28-acre lake in Columbia County, Wisconsin. The lake tops out around 4 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. What the data behind the map says about each species, season by season:
On the chart, Corning Lake draws 28 acres inside 1.3 miles of shoreline. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Tip to tip the water measures near 0.3 mi with a 0.3-mi widest point. You'll find it in Columbia County. For a second option, Weeting Lake lies 1 mi northeast.
Come spring, look for yellow perch tight to the bank in 1 to 4 ft. Through summer count on 1 to 4 ft; the winter hold is 1 to 4 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 1 to 4 ft | dawn | Deep basin (3 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 1 to 4 ft | midday | Deep basin (3 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 1 to 4 ft | midday & dawn | Deep basin (3 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: largemouth bass in 1 to 4 ft. The depth story barely changes: 1 to 4 ft through summer, 1 to 4 ft in winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for largemouth bass in spring. Plan around early morning and the evening in the warm months. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 1 to 4 ft | dawn & dusk | Shallow bay flat (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 1 to 4 ft | midday & dawn | Main-lake point (4 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 1 to 4 ft | midday | Break off the point (2 ft) | Blade bait, Jigging spoon |
Start shallow in spring: crappie sit in 1 to 4 ft that time of year. They don't go far with the seasons — 1 to 4 ft covers summer, 1 to 4 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 3 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a jig trolled/spider-rigged or a small crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 1 to 4 ft | dawn & dusk | Shallow bay flat (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 1 to 4 ft | dawn | Shallow bay flat (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 1 to 4 ft | midday | Deep basin (3 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
In spring, bluegill run shallow here, mostly 1 to 4 ft. Summer keeps them at 1 to 4 ft, and they winter in 1 to 4 ft. Spring bluegill concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small sponge spider (fly) or a micro tube jig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 1 to 4 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 1 to 4 ft | midday | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 1 to 4 ft | midday | Deep basin (3 ft) | Tungsten ice jig + plastic, Tiny spoon |

Corning Lake is about 4 ft (1 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 on Corning 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. Every other rated spot, per species and season, is on the map above.
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.
Fishing on Corning 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.
