89-acre lake in Sudbury District, Ontario. The lake tops out around 89 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 89 acres of water rimmed by 1.4 miles of bank. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. Roughly 22% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 0.5 mi of water from one end to the other, 0.4 mi at the beam. The water lies in Sudbury District. Closest neighbour on DepthScout: Puswawa Lake, 1 mi northwest of here.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Shallow bay flat is the standout, a weed flat at roughly 6 ft, rated good for spring brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (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 |

Spring puts splake in skinny water — 5 to 25 ft is the zone. As the season builds they drop to 25 to 60 ft, wintering in 10 to 45 ft. Summer splake concentrate at Shoreline break, a prime-rated drop-off around 40 ft. Warm-month bites cluster around early morning and the evening. A trolled spoon at the thermocline or a white tube jig (deep) covers the summer program.
