406-acre lake in Algoma District, Ontario. The lake tops out around 50 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 1966, a decades-old survey (a transect sounding survey). What follows comes from the same scoring engine that paints the spots above.
On the chart, Maquon Lake draws 407 acres inside 7.3 miles of shoreline, with 11 islands in the mix. With a shoreline index of 2.6, this water is all arms and coves — edge habitat well beyond its acreage. 42% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 2 mi long by 0.8 mi wide at the broadest reach. The water lies in Algoma District. Closest neighbour on DepthScout: Wabigoon Lake, 2 mi southwest of here.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Secondary point is the standout, a point at roughly 8 ft, rated prime for spring brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Secondary point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (1 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Secondary point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (1 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, lake trout run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 15 to 50 ft, and winter fish settle into 13 to 50 ft. Deep basin is the standout, a deep basin at roughly 50 ft, rated prime for summer lake trout. Time it for early morning. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
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 | 10 to 40 ft | dawn & dusk | Secondary point (8 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 15 to 50 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (50 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Secondary point (8 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 13 to 50 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (50 ft) | White tube jig, Airplane jig |
Spring cisco (lake herring) on Maquon Lake hold shallow, usually 10 to 40 ft. By summer they slide out to 15 to 50 ft, and by winter most fish are in 15 to 50 ft. The chart's best answer is Deep basin — deep basin, 50 ft, prime for summer. Prime time lands in early morning. The summer box starts with a vertical flutter spoon (small) or a drop-shot micro plastic.
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 | 10 to 40 ft | dawn & dusk | Deep basin (50 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 15 to 50 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (50 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (1 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 15 to 50 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (50 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
When the water first warms, walleye slide up into 4 to 15 ft. Summer is a 15 to 35 ft game here, winter a 20 to 40 ft one. Start at Secondary point. It's a point holding about 8 ft of water and rates prime come fall. The feeding windows run the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Secondary point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Shallow feeding flat (20 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Secondary point (8 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Deep basin (50 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 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.
| 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 | Shallow feeding flat (20 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Secondary point (8 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Secondary point (8 ft) | Tip-ups, Large jigging spoon |
In spring, burbot run shallow here, mostly 15 to 50 ft. Summer keeps them at 15 to 50 ft, and they winter in 13 to 50 ft. Deep basin is the standout, a deep basin at roughly 50 ft, rated prime for spring burbot. Time it for after dark and midday. You won't need more than a heavy jig + cut bait most summer days.
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 | 15 to 50 ft chart-limited; documented 25 to 70 ft | night & dusk | Deep basin (50 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 15 to 50 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (50 ft) | Heavy jig + cut bait |
| Fall | 15 to 50 ft chart-limited; documented 30 to 80 ft | night & dusk | Deep basin (50 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 13 to 50 ft chart-limited; documented 15 to 60 ft | night & dusk | Deep basin (50 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |

Maquon Lake is about 50 ft (15 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1966, a decades-old survey (a transect sounding survey).
Anglers target brook trout, lake trout, cisco (lake herring), walleye, northern pike, burbot on Maquon 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.
Deep basin is the top-rated area: a deep basin in about 50 ft of water that rates prime for lake trout in summer. Scroll up to the map for the complete spot list by species and season.
For brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
