155-acre lake in Sudbury District, Ontario. The lake tops out around 105 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Whigham Lake runs 155 acres with 4.8 miles of edge, broken up by an island. A development index of 2.8 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 45% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Call it 1.1 mi long by 0.6 mi wide at the broadest reach. You'll find it in Sudbury District. For a second option, Gravelridge Lake lies 1 mi south.
Early season cisco (lake herring) use the shallows, holding in 10 to 40 ft. Summer is a 40 to 80 ft game here, winter a 20 to 60 ft one. The chart's best answer is Deep basin — deep basin, 89 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (89 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Deep basin (89 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Break off the point (47 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 6 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 (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow bay flat (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (89 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (89 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 6 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 (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
