237-acre lake in Cochrane District, Ontario. The lake tops out around 5 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Here's the year, species by species, as the scoring engine sees it.
Korky Lake maps at 238 acres behind 2.4 miles of shoreline. Nearly circular (index 1.1), so the story is the bottom, not the bank. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Tip to tip the water measures near 0.8 mi with a 0.6-mi widest point. Cochrane District claims this one. Its nearest charted neighbour, Jinx Lake, is 1 mi to the south.
Start shallow in spring: yellow perch sit in 1 to 5 ft that time of year. They don't go far with the seasons — 2 to 5 ft covers summer, 2 to 5 ft covers winter. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 5 ft | dawn | Deep basin (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 5 ft | midday | Deep basin (5 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 5 ft | midday & dawn | Deep basin (5 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 1 to 5 ft. Through summer count on 2 to 5 ft; the winter hold is 2 to 5 ft. Start at Shallow bay flat. It's a weed flat holding about 2 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 5 ft | dawn & dusk | Shallow bay flat (2 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 5 ft | midday & dawn | Shallow bay flat (2 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 2 to 5 ft | midday | Shallow bay flat (2 ft) | Tip-ups, Large jigging spoon |
