34-acre lake in Oconto County, Wisconsin. The lake tops out around 19 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Species by species, here's what the data says the year looks like.
Ledge Lake maps at 34 acres behind 0.9 miles of shoreline. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. About 65% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. End to end it runs roughly 0.3 mi, about 0.2 mi across. Oconto County claims this one. If the bite dies, Wonder Lake is 1 mi to the east.
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 6 to 19 ft, and winter fish settle into 6 to 19 ft. 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 | 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) |
Come spring, look for crappie tight to the bank in 2 to 8 ft. Expect a summer slide to 6 to 19 ft, then a winter hold in 6 to 19 ft. Start at Deep basin. It's a deep basin holding about 16 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 6 to 19 ft | dawn & dusk | Shoreline break (9 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 6 to 19 ft | dawn | Shoreline break (9 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 6 to 19 ft | midday | Deep basin (16 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
When the water first warms, bluegill slide up into 1 to 6 ft. Summer is a 4 to 15 ft game here, winter a 6 to 19 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a small sponge spider (fly) or a micro tube jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shoreline break (9 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 19 ft | midday | Deep basin (16 ft) | Tungsten ice jig + plastic, Tiny spoon |

Ledge 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, crappie, bluegill on Ledge 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.
