26-acre lake in Cochrane District, Ontario. The lake tops out around 40 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Here is how the season plays out for each species, straight from the data behind the map.
Pearce No. 34 maps at 26 acres behind 1.2 miles of shoreline, broken up by an island. With a 1.7 development index there's bank structure worth casting at, in moderation. Roughly 38% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 0.5 mi end to end and 0.2 mi across at its widest. Cochrane District claims this one. Gertrude Lake sits 0 mi southeast — the closest neighbouring chart.
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. The spot to know is Back-bay flat, a weed flat in about 6 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 | 3 to 12 ft | midday & dawn | Back-bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (32 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (32 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (40 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 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 | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Back-bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Back-bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Back-bay flat (6 ft) | Tip-ups, Large jigging spoon |
