252-acre lake in Kenora District, Ontario. The lake tops out around 19 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. The rest of this page walks each species through its year, using the map's own scoring.
Knob Lake maps at 252 acres behind 4.1 miles of shoreline. With a 1.8 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 88% of the surface on the model — that's where the groceries are. End to end it runs roughly 1.1 mi, about 0.8 mi across. It sits in Kenora District. If the bite dies, Mafeking Lake is 3 mi to the northwest.
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 6 to 19 ft before dropping to 6 to 19 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
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 | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 19 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (16 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 19 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (16 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 19 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (16 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. Summer is a 6 to 19 ft game here, winter a 5 to 15 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.

| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |

When the water first warms, smallmouth bass slide up into 3 to 12 ft. Summer is a 6 to 19 ft game here, winter a 6 to 19 ft one. Start at Main-lake point. It's a point holding about 8 ft of water and rates prime come fall. The feeding windows run early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
