294-acre lake in Oneida County, Wisconsin. The lake tops out around 8 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Swamp Lake draws 294 acres inside 3.3 miles of shoreline. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. End to end it runs roughly 1.1 mi, about 0.7 mi across. The water lies in Oneida County. Closest neighbour on DepthScout: Prairie Lake, 3 mi southeast of here.
Early season walleye use the shallows, holding in 2 to 8 ft. Even in summer they hold at 2 to 8 ft; winter keeps them in 2 to 8 ft. The chart's best answer is Break off the point — drop-off, 4 ft, prime for fall. 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 | 2 to 8 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 2 to 8 ft | dusk & dawn | Break off the point (4 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 2 to 8 ft | dusk & night | Break off the point (4 ft) | Jigging rap, Jig + big minnow |
| Winter | 2 to 8 ft | dusk & dawn | Deep basin (7 ft) | Jigging spoon + minnow head, Rattle bait |
Spring yellow perch on Swamp Lake hold shallow, usually 2 to 8 ft. Depth-wise the year is flat: 2 to 8 ft in summer, 2 to 8 ft once it turns cold. The chart's best answer is Shallow bay flat — weed flat, 3 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 | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 8 ft | dawn | Deep basin (7 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Summer fish stay in 2 to 8 ft, and winter fish hold in 2 to 8 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 3 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 | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |

| Winter | 2 to 8 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
In spring, largemouth bass run shallow here, mostly 2 to 8 ft. Summer keeps them at 2 to 8 ft, and they winter in 2 to 8 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 2 to 8 ft | dawn & dusk | Shallow bay flat (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 2 to 8 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |

Winter crappie concentrate at Deep basin, a prime-rated deep basin around 7 ft. Warm-month bites cluster around early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) covers the summer program.

Swamp Lake is about 8 ft (2 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 walleye, yellow perch, northern pike, largemouth bass, crappie, bluegill, pumpkinseed on Swamp 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.
Break off the point is the top-rated area: a drop-off in about 4 ft of water that rates prime for walleye in fall. The interactive chart above rates every 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.
Fishing on Swamp Lake is regulated by the Wisconsin DNR. Check the official Wisconsin regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
