33-acre lake in Waupaca County, Wisconsin. The lake tops out around 10 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
The outline encloses 33 acres, worked by 0.9 miles of shoreline. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Tip to tip the water measures near 0.3 mi with a 0.3-mi widest point. It sits in Waupaca County. If the bite dies, Long Lake is 0 mi to the east.
The spring pattern is a shallow one: yellow perch in 3 to 10 ft. The depth story barely changes: 3 to 10 ft through summer, 3 to 10 ft in winter. The spot to know is Back-bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. 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 10 ft | midday & dawn | Back-bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 10 ft | dawn | Deep basin (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 10 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 10 ft | midday & dawn | Deep basin (10 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. Through summer count on 3 to 10 ft; the winter hold is 3 to 10 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 2 ft that scores prime in spring. 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 | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 3 to 10 ft | dawn & dusk | Back-bay flat (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 3 to 10 ft | midday & dawn | Back-bay flat (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 3 to 10 ft | midday | Shoreline break (6 ft) | Blade bait, Jigging spoon |
When the water first warms, crappie slide up into 2 to 8 ft. Summer is a 3 to 10 ft game here, winter a 3 to 10 ft one. Start at Deep basin. It's a deep basin holding about 10 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 | Shallow bay flat (2 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 3 to 10 ft | dawn & dusk | Back-bay flat (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 3 to 10 ft | dawn | Back-bay flat (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 3 to 10 ft | midday | Deep basin (10 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 3 to 10 ft, then a winter hold in 3 to 10 ft. Start at Shallow bay flat. It's a weed flat holding about 2 ft of water and rates prime come spring. 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 | Shallow bay flat (2 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 3 to 10 ft | dawn & dusk | Back-bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 3 to 10 ft | midday | Back-bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 3 to 10 ft | midday | Deep basin (10 ft) | Tungsten ice jig + plastic, Tiny spoon |

Siemer Lake is about 10 ft (3 m) deep at its deepest point. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target yellow perch, largemouth bass, crappie, bluegill on Siemer 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.
Back-bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for yellow perch in spring. The map above holds the full rated-spot list for every 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.
