57-acre lake in Iowa County, Wisconsin. The lake tops out around 14 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Species by species, here's what the data says the year looks like.
Drawn out, this is 57 acres of water rimmed by 2.6 miles of bank. That shoreline is heavily fingered (development index 2.5) — bays, points and pockets everywhere, which multiplies the fishable edge. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Figure 0.9 mi of water from one end to the other, 0.3 mi at the beam. You'll find it in Iowa County. The nearest mapped water is Cox Hollow Lake, 10 mi to the northeast.
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 4 to 14 ft game here, winter a 4 to 14 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| 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 | 4 to 14 ft | dawn | Deep basin (12 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 14 ft | midday | Deep basin (12 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 14 ft | midday & dawn | Deep basin (12 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, smallmouth bass run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 4 to 14 ft before dropping to 4 to 14 ft for winter. Fall smallmouth bass concentrate at Main-lake point, a prime-rated point around 8 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |
| Summer | 4 to 14 ft | dawn & dusk | Break off the point (6 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 4 to 14 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 4 to 14 ft | midday | Break off the point (6 ft) | Blade bait, Hair jig |
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 4 to 14 ft; cold water stacks them in 4 to 14 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring largemouth bass. Plan around early morning and the evening in the warm months. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 4 to 14 ft | dawn & dusk | Break off the point (6 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 14 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 4 to 14 ft | midday | Break off the point (6 ft) | Blade bait, Jigging spoon |
In spring, crappie run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 4 to 14 ft before dropping to 4 to 14 ft for winter. Winter crappie concentrate at Deep basin, a prime-rated deep basin around 12 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a jig trolled/spider-rigged or a small crankbait (trolled) most summer days.
| 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 | 4 to 14 ft | dawn & dusk | Break off the point (6 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 4 to 14 ft | dawn | Break off the point (6 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 4 to 14 ft | midday | Deep basin (12 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Warm water sends them out to 4 to 14 ft; cold water stacks them in 4 to 14 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a small sponge spider (fly) or a micro tube jig until the fish tell you otherwise.
| 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 14 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 4 to 14 ft | midday | Break off the point (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 4 to 14 ft | midday | Deep basin (12 ft) | Tungsten ice jig + plastic, Tiny spoon |

Ludden Lake is about 14 ft (4 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, smallmouth bass, largemouth bass, crappie, bluegill on Ludden 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. 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.
Fishing on Ludden 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.
