418-acre lake in Kenora District, Ontario. The lake tops out around 27 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. Here is how the season plays out for each species, straight from the data behind the map.
The outline encloses 418 acres, worked by 6.4 miles of shoreline. That shoreline is heavily fingered (development index 2.2) — bays, points and pockets everywhere, which multiplies the fishable edge. About 81% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 2 mi end to end and 0.8 mi across at its widest. It sits in Kenora District. If the bite dies, Knob Lake is 3 mi to the southeast.
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 8 to 27 ft; cold water stacks them in 8 to 27 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
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 | 8 to 27 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (23 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 27 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (23 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 27 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (23 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (12 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (12 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
6 pieces of structure are mapped here — Deep basin, around 23 ft, is the deepest of them.

Mafeking Lake is about 27 ft (8 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target yellow perch, northern pike on Mafeking Lake.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for yellow perch in spring. The interactive chart above rates every spot for each species and season.
For yellow perch, 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.
