Rating depth structure for crappie.

41-acre lake in Rusk County, Wisconsin. The lake tops out around 4 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 41 acres, worked by 1.4 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Call it 0.4 mi long by 0.4 mi wide at the broadest reach. Rusk County claims this one. Its nearest charted neighbour, Round Lake, is 1 mi to the southeast.
In spring, yellow perch run shallow here, mostly 1 to 4 ft. Summer keeps them at 1 to 4 ft, and they winter in 1 to 4 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 1 to 4 ft | dawn | Deep basin (3 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 1 to 4 ft | midday | Deep basin (3 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 1 to 4 ft | midday & dawn | Deep basin (3 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season crappie use the shallows, holding in 1 to 4 ft. Even in summer they hold at 1 to 4 ft; winter keeps them in 1 to 4 ft. Put Deep basin first on the milk run — a deep basin near 3 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a jig trolled/spider-rigged or a small crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 1 to 4 ft | dawn & dusk | Shallow bay flat (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 1 to 4 ft | dawn | Shallow bay flat (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 1 to 4 ft | midday | Deep basin (3 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Early season bluegill use the shallows, holding in 1 to 4 ft. Even in summer they hold at 1 to 4 ft; winter keeps them in 1 to 4 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning and the evening. Tie on a small sponge spider (fly) or a micro tube jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 1 to 4 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 1 to 4 ft | midday | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 1 to 4 ft | midday | Deep basin (3 ft) | Tungsten ice jig + plastic, Tiny spoon |
In spring, pumpkinseed run shallow here, mostly 1 to 4 ft. Summer keeps them at 1 to 4 ft, and they winter in 1 to 4 ft. Spring pumpkinseed concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a micro tube or a sponge spider (fly) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 1 to 4 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 1 to 4 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 1 to 4 ft | dawn | Shallow bay flat (3 ft) | Tungsten ice jig + plastic, Tiny spoon |

Bull Moose Lake is about 4 ft (1 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 Bull Moose 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.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for yellow perch in spring. The map above holds the full rated-spot list for every 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.
