Rating depth structure for crappie.

7-acre lake in Florence County, Wisconsin. The lake tops out around 17 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. What follows comes from the same scoring engine that paints the spots above.
On the chart, Olson Lake draws 7 acres inside 0.4 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. About 57% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The water lies in Florence County. For a second option, Bass Lake lies 1 mi west.
Spring yellow perch on Olson Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 5 to 17 ft, and by winter most fish are in 5 to 17 ft. The chart's best answer is Deep basin — deep basin, 14 ft, prime for fall. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| 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 17 ft | dawn | Deep basin (14 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 17 ft | midday | Deep basin (14 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 17 ft | midday & dawn | Deep basin (14 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts crappie in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 5 to 17 ft, wintering in 5 to 17 ft. Winter crappie concentrate at Deep basin, a prime-rated deep basin around 14 ft. Warm-month bites cluster around early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) covers the summer program.
| 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 17 ft | dawn & dusk | Break off the point (8 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 5 to 17 ft | dawn | Break off the point (8 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 5 to 17 ft | midday | Deep basin (14 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
The spring pattern is a shallow one: bluegill in 1 to 6 ft. As the season builds they drop to 4 to 15 ft, wintering in 5 to 17 ft. Top water on the chart: Deep basin, a deep basin in the 14 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a small sponge spider (fly) or a micro tube jig gets it done.
| 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 17 ft | midday | Break off the point (8 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 17 ft | midday | Deep basin (14 ft) | Tungsten ice jig + plastic, Tiny spoon |
When the water first warms, pumpkinseed slide up into 1 to 8 ft. By summer they slide out to 2 to 10 ft, and by winter most fish are in 5 to 17 ft. If you only fish one area, make it Deep basin: a deep basin around 14 ft that scores prime in winter. In summer the feeding windows fall in the evening and early morning. Keep a micro tube or a sponge spider (fly) rigged through the warm months.
| 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 (8 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 17 ft | dawn | Deep basin (14 ft) | Tungsten ice jig + plastic, Tiny spoon |

Olson Lake is about 17 ft (5 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target yellow perch, crappie, bluegill, pumpkinseed on Olson Lake. These come from the Wisconsin DNR's per-lake fish listing; where the DNR lists a group (panfish, catfish, trout) the specific species are resolved from Wisconsin's fish distribution by the lake's location, depth and habitat.
Deep basin is the top-rated area: a deep basin in about 14 ft of water that rates prime for yellow perch in fall. Scroll up to the map for the complete spot list by species and season.
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.
