403-acre lake in Sudbury District, Ontario. The lake tops out around 85 ft. The depth data here comes from the Ontario MNRF survey of 1979, a decades-old survey (a transect sounding survey). What follows comes from the same scoring engine that paints the spots above.
Come spring, look for lake trout tight to the bank in 10 to 40 ft. Expect a summer slide to 26 to 85 ft, then a winter hold in 20 to 80 ft. Start at Deep basin. It's a deep basin holding about 84 ft of water and rates prime come summer. Prime time lands in early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (19 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 26 to 85 ft | dawn | Deep basin (84 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Break off the point (19 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (84 ft) | White tube jig, Airplane jig |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Top water on the chart: Break off the point, a drop-off in the 19 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (19 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (19 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (19 ft) | Tungsten jig + spikes, Rattle spoon (small) |
