83-acre lake in Sudbury District, Ontario. The lake tops out around 46 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Marguerite Lake draws 85 acres inside 3.2 miles of shoreline. With a shoreline index of 2.5, this water is all arms and coves — edge habitat well beyond its acreage. Littoral water — the productive band under ~15 ft — makes up 65% of this chart, as modeled. The basin spans about 0.7 mi end to end and 0.6 mi across at its widest. You'll find it in Sudbury District. The nearest mapped water is Bluewater Lake, 2 mi to the east.
The spring pattern is a shallow one: splake in 5 to 25 ft. Midsummer fish sit out in 14 to 46 ft before dropping to 10 to 45 ft for winter. The spot to know is Break off the point, a drop-off in about 21 ft of water that rates prime for splake in summer. Plan around early morning and the evening in the warm months. Summer baits: a trolled spoon at the thermocline or a white tube jig (deep) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (12 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 14 to 46 ft | dawn & dusk | Break off the point (21 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (12 ft) | Casting spoon, Jerkbait |
| Winter | 10 to 45 ft | dawn | Break off the point (21 ft) | Jigging spoon tipped with minnow head, Small white tube |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 39 ft.
