319-acre lake in Algoma District, Ontario. The lake tops out around 8 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 1982 (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 318 acres of water rimmed by 3 miles of bank. Nearly circular (index 1.2), so the story is the bottom, not the bank. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Tip to tip the water measures near 1.1 mi with a 0.7-mi widest point. The water lies in Algoma District. The nearest mapped water is Birch Lake, 1 mi to the northeast.
Spring yellow perch on Cranberry Lake hold shallow, usually 2 to 8 ft. Depth-wise the year is flat: 2 to 8 ft in summer, 2 to 8 ft once it turns cold. The chart's best answer is Back-bay flat — weed flat, 2 ft, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Back-bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 8 ft | dawn | Deep basin (7 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 8 ft | midday | Deep basin (7 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 8 ft | midday & dawn | Deep basin (7 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Summer fish stay in 2 to 8 ft, and winter fish hold in 2 to 8 ft. Spring northern pike concentrate at Back-bay flat, a prime-rated weed flat around 2 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Back-bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 8 ft | dawn & dusk | Back-bay flat (2 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 8 ft | midday & dawn | Back-bay flat (2 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 2 to 8 ft | midday | Back-bay flat (2 ft) | Tip-ups, Large jigging spoon |
When the water first warms, rock bass slide up into 2 to 8 ft. There's no big seasonal slide here — summer means 2 to 8 ft, winter 2 to 8 ft. If you only fish one area, make it Break off the point: a drop-off around 4 ft that scores prime in fall. In summer the feeding windows fall in the evening. Keep a ned rig (small) or a marabou jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Main-lake point (1 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 2 to 8 ft | dusk | Break off the point (4 ft) | Ned rig (small), Marabou jig |
| Fall | 2 to 8 ft | midday | Break off the point (4 ft) | Small tube jig, Inline spinner |
| Winter | 2 to 8 ft | midday | Deep basin (7 ft) | Tungsten jig + plastic, Small spoon + spike |
When the water first warms, pumpkinseed slide up into 1 to 8 ft. There's no big seasonal slide here — summer means 2 to 8 ft, winter 2 to 8 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 the evening and early morning. Keep a micro tube or a sponge spider (fly) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (1 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 8 ft | dusk & dawn | Back-bay flat (2 ft) | Micro tube, Sponge spider (fly) |
| Fall | 2 to 8 ft | dusk & dawn | Back-bay flat (2 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 8 ft | dawn | Back-bay flat (2 ft) | Tungsten ice jig + plastic, Tiny spoon |
The spring pattern is a shallow one: brown bullhead in 2 to 8 ft. The depth story barely changes: 2 to 8 ft through summer, 2 to 8 ft in winter. Top water on the chart: Deep basin, a deep basin in the 7 ft range, prime in winter. Time it for after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Back-bay flat (2 ft) | |
| Summer | 2 to 8 ft | night & dusk | Back-bay flat (2 ft) | |
| Fall | 2 to 8 ft | dusk | Deep basin (7 ft) | |
| Winter | 2 to 8 ft | midday | Deep basin (7 ft) |
Count 6 structure marks on this chart. The deepest, Deep basin, sits near 7 ft.
