78-acre lake in Sudbury District, Ontario. The lake tops out around 58 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. The depth data here comes from the Ontario MNRF survey of 1972, a decades-old survey (an MNRF lake survey). What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 78 acres of water rimmed by 2.5 miles of bank. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 81% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 0.9 mi with a 0.4-mi widest point. You'll find it in Sudbury District. Closest neighbour on DepthScout: Semple L. 79, 1 mi southeast of here.
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 15 to 35 ft one. The chart's best answer is Shallow bay flat — weed flat, 1 ft, prime for spring. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| 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 (7 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (7 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (50 ft) | Tungsten jig + spikes, Rattle spoon (small) |
