26-acre lake in Nipissing District, Ontario. The lake tops out around 26 ft. The depth data here comes from the Ontario MNRF survey of 1983 (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Kervin Lake runs 26 acres with 0.9 miles of edge. Nearly circular (index 1.2), so the story is the bottom, not the bank. About 54% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 0.3 mi of water from one end to the other, 0.2 mi at the beam. The water lies in Nipissing District. For a second option, Marian Lake lies 1 mi south.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 8 to 26 ft before dropping to 3 to 20 ft for winter. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 26 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (4 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 26 ft | dawn & dusk | Deep basin (26 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (4 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (16 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, splake run shallow here, mostly 5 to 25 ft. Summer pushes them deeper, 8 to 26 ft, and winter fish settle into 6 to 26 ft. Break off the point is the standout, a drop-off at roughly 16 ft, rated prime for summer splake. Time it for early morning and the evening. You won't need more than a trolled spoon at the thermocline or a white tube jig (deep) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Secondary point (10 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 8 to 26 ft | dawn & dusk | Break off the point (16 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 7 to 26 ft | dawn & dusk | Secondary point (10 ft) | Casting spoon, Jerkbait |
| Winter | 6 to 26 ft | dawn | Break off the point (16 ft) | Jigging spoon tipped with minnow head, Small white tube |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Expect a summer slide to 8 to 26 ft, then a winter hold in 8 to 26 ft. Start at Deep basin. It's a deep basin holding about 26 ft of water and rates prime come fall. Prime time lands in 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 | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 26 ft | dawn | Deep basin (26 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 26 ft | midday | Deep basin (26 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 26 ft | midday & dawn | Deep basin (26 ft) | Tungsten jig + spikes, Rattle spoon (small) |
