2,601-acre lake in Kenora District, Ontario. The lake tops out around 60 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Malachi Lake runs 2,612 acres with 26.5 miles of edge, with 9 islands in the mix. With a shoreline index of 3.7, this water is all arms and coves — edge habitat well beyond its acreage. 30% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 5.5 mi end to end and 2 mi across at its widest. The water lies in Kenora District. The nearest mapped water is South Scot Lake, 4 mi to the northwest.
When the water first warms, cisco (lake herring) slide up into 10 to 40 ft. By summer they slide out to 18 to 60 ft, and by winter most fish are in 20 to 60 ft. If you only fish one area, make it Deep basin: a deep basin around 60 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (60 ft) | Small silver spoon, Tiny swim jig (white) |

Early season walleye use the shallows, holding in 4 to 15 ft. Summer is a 15 to 35 ft game here, winter a 20 to 40 ft one. The chart's best answer is Rock reef — rock pile, 6 ft, prime for spring. Best bite is the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Rock reef (6 ft) | 1/8 oz jig + minnow, Hair jig |

Spring yellow perch on Malachi Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. The chart's best answer is Weed flat — weed flat, 8 ft, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Weed flat (8 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Spring northern pike concentrate at Weed flat, a prime-rated weed flat around 8 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Weed flat (8 ft) | #5 inline spinner, Spoon (red/white) |
