55-acre lake in Thunder Bay District, Ontario. The lake tops out around 60 ft. The depth data here comes from the Ontario MNRF survey of 1974, a decades-old survey (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 55 acres wrapped in 1.6 miles of bank. With a 1.6 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 31% of the surface — that's where the groceries are. Call it 0.5 mi long by 0.4 mi wide at the broadest reach. Thunder Bay District claims this one. If the bite dies, Mirror Lake is 0 mi to the west.
Spring brook trout on Deception Lake hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Secondary point first on the milk run — a point near 6 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Secondary point (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Secondary point (6 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (17 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 18 to 60 ft in summer and finish the year down in 15 to 60 ft. If you only fish one area, make it Deep basin: a deep basin around 59 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (21 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 18 to 60 ft | dawn | Deep basin (59 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (21 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 15 to 60 ft | dawn | Deep basin (59 ft) | White tube jig, Airplane jig |
The spring pattern is a shallow one: lake whitefish in 15 to 45 ft. Midsummer fish sit out in 18 to 60 ft before dropping to 18 to 60 ft for winter. The spot to know is Deep basin, a deep basin in about 59 ft of water that rates prime for lake whitefish in summer. Plan around early morning in the warm months. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (52 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 18 to 60 ft | dawn | Deep basin (59 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (21 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 18 to 60 ft | midday & dawn | Deep basin (59 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
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 Back-bay flat. It's a weed flat holding about 8 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 | Back-bay flat (8 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (17 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (17 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Back-bay flat (8 ft) | Tip-ups, Large jigging spoon |
Come spring, look for smallmouth bass tight to the bank in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 20 to 45 ft. Start at Main-lake point. It's a point holding about 21 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Secondary point (6 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (21 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (21 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (52 ft) | Blade bait, Hair jig |
The spring pattern is a shallow one: rock bass in 2 to 10 ft. Midsummer fish sit out in 5 to 20 ft before dropping to 12 to 30 ft for winter. The spot to know is Secondary point, a point in about 6 ft of water that rates prime for rock bass in summer. Plan around the evening in the warm months. Summer baits: a ned rig (small) or a marabou jig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Secondary point (6 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Secondary point (6 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Main-lake point (21 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Deep basin (59 ft) | Tungsten jig + plastic, Small spoon + spike |
