26-acre lake in Sudbury District, Ontario. The lake tops out around 20 ft. The depth data here comes from the Ontario MNRF survey of 1959, a decades-old survey (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 26 acres of water rimmed by 1.5 miles of bank. The shoreline is moderately structured (index 2.1) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 70% of this chart. End to end it runs roughly 0.5 mi. The water lies in Sudbury District. Closest neighbour on DepthScout: Ketchini Lake, 1 mi southwest of here.
Come spring, look for walleye tight to the bank in 4 to 15 ft. They move out to 6 to 20 ft in summer and finish the year down in 6 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 15 ft that scores prime in fall. Best bite is the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Break off the point (15 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 6 to 20 ft | dusk & dawn | Break off the point (15 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 6 to 20 ft | dusk & night | Break off the point (15 ft) | Jigging rap, Jig + big minnow |
| Winter | 6 to 20 ft | dusk & dawn | Deep basin (20 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Expect a summer slide to 6 to 20 ft, then a winter hold in 6 to 20 ft. Start at Deep basin. It's a deep basin holding about 20 ft of water and rates prime come fall. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| 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 | 6 to 20 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 20 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. The spot to know is Break off the point, a drop-off in about 15 ft of water that rates prime for northern pike in fall. Warm-month bites cluster around early morning and the evening. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (15 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (15 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Break off the point (15 ft) | Tip-ups, Large jigging spoon |

Mallet Lake is about 20 ft (6 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1959, a decades-old survey (a transect sounding survey).
Anglers target walleye, yellow perch, northern pike on Mallet Lake. This isn't a survey of the lake — none is on record for it — but an informed estimate from the species Ontario's MNRF recorded in the nearest surveyed lakes, filtered to this lake's depth and habitat.
Break off the point is the top-rated area: a drop-off in about 15 ft of water that rates prime for walleye in fall. The interactive chart above rates every spot for each species and season.
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.
