15-acre lake in Marinette County, Wisconsin. The lake tops out around 9 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. What the data behind the map says about each species, season by season:
The outline encloses 15 acres, worked by 0.6 miles of shoreline. Nearly circular (index 1), so the story is the bottom, not the bank. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Marinette County claims this one. If the bite dies, Nadjak Lake is 1 mi to the east.
In spring, yellow perch run shallow here, mostly 2 to 9 ft. Summer keeps them at 3 to 9 ft, and they winter in 3 to 9 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 9 ft | dawn | Deep basin (8 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 9 ft | midday | Deep basin (8 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 9 ft | midday & dawn | Deep basin (8 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season crappie use the shallows, holding in 2 to 8 ft. Expect a summer slide to 3 to 9 ft, then a winter hold in 3 to 9 ft. Put Deep basin first on the milk run — a deep basin near 8 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a jig trolled/spider-rigged or a small crankbait (trolled) and you're in the game.
| 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 | 3 to 9 ft | dawn & dusk | Shallow bay flat (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 3 to 9 ft | dawn | Shallow bay flat (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 3 to 9 ft | midday | Deep basin (8 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Early season bluegill use the shallows, holding in 1 to 6 ft. Summer is a 2 to 9 ft game here, winter a 3 to 9 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning and the evening. Tie on a small sponge spider (fly) or a micro tube jig and you're in the game.
| 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 | 2 to 9 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 3 to 9 ft | midday | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 3 to 9 ft | midday | Deep basin (8 ft) | Tungsten ice jig + plastic, Tiny spoon |
In spring, pumpkinseed run shallow here, mostly 1 to 8 ft. Midsummer fish sit out in 2 to 9 ft before dropping to 3 to 9 ft for winter. Spring pumpkinseed concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a micro tube or a sponge spider (fly) most summer days.
| 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 9 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 3 to 9 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 3 to 9 ft | dawn | Shallow bay flat (3 ft) | Tungsten ice jig + plastic, Tiny spoon |

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 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.
