Rating depth structure for crappie.

11-acre lake in Chippewa County, Wisconsin. The lake tops out around 6 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. What follows comes from the same scoring engine that paints the spots above.
On the chart, Rock Lake draws 11 acres inside 1.1 miles of shoreline. A development index of 2.3 means a maze of bays and points: far more casting targets than a round bowl of the same size. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Tip to tip the water measures near 0.3 mi with a 0.2-mi widest point. You'll find it in Chippewa County. Closest neighbour on DepthScout: Horseshoe Lake, 1 mi northeast of here.
Early season yellow perch use the shallows, holding in 2 to 6 ft. Even in summer they hold at 2 to 6 ft; winter keeps them in 2 to 6 ft. The chart's best answer is Deep basin — deep basin, 5 ft, prime for fall. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 6 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 6 ft | dawn | Deep basin (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 6 ft | midday | Deep basin (5 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 6 ft | midday & dawn | Deep basin (5 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, crappie run shallow here, mostly 2 to 6 ft. Summer keeps them at 2 to 6 ft, and they winter in 2 to 6 ft. Winter crappie concentrate at Deep basin, a prime-rated deep basin around 5 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a jig trolled/spider-rigged or a small crankbait (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 6 ft | midday & dawn | open water | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 2 to 6 ft | dawn & dusk | Deep basin (5 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 2 to 6 ft | dawn | Deep basin (5 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 2 to 6 ft | midday | Deep basin (5 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. They don't go far with the seasons — 2 to 6 ft covers summer, 2 to 6 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 5 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a small sponge spider (fly) or a micro tube jig until the fish tell you otherwise.
| 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 | 2 to 6 ft | dawn & dusk | open water | Small sponge spider (fly), Micro tube jig |
| Fall | 2 to 6 ft | midday | open water | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 6 ft | midday | Deep basin (5 ft) | Tungsten ice jig + plastic, Tiny spoon |

Rock Lake is about 6 ft (2 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 on Rock 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 5 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.
