25-acre lake in Marathon County, Wisconsin. The lake tops out around 6 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Here is how the season plays out for each species, straight from the data behind the map.
Little Frog Lake maps at 25 acres behind 0.9 miles of shoreline. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. End to end it runs roughly 0.3 mi, about 0.2 mi across. It sits in Marathon County. Its nearest charted neighbour, Mission Lake, is 1 mi to the northeast.
Spring puts yellow perch in skinny water — 2 to 6 ft is the zone. Summer fish stay in 2 to 6 ft, and winter fish hold in 2 to 6 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 6 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 6 ft | dawn | Deep basin (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 6 ft | midday | Deep basin (5 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 6 ft | midday & dawn | Deep basin (5 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring crappie on Little Frog Lake hold shallow, usually 2 to 6 ft. Depth-wise the year is flat: 2 to 6 ft in summer, 2 to 6 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 5 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a jig trolled/spider-rigged or a small crankbait (trolled).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 6 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 2 to 6 ft | dawn & dusk | Shallow bay flat (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 2 to 6 ft | dawn | Shallow bay flat (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |

The summer box starts with a small sponge spider (fly) or a micro tube jig.
| 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 6 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 2 to 6 ft | midday | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 6 ft | midday | Deep basin (5 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.
