95-acre lake in Kenora District, Ontario. The lake tops out around 76 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Whale Lake draws 96 acres inside 2.5 miles of shoreline. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 16% of this chart, as modeled. Call it 1.1 mi long by 0.3 mi wide at the broadest reach. You'll find it in Kenora District. Closest neighbour on DepthScout: Lost Axe L., 1 mi north of here.
Spring cisco (lake herring) on Whale Lake hold shallow, usually 10 to 40 ft. They move out to 23 to 76 ft in summer and finish the year down in 20 to 60 ft. Put Deep basin first on the milk run — a deep basin near 65 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a vertical flutter spoon (small) or a drop-shot micro plastic.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (34 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 23 to 76 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (65 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Deep basin (65 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 15 to 35 ft one. Start at Break off the point. It's a drop-off holding about 34 ft of water and rates prime come fall. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| 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 | Break off the point (34 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (34 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (34 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. The spot to know is Shallow bay flat, a feeding flat in about 6 ft of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (19 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |

Anglers target cisco (lake herring), yellow perch, northern pike on Whale Lake.
Deep basin is the top-rated area: a deep basin in about 65 ft of water that rates prime for cisco (lake herring) in summer. Every other rated spot, per species and season, is on the map above.
For cisco (lake herring), the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
