6-acre lake in Waupaca County, Wisconsin. The lake tops out around 25 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. What follows comes from the same scoring engine that paints the spots above.
The drawn water covers 6 acres wrapped in 0.5 miles of bank. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. About 38% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Waupaca County claims this one. Its nearest charted neighbour, School Section Lake, is 1 mi to the northeast.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 8 to 25 ft, wintering in 8 to 25 ft. Fall yellow perch concentrate at Deep basin, a prime-rated deep basin around 21 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 | 8 to 25 ft | dawn | Deep basin (21 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 25 ft | midday | Deep basin (21 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 25 ft | midday & dawn | Deep basin (21 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 8 to 25 ft. Put Main-lake point first on the milk run — a point near 8 ft that grades prime for fall. In summer the feeding windows fall in early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
| 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 (11 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 | 8 to 25 ft | midday | Break off the point (11 ft) | Blade bait, Jigging spoon |
Spring crappie on Chapin Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 10 to 25 ft, and by winter most fish are in 8 to 25 ft. The chart's best answer is Deep basin — deep basin, 21 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 | 10 to 25 ft | dawn & dusk | Break off the point (11 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Break off the point (11 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 8 to 25 ft | midday | Deep basin (21 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring bluegill on Chapin Lake hold shallow, usually 1 to 6 ft. They move out to 4 to 15 ft in summer and finish the year down in 10 to 25 ft. Put Deep basin first on the milk run — a deep basin near 21 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 (11 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (21 ft) | Tungsten ice jig + plastic, Tiny spoon |
