192-acre lake in Kenora District, Ontario. The lake tops out around 13 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 1985 (an MNRF lake survey). Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Martene L. runs 193 acres with 2.6 miles of edge. Nearly circular (index 1.3), 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. Figure 0.9 mi of water from one end to the other, 0.5 mi at the beam. The water lies in Kenora District. Closest neighbour on DepthScout: Bawlb L., 3 mi south of here.
When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 4 to 13 ft, and by winter most fish are in 4 to 13 ft. If you only fish one area, make it Deep basin: a deep basin around 6 ft that scores prime in fall. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
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 (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 13 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 13 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (6 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 13 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (6 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. As the season builds they drop to 4 to 13 ft, wintering in 4 to 13 ft. Top water on the chart: Shallow bay flat, a weed flat in the 1 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.

| Summer | 4 to 13 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (1 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 4 to 13 ft chart-limited; documented 6 to 18 ft | midday & dawn | Deep basin (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 4 to 13 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |

Anglers target yellow perch, northern pike on Martene L..
Deep basin is the top-rated area: a deep basin in about 6 ft of water that rates prime for yellow perch in fall. Scroll up to the map for the complete spot list by 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.
