25-acre lake in Vilas County, Wisconsin. The lake tops out around 26 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Korth Lake runs 25 acres with 1 miles of edge. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 49% of this chart, as modeled. The basin spans about 0.4 mi end to end and 0.2 mi across at its widest. You'll find it in Vilas County. For a second option, Squash Lake lies 1 mi northeast.
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 8 to 26 ft in summer and finish the year down in 8 to 26 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 | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 26 ft | dawn | Deep basin (22 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 26 ft | midday | Deep basin (22 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 26 ft | midday & dawn | Deep basin (22 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 8 to 26 ft for 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 | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (12 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 | 8 to 26 ft | midday | Break off the point (12 ft) | Blade bait, Jigging spoon |
Start shallow in spring: crappie sit in 2 to 8 ft that time of year. Warm water sends them out to 10 to 25 ft; cold water stacks them in 8 to 26 ft. Top water on the chart: Deep basin, a deep basin in the 22 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 | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Break off the point (12 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Break off the point (12 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 8 to 26 ft | midday | Deep basin (22 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
In spring, bluegill run shallow here, mostly 1 to 6 ft. Midsummer fish sit out in 4 to 15 ft before dropping to 10 to 25 ft for winter. 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 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 | Break off the point (12 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (22 ft) | Tungsten ice jig + plastic, Tiny spoon |
Early season pumpkinseed use the shallows, holding in 1 to 8 ft. Summer is a 2 to 10 ft game here, winter a 6 to 18 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is the evening and early morning. Tie on a micro tube or a sponge spider (fly) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (3 ft) | Tungsten ice jig + plastic, Tiny spoon |

Korth Lake is about 26 ft (8 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 Korth 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.
