55-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. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 55 acres of water rimmed by 1.7 miles of bank. Index 1.6 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 43% of this chart, as modeled. Tip to tip the water measures near 0.6 mi with a 0.4-mi widest point. You'll find it in Sudbury District. The nearest mapped water is North Emerson Lake, 1 mi to the west.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Top water on the chart: Break off the point, a drop-off in the 21 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (12 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (21 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

| Winter | 3 to 20 ft | dawn | Break off the point (21 ft) | Small jigging spoon, Tungsten jig + plastic |
