220-acre lake in Sudbury District, Ontario. The lake tops out around 10 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 1983 (an MNRF lake survey). The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 219 acres wrapped in 4.8 miles of bank, with a single island in the mix. With a shoreline index of 2.3, this water is all arms and coves — edge habitat well beyond its acreage. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 1.3 mi with a 0.6-mi widest point. Sudbury District claims this one. If the bite dies, Sample Lake is 3 mi to the northeast.
The spring pattern is a shallow one: yellow perch in 3 to 10 ft. The depth story barely changes: 3 to 10 ft through summer, 3 to 10 ft in winter. Top water on the chart: Deep basin, a deep basin in the 5 ft range, prime in fall. 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 10 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 10 ft | dawn | Deep basin (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 10 ft | midday | Deep basin (5 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 10 ft | midday & dawn | Deep basin (5 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 3 to 10 ft, and by winter most fish are in 3 to 10 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 1 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 3 to 10 ft | dawn & dusk | Break off the point (2 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 3 to 10 ft | midday & dawn | Break off the point (2 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 3 to 10 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
