77-acre lake in Oconto County, Wisconsin. The lake tops out around 13 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 77 acres wrapped in 2.2 miles of bank. A middling shoreline index (1.8) gives it some bays to work without being a maze. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Figure 0.7 mi of water from one end to the other, 0.4 mi at the beam. Oconto County claims this one. Wescott Lake sits 1 mi south — the closest neighbouring chart.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 4 to 13 ft, wintering in 4 to 13 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 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 | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 13 ft | dawn | Deep basin (11 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 13 ft | midday | Deep basin (11 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 13 ft | midday & dawn | Deep basin (11 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring northern pike on Ucil Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 4 to 13 ft, and by winter most fish are in 4 to 13 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |

Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 4 to 13 ft, then a winter hold in 4 to 13 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. 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 | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |

| Winter | 4 to 13 ft | midday | Deep basin (11 ft) | Blade bait, Jigging spoon |
Spring crappie on Ucil Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 4 to 13 ft, and by winter most fish are in 4 to 13 ft. The chart's best answer is Deep basin — deep basin, 11 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).
