31-acre lake in Nipissing District, Ontario. The lake tops out around 33 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. What follows comes from the same scoring engine that paints the spots above.
Claude Lake maps at 30 acres behind 1.2 miles of shoreline. With a 1.5 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 51% of this chart, as modeled. End to end it runs roughly 0.4 mi, about 0.3 mi across. It sits in Nipissing District. Bena Lake sits 2 mi southwest — the closest neighbouring chart.
When the water first warms, lake trout slide up into 8 to 33 ft. There's no big seasonal slide here — summer means 10 to 33 ft, winter 8 to 33 ft. If you only fish one area, make it Deep basin: a deep basin around 28 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 33 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 10 to 33 ft | dawn | Deep basin (28 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 7 to 33 ft | dusk & dawn | Main-lake point (8 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 8 to 33 ft | dawn | Deep basin (28 ft) | White tube jig, Airplane jig |
Come spring, look for splake tight to the bank in 5 to 25 ft. Expect a summer slide to 10 to 33 ft, then a winter hold in 7 to 33 ft. Start at Break off the point. It's a drop-off holding about 15 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A trolled spoon at the thermocline or a white tube jig (deep) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 10 to 33 ft | dawn & dusk | Break off the point (15 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 9 to 33 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait |
| Winter | 7 to 33 ft | dawn | Break off the point (15 ft) | Jigging spoon tipped with minnow head, Small white tube |
Start shallow in spring: cisco (lake herring) sit in 8 to 33 ft that time of year. They don't go far with the seasons — 10 to 33 ft covers summer, 10 to 33 ft covers winter. The spot to know is Deep basin, a deep basin in about 28 ft of water that rates prime for cisco (lake herring) in spring. Warm-month bites cluster around early morning. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 33 ft | dawn & dusk | Deep basin (28 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 10 to 33 ft | dawn | Deep basin (28 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (15 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 10 to 33 ft | dawn | Deep basin (28 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 10 to 33 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 4 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (28 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 10 to 33 ft | midday | Deep basin (28 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 10 to 33 ft | midday & dawn | Deep basin (28 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: pumpkinseed sit in 1 to 8 ft that time of year. Summer pushes them deeper, 2 to 10 ft, and winter fish settle into 6 to 18 ft. The spot to know is Shallow bay flat, a weed flat in about 4 ft of water that rates prime for pumpkinseed in spring. Warm-month bites cluster around the evening and early morning. Throw a micro tube or a sponge spider (fly) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (4 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (4 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (4 ft) | Tungsten ice jig + plastic, Tiny spoon |
Come spring, look for brown bullhead tight to the bank in 2 to 8 ft. Expect a summer slide to 3 to 12 ft, then a winter hold in 10 to 25 ft. Start at Shallow bay flat. It's a weed flat holding about 4 ft of water and rates prime come spring. Prime time lands in after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (4 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (4 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (4 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (28 ft) |
