32-acre lake in Lanark County, Ontario. The lake tops out around 15 ft. The depth data here comes from the Ontario MNRF survey of 1968, a decades-old survey (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Peterwhite Lake runs 32 acres with 1.5 miles of edge, broken up by an island. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. Figure 0.4 mi of water from one end to the other, 0.2 mi at the beam. You'll find it in Lanark County. Closest neighbour on DepthScout: Kates Lake, 1 mi east of here.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. The depth story barely changes: 5 to 15 ft through summer, 2 to 15 ft in winter. Top water on the chart: Deep basin, a deep basin in the 15 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 5 to 15 ft | dawn & dusk | Deep basin (15 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (3 ft) | Small spoon (orange), Spinner |
| Winter | 2 to 15 ft | dawn | Deep basin (15 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: rainbow trout sit in 4 to 15 ft that time of year. They don't go far with the seasons — 4 to 15 ft covers summer, 3 to 15 ft covers winter. The spot to know is Break off the point, a drop-off in about 5 ft of water that rates prime for rainbow trout in winter. Warm-month bites cluster around early morning and the evening. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dawn & dusk | Secondary point (7 ft) | Inline spinner (silver), Small spoon |
| Summer | 4 to 15 ft | dawn & dusk | Break off the point (5 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 4 to 15 ft | dawn & dusk | Secondary point (7 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 3 to 15 ft | dawn | Break off the point (5 ft) | Jigging spoon, Tube jig (white) |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 5 to 15 ft game here, winter a 5 to 15 ft one. The chart's best answer is Deep basin — deep basin, 15 ft, prime for fall. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 15 ft | dawn | Deep basin (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 15 ft | midday | Deep basin (15 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 15 ft | midday & dawn | Deep basin (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for pumpkinseed tight to the bank in 1 to 8 ft. They move out to 2 to 10 ft in summer and finish the year down in 5 to 15 ft. If you only fish one area, make it Deep basin: a deep basin around 15 ft that scores prime in winter. Best bite is the evening and early morning. A micro tube or a sponge spider (fly) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | open water | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | open water | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Break off the point (5 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 15 ft | dawn | Deep basin (15 ft) | Tungsten ice jig + plastic, Tiny spoon |
