19-acre lake in Sudbury District, Ontario. The lake tops out around 20 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 18 acres, worked by 0.8 miles of shoreline. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. 79% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.3 mi, about 0.2 mi across. It sits in Sudbury District. Its nearest charted neighbour, Garibaldi L. 4, is 0 mi to the south.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 6 to 20 ft; cold water stacks them in 6 to 20 ft. Deep basin is the standout, a deep basin at roughly 20 ft, rated prime for fall yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 20 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 20 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
