13-acre lake in Taylor County, Wisconsin. The lake tops out around 18 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. What the data behind the map says about each species, season by season:
The outline encloses 13 acres, worked by 0.6 miles of shoreline. Nearly circular (index 1.2), so the story is the bottom, not the bank. The shallow band under 15 ft claims about 68% of the surface on the model — that's where the groceries are. Taylor County claims this one. Its nearest charted neighbour, Kathryn Lake, is 1 mi to the south.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 5 to 18 ft, wintering in 5 to 18 ft. Fall yellow perch concentrate at Deep basin, a prime-rated deep basin around 15 ft. Warm-month bites cluster around early morning. 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 | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 18 ft | dawn | Deep basin (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 18 ft | midday | Deep basin (15 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 18 ft | midday & dawn | Deep basin (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring crappie on Foss Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 5 to 18 ft, and by winter most fish are in 5 to 18 ft. The chart's best answer is Deep basin — deep basin, 15 ft, prime for winter. Prime time lands in 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 8 ft | midday & dawn | open water | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 5 to 18 ft | dawn & dusk | Break off the point (8 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 5 to 18 ft | dawn | Break off the point (8 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 5 to 18 ft | midday | Deep basin (15 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring bluegill on Foss Lake hold shallow, usually 1 to 6 ft. They move out to 4 to 15 ft in summer and finish the year down in 5 to 18 ft. Put Deep basin first on the milk run — a deep basin near 15 ft that grades prime for winter. The feeding windows run early morning and the evening. 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 | 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 (8 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 18 ft | midday | Deep basin (15 ft) | Tungsten ice jig + plastic, Tiny spoon |

Deep basin is the top-rated area: a deep basin in about 15 ft of water that rates prime for yellow perch in fall. Every other rated spot, per species and season, is on the map above.
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.
