. Figure 0.6 mi of water from one end to the other, 0.5 mi at the beam. The water lies in Sudbury District. Closest neighbour on DepthScout: Dexter Lake, 1 mi northeast of here.
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Expect a summer slide to 6 to 20 ft, then a winter hold in 6 to 20 ft. Start at Deep basin. It's a deep basin holding about 20 ft of water and rates prime come fall. Prime time lands in 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 (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 20 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 20 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. The spot to know is Break off the point, a drop-off in about 13 ft of water that rates prime for northern pike in fall. Warm-month bites cluster around early morning and the evening. 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 (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (13 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (13 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Break off the point (13 ft) | Tip-ups, Large jigging spoon |
