13-acre lake in Vilas County, Wisconsin. The lake tops out around 22 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 13 acres of water rimmed by 0.6 miles of bank. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. About 44% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. You'll find it in Vilas County. Closest neighbour on DepthScout: Secret Lake, 1 mi south of here.
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 7 to 22 ft game here, winter a 7 to 22 ft one. The chart's best answer is Deep basin — deep basin, 19 ft, prime for fall. 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 | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 7 to 22 ft | dawn | Deep basin (19 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 7 to 22 ft | midday | Deep basin (19 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 7 to 22 ft | midday & dawn | Deep basin (19 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 7 to 22 ft. Main-lake point is the standout, a point at roughly 8 ft, rated prime for fall 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 | Main-lake point (8 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (10 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 | 7 to 22 ft | midday | Break off the point (10 ft) | Blade bait, Jigging spoon |
In spring, crappie run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 7 to 22 ft before dropping to 7 to 22 ft for winter. Winter crappie concentrate at Deep basin, a prime-rated deep basin around 19 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 | open water | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 7 to 22 ft | dawn & dusk | Break off the point (10 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Break off the point (10 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 7 to 22 ft | midday | Deep basin (19 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 15 ft; cold water stacks them in 7 to 22 ft. Top water on the chart: Deep basin, a deep basin in the 19 ft range, prime in winter. 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 | open water | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | open water | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (10 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 7 to 22 ft | midday | Deep basin (19 ft) | Tungsten ice jig + plastic, Tiny spoon |
Come spring, look for pumpkinseed tight to the bank in 1 to 8 ft. They move out to 2 to 10 ft in summer and finish the year down in 6 to 18 ft. If you only fish one area, make it Deep basin: a deep basin around 19 ft that scores prime in winter. Best bite is the evening and early morning. A micro tube or a sponge spider (fly) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | open water | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | open water | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Break off the point (10 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Deep basin (19 ft) | Tungsten ice jig + plastic, Tiny spoon |

Plymouth Lake is about 22 ft (7 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 Plymouth 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.
Deep basin is the top-rated area: a deep basin in about 19 ft of water that rates prime for yellow perch in fall. The interactive chart above rates every spot for each 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 Plymouth 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.
