Rating depth structure for crappie.

8-acre lake in Sawyer County, Wisconsin. The lake tops out around 8 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Here's the year, species by species, as the scoring engine sees it.
Un Spring maps at 8 acres behind 1.1 miles of shoreline. That shoreline is heavily fingered (development index 2.8) — bays, points and pockets everywhere, which multiplies the fishable edge. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Figure 0.4 mi of water from one end to the other, 0.2 mi at the beam. It sits in Sawyer County. Its nearest charted neighbour, Hungry Lake, is 1 mi to the north.
Spring brook trout on Un Spring hold shallow, usually 1 to 8 ft. Depth-wise the year is flat: 2 to 8 ft in summer, 1 to 8 ft once it turns cold. The chart's best answer is Deep basin — deep basin, 7 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 2 to 8 ft | dawn & dusk | Deep basin (7 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 8 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 1 to 8 ft | dawn | Deep basin (7 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: yellow perch sit in 2 to 8 ft that time of year. They don't go far with the seasons — 2 to 8 ft covers summer, 2 to 8 ft covers winter. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 8 ft | dawn | Deep basin (7 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 8 ft | midday | Deep basin (7 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 8 ft | midday & dawn | Deep basin (7 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for crappie tight to the bank in 2 to 8 ft. Through summer count on 2 to 8 ft; the winter hold is 2 to 8 ft. If you only fish one area, make it Deep basin: a deep basin around 7 ft that scores prime in winter. Best bite is early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 2 to 8 ft | dawn & dusk | Shallow bay flat (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 2 to 8 ft | dawn | Shallow bay flat (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 2 to 8 ft | midday | Deep basin (7 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
When the water first warms, bluegill slide up into 1 to 6 ft. By summer they slide out to 2 to 8 ft, and by winter most fish are in 2 to 8 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a small sponge spider (fly) or a micro tube jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 2 to 8 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 2 to 8 ft | midday | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 8 ft | midday | Deep basin (7 ft) | Tungsten ice jig + plastic, Tiny spoon |
The spring pattern is a shallow one: pumpkinseed in 1 to 8 ft. The depth story barely changes: 2 to 8 ft through summer, 2 to 8 ft in winter. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for the evening and early morning. Summer baits: a micro tube or a sponge spider (fly) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 8 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 2 to 8 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 8 ft | dawn | Shallow bay flat (3 ft) | Tungsten ice jig + plastic, Tiny spoon |
3 pieces of structure are mapped here — Main-lake point, around 8 ft, is the deepest of them.
Season dates, license requirements, and size and bag limits for Wisconsin waters are set by the Wisconsin DNR — and special regulations can apply to Un Spring specifically, so confirm the current rules before you fish.

Un Spring is about 8 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 brook trout, yellow perch, crappie, bluegill, pumpkinseed on Un Spring. 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 brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Un Spring is regulated by the Wisconsin DNR. Check the official Wisconsin regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
