441-acre lake in Kenora District, Ontario. The lake tops out around 56 ft. The depth data here comes from an MNRF lake survey by the Ontario MNRF. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Larson Lake draws 442 acres inside 5.7 miles of shoreline, with 2 islands in the mix. Index 1.9 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 22% of this chart. The basin spans about 1.3 mi end to end and 1.1 mi across at its widest. You'll find it in Kenora District. Closest neighbour on DepthScout: Paulson Lake, 1 mi south of here.
Come spring, look for cisco (lake herring) tight to the bank in 10 to 40 ft. They move out to 17 to 56 ft in summer and finish the year down in 17 to 56 ft. If you only fish one area, make it Deep basin: a deep basin around 56 ft that scores prime in summer. Best bite is early morning. A vertical flutter spoon (small) or a drop-shot micro plastic is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (56 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 17 to 56 ft | dawn | Deep basin (56 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 17 to 56 ft | dawn | Deep basin (56 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring walleye on Larson Lake hold shallow, usually 4 to 15 ft. By summer they slide out to 15 to 35 ft, and by winter most fish are in 20 to 40 ft. The chart's best answer is Main-lake point — point, 20 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).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Secondary point (16 ft) | 1/8 oz jig + minnow, Hair jig |

| Winter | 20 to 40 ft | dusk & dawn | Main-lake point (20 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for sauger tight to the bank in 4 to 18 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 45 ft. Start at Secondary point. It's a point holding about 16 ft of water and rates good come spring. Prime time lands in early morning and the evening. A bottom bouncer + crawler or a 3-way rig with stickbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 18 ft | dawn & dusk | Secondary point (16 ft) | 3/8 oz jig + ringworm, Hair jig + minnow |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (20 ft) | Bottom bouncer + crawler, 3-way rig with stickbait |
| Fall | 12 to 35 ft | dusk & dawn | Break off the point (51 ft) | Jig + big minnow, Blade bait |
| Winter | 15 to 45 ft | dusk | Deep basin (56 ft) | Heavy jigging spoon, Jig + minnow (vertical) |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 15 to 35 ft one. The chart's best answer is Back-bay flat — weed flat, 6 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 | Back-bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow feeding flat (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

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 2 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 (2 ft) | #5 inline spinner, Spoon (red/white) |

| Fall | 6 to 18 ft | midday & dawn | Back-bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Back-bay flat (6 ft) | Tip-ups, Large jigging spoon |

Top water on the chart: Back-bay flat, a weed flat in the 6 ft range, prime in spring. Fish it in the evening and early morning and you'll meet the bite. Throw a double-10 bucktail or a topwater (walk-the-dog / creeper) until the fish tell you otherwise.
