134-acre lake in Sudbury District, Ontario. The lake tops out around 36 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.
Marie Lake maps at 135 acres behind 5.3 miles of shoreline. The 3.2 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 69% of this chart, as modeled. The basin spans about 1.1 mi end to end and 0.8 mi across at its widest. It sits in Sudbury District. Its nearest charted neighbour, Rose Lake, is 1 mi to the west.
In spring, cisco (lake herring) run shallow here, mostly 9 to 36 ft. Summer keeps them at 11 to 36 ft, and they winter in 11 to 36 ft. Deep basin is the standout, a deep basin at roughly 31 ft, rated prime for spring cisco (lake herring). Time it for early morning. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 36 ft | dawn & dusk | Deep basin (31 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 11 to 36 ft | dawn | Deep basin (31 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (16 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 11 to 36 ft | dawn | Deep basin (31 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 15 to 35 ft for winter. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 4 ft. Fish it in early morning and you'll meet the bite. 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 (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (16 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. The chart's best answer is Shallow bay flat — weed flat, 4 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (16 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (16 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (4 ft) | Tip-ups, Large jigging spoon |
