179-acre lake in Kenora District, Ontario. The lake tops out around 7 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 1979, a decades-old survey (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
Duck L. maps at 179 acres behind 6.4 miles of shoreline — 2 islands included. A development index of 3.4 means a maze of bays and points: far more casting targets than a round bowl of the same size. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. End to end it runs roughly 1 mi, about 0.8 mi across. Kenora District claims this one. Columbus L. sits 1 mi east — the closest neighbouring chart.
Spring puts walleye in skinny water — 2 to 7 ft is the zone. Summer fish stay in 2 to 7 ft, and winter fish hold in 2 to 7 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 3 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
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 | 2 to 7 ft chart-limited; documented 4 to 15 ft | dusk & dawn | Main-lake point (7 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 2 to 7 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (3 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 2 to 7 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (3 ft) | Jigging rap, Jig + big minnow |
| Winter | 2 to 7 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (7 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, sauger run shallow here, mostly 2 to 7 ft. Summer keeps them at 2 to 7 ft, and they winter in 2 to 7 ft. Winter sauger concentrate at Deep basin, a prime-rated deep basin around 7 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bottom bouncer + crawler or a 3-way rig with stickbait most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft chart-limited; documented 4 to 18 ft | dawn & dusk | Main-lake point (7 ft) | 3/8 oz jig + ringworm, Hair jig + minnow |
| Summer | 2 to 7 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Break off the point (3 ft) | Bottom bouncer + crawler, 3-way rig with stickbait |
| Fall | 2 to 7 ft chart-limited; documented 12 to 35 ft | dusk & dawn | Break off the point (3 ft) | Jig + big minnow, Blade bait |
| Winter | 2 to 7 ft chart-limited; documented 15 to 45 ft | dusk | Deep basin (7 ft) | Heavy jigging spoon, Jig + minnow (vertical) |
Start shallow in spring: yellow perch sit in 2 to 7 ft that time of year. They don't go far with the seasons — 2 to 7 ft covers summer, 2 to 7 ft covers winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 7 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (7 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 7 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (7 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 7 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (7 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 7 ft. Through summer count on 2 to 7 ft; the winter hold is 2 to 7 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft chart-limited; documented 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 7 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 7 ft chart-limited; documented 6 to 18 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 2 to 7 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Come spring, look for smallmouth bass tight to the bank in 2 to 7 ft. Through summer count on 2 to 7 ft; the winter hold is 2 to 7 ft. Start at Main-lake point. It's a point holding about 7 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.

6 pieces of structure are mapped here — Deep basin, around 7 ft, is the deepest of them.
Season dates, license requirements, and size and bag limits for Ontario waters are set by the Ontario fishing regulations (FMZ summary) — and special regulations can apply to Duck L. specifically, so confirm the current rules before you fish.

Duck L. is about 7 ft (2 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1979, a decades-old survey (a transect sounding survey).
Anglers target walleye, sauger, yellow perch, northern pike, smallmouth bass on Duck L.. 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 3 ft of water that rates prime for walleye in fall. Open the map above to see every rated 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.
