196-acre lake in Sudbury District, Ontario. The lake tops out around 124 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Below is the species-by-species picture, pulled from the same data the map uses.
Ketchiwaboose Lake maps at 196 acres behind 5.4 miles of shoreline. With a shoreline index of 2.8, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 40% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 1.3 mi end to end and 0.6 mi across at its widest. Sudbury District claims this one. Cabot L. 3 sits 0 mi east — the closest neighbouring chart.
Come spring, look for splake tight to the bank in 5 to 25 ft. They move out to 25 to 60 ft in summer and finish the year down in 10 to 45 ft. If you only fish one area, make it Break off the point: a drop-off around 56 ft that scores prime in summer. Best bite is early morning and the evening. A trolled spoon at the thermocline or a white tube jig (deep) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (31 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 25 to 60 ft | dawn & dusk | Break off the point (56 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (31 ft) | Casting spoon, Jerkbait |
| Winter | 10 to 45 ft | dawn | Break off the point (56 ft) | Jigging spoon tipped with minnow head, Small white tube |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Top water on the chart: Shallow bay flat, a weed flat in the 6 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow bay flat (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (105 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (105 ft) | Tungsten jig + spikes, Rattle spoon (small) |
6 pieces of structure are mapped here — Deep basin, around 105 ft, is the deepest of them.
