168-acre lake in Peterborough County, Ontario. The lake tops out around 20 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.
The drawn water covers 168 acres wrapped in 7.8 miles of bank — 4 islands included. With a shoreline index of 4.3, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 89% of the water is 15 ft or less, the band where the food chain lives. Call it 1.2 mi long by 0.8 mi wide at the broadest reach. Peterborough County claims this one. Wolf Lake sits 1 mi northeast — the closest neighbouring chart.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 6 to 20 ft, and winter fish settle into 6 to 20 ft. Deep basin is the standout, a deep basin at roughly 20 ft, rated prime for fall yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (2 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) |
Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Expect a summer slide to 6 to 20 ft, then a winter hold in 6 to 20 ft. Put Main-lake point first on the milk run — a point near 7 ft that grades prime for fall. In summer the feeding windows fall in early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (7 ft) | Ned rig, Tube jig |
| Summer | 6 to 20 ft | dawn & dusk | Main-lake point (7 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 6 to 20 ft | midday & dawn | Main-lake point (7 ft) | Jerkbait, Blade bait |
| Winter | 6 to 20 ft | midday | Break off the point (3 ft) | Blade bait, Hair jig |
In spring, pumpkinseed run shallow here, mostly 1 to 8 ft. Midsummer fish sit out in 2 to 10 ft before dropping to 6 to 18 ft for winter. Spring pumpkinseed concentrate at Shallow bay flat, a prime-rated weed flat around 2 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a micro tube or a sponge spider (fly) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (2 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (2 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (2 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Deep basin (20 ft) | Tungsten ice jig + plastic, Tiny spoon |
