118-acre lake in Langlade County, Wisconsin. The lake tops out around 19 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. The season-by-season read for each species follows, from the map's own numbers.
Duck Lake maps at 118 acres behind 2.1 miles of shoreline. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 84% of this chart, as modeled. Figure 0.7 mi of water from one end to the other, 0.5 mi at the beam. Langlade County claims this one. Its nearest charted neighbour, Airhole Lake, is 1 mi to the north.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 6 to 19 ft, wintering in 6 to 19 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 19 ft | dawn | Deep basin (16 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 19 ft | midday | Deep basin (16 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 19 ft | midday & dawn | Deep basin (16 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring northern pike on Duck Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 6 to 19 ft, and by winter most fish are in 5 to 15 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |

Spring muskellunge on Duck Lake hold shallow, usually 3 to 12 ft. They move out to 6 to 19 ft in summer and finish the year down in 6 to 19 ft. Put Break off the point first on the milk run — a drop-off near 9 ft that grades prime for fall. The feeding windows run the evening and early morning. The summer box starts with a double-10 bucktail or a topwater (walk-the-dog / creeper).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (3 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 6 to 19 ft | dusk & dawn | Main-lake point (8 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 5 to 19 ft | midday & dusk | Break off the point (9 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 6 to 19 ft | midday | Deep basin (16 ft) | Large rubber, crawled slow |
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 6 to 19 ft, then a winter hold in 6 to 19 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |

Spring bluegill on Duck Lake hold shallow, usually 1 to 6 ft. They move out to 4 to 15 ft in summer and finish the year down in 6 to 19 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a small sponge spider (fly) or a micro tube jig.

Duck Lake is about 19 ft (6 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target yellow perch, northern pike, muskellunge, largemouth bass, crappie, bluegill, pumpkinseed on Duck Lake. These come from the Wisconsin DNR's per-lake fish listing; where the DNR lists a group (panfish, catfish, trout) the specific species are resolved from Wisconsin's fish distribution by the lake's location, depth and habitat.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Scroll up to the map for the complete spot list by species and season.
For yellow perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
