6-acre lake in Oneida County, Wisconsin. The lake tops out around 31 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. What the data behind the map says about each species, season by season:
The outline encloses 6 acres, worked by 0.4 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. About 33% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. It sits in Oneida County. If the bite dies, Myrtle Lake is 0 mi to the west.
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 9 to 31 ft for winter. The spot to know is Deep basin, a deep basin in about 26 ft of water that rates prime for yellow perch in fall. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (26 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 31 ft | midday | Deep basin (26 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 9 to 31 ft | midday & dawn | Deep basin (26 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 9 to 31 ft. If you only fish one area, make it Main-lake point: a point around 8 ft that scores prime in fall. Best bite is early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Main-lake point (8 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (14 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 9 to 31 ft | midday | Break off the point (14 ft) | Blade bait, Jigging spoon |
When the water first warms, crappie slide up into 2 to 8 ft. Summer is a 10 to 25 ft game here, winter a 9 to 31 ft one. Start at Deep basin. It's a deep basin holding about 26 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a jig trolled/spider-rigged or a small crankbait (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | open water | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Break off the point (14 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Break off the point (14 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 9 to 31 ft | midday | Deep basin (26 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Come spring, look for bluegill tight to the bank in 1 to 6 ft. Expect a summer slide to 4 to 15 ft, then a winter hold in 10 to 25 ft. Start at Deep basin. It's a deep basin holding about 26 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A small sponge spider (fly) or a micro tube jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | open water | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | open water | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (14 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (26 ft) | Tungsten ice jig + plastic, Tiny spoon |
Start shallow in spring: pumpkinseed sit in 1 to 8 ft that time of year. Summer pushes them deeper, 2 to 10 ft, and winter fish settle into 6 to 18 ft. The spot to know is Break off the point, a drop-off in about 14 ft of water that rates good for pumpkinseed in fall. Warm-month bites cluster around the evening and early morning. Throw a micro tube or a sponge spider (fly) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | open water | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | open water | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Break off the point (14 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Break off the point (14 ft) | Tungsten ice jig + plastic, Tiny spoon |

Swartz Lake is about 31 ft (9 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, largemouth bass, crappie, bluegill, pumpkinseed on Swartz 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.
Deep basin is the top-rated area: a deep basin in about 26 ft of water that rates prime for yellow perch in fall. Open the map above to see every rated spot for each 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.
