Rating depth structure for largemouth bass.

8-acre lake in Oneida County, Wisconsin. The lake tops out around 15 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 follows comes from the same scoring engine that paints the spots above.
The outline encloses 8 acres, worked by 0.4 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. Oneida County claims this one. If the bite dies, Timber 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 5 to 15 ft, wintering in 5 to 15 ft. Fall yellow perch concentrate at Deep basin, a prime-rated deep basin around 13 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 15 ft | dawn | Deep basin (13 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 15 ft | midday | Deep basin (13 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 15 ft | midday & dawn | Deep basin (13 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 5 to 15 ft, then a winter hold in 5 to 15 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 | 5 to 15 ft | dawn & dusk | Break off the point (7 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 | 5 to 15 ft | midday | Break off the point (7 ft) | Blade bait, Jigging spoon |
Spring crappie on Spruce Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 5 to 15 ft, and by winter most fish are in 5 to 15 ft. The chart's best answer is Deep basin — deep basin, 13 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 15 ft | dawn & dusk | Break off the point (7 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 5 to 15 ft | dawn | Break off the point (7 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 5 to 15 ft | midday | Deep basin (13 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring bluegill on Spruce 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 15 ft. Put Deep basin first on the milk run — a deep basin near 13 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 | 5 to 15 ft | midday | Break off the point (7 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 15 ft | midday | Deep basin (13 ft) | Tungsten ice jig + plastic, Tiny spoon |
Spring puts pumpkinseed in skinny water — 1 to 8 ft is the zone. Warm water sends them out to 2 to 10 ft; cold water stacks them in 5 to 15 ft. Deep basin is the standout, a deep basin at roughly 13 ft, rated prime for winter pumpkinseed. Plan around the evening and early morning in the warm months. A micro tube or a sponge spider (fly) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | open water | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | open water | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Break off the point (7 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 15 ft | dawn | Deep basin (13 ft) | Tungsten ice jig + plastic, Tiny spoon |
