Rating depth structure for largemouth bass.

10-acre lake in Langlade County, Wisconsin. The lake tops out around 14 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Sunfish Lake draws 10 acres inside 0.6 miles of shoreline. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. The water lies in Langlade County. Closest neighbour on DepthScout: Lower Bass Lake, 1 mi north of here.
Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 4 to 14 ft, then a winter hold in 4 to 14 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in 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 | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 14 ft | dawn | Deep basin (12 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 14 ft | midday | Deep basin (12 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 14 ft | midday & dawn | Deep basin (12 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 4 to 14 ft, wintering in 4 to 14 ft. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 4 to 14 ft | dawn & dusk | Shoreline break (6 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 14 ft | midday & dawn | Shallow bay flat (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 4 to 14 ft | midday | Shoreline break (6 ft) | Blade bait, Jigging spoon |
In spring, crappie run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 4 to 14 ft, and winter fish settle into 4 to 14 ft. Deep basin is the standout, a deep basin at roughly 12 ft, rated prime for winter crappie. Time it for early morning and the evening. 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 8 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 4 to 14 ft | dawn & dusk | Shoreline break (6 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 4 to 14 ft | dawn | Shoreline break (6 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 4 to 14 ft | midday | Deep basin (12 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Summer pushes them deeper, 4 to 14 ft, and winter fish settle into 4 to 14 ft. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for bluegill in spring. Warm-month bites cluster around early morning and the evening. 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 | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 14 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 4 to 14 ft | midday | Shoreline break (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 4 to 14 ft | midday | Deep basin (12 ft) | Tungsten ice jig + plastic, Tiny spoon |

Sunfish Lake is about 14 ft (4 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, largemouth bass, crappie, bluegill on Sunfish 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 interactive chart above rates every spot for each 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.
