445-acre lake in Kenora District, Ontario. The lake tops out around 23 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Mars Lake draws 444 acres inside 9.3 miles of shoreline. The 3.2 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 84% of the surface on the model — that's where the groceries are. Figure 3.8 mi of water from one end to the other, 0.6 mi at the beam. You'll find it in Kenora District. The nearest mapped water is An L., 1 mi to the southeast.
Spring walleye on Mars Lake hold shallow, usually 4 to 15 ft. By summer they slide out to 7 to 23 ft, and by winter most fish are in 7 to 23 ft. The chart's best answer is Break off the point — drop-off, 10 ft, prime for fall. Prime time lands in the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).
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 | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 7 to 23 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (10 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 7 to 23 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (10 ft) | Jigging rap, Jig + big minnow |
| Winter | 7 to 23 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (20 ft) | Jigging spoon + minnow head, Rattle bait |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 7 to 23 ft game here, winter a 7 to 23 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.

| 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 | 7 to 23 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 7 to 23 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 7 to 23 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| 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 (10 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (10 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 |
The spring pattern is a shallow one: burbot in 7 to 23 ft. The depth story barely changes: 7 to 23 ft through summer, 6 to 23 ft in winter. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for burbot in spring. Plan around after dark and midday in the warm months. Summer baits: a heavy jig + cut bait gets it done.

Break off the point is the top-rated area: a drop-off in about 10 ft of water that rates prime for walleye in fall. Every other rated spot, per species and season, is on the map above.
For walleye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
