15-acre lake in Langlade County, Wisconsin. The lake tops out around 21 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Indian Lake runs 15 acres with 0.8 miles of edge. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. Roughly 61% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 0.3 mi. The water lies in Langlade County. The nearest mapped water is East Lake, 0 mi to the east.
When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 6 to 21 ft, and by winter most fish are in 6 to 21 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 8 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (8 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 21 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 21 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 21 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 6 to 21 ft. The spot to know is Shallow bay flat, a weed flat in about 8 ft of water that rates prime for largemouth bass in spring. Warm-month bites cluster around early morning and the evening. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (8 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (8 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 6 to 21 ft | midday | Shoreline break (10 ft) | Blade bait, Jigging spoon |
The spring pattern is a shallow one: crappie in 2 to 8 ft. As the season builds they drop to 6 to 21 ft, wintering in 6 to 21 ft. Top water on the chart: Deep basin, a deep basin in the 20 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a jig trolled/spider-rigged or a small crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (8 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 6 to 21 ft | dawn & dusk | Shallow bay flat (8 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Shallow bay flat (8 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 6 to 21 ft | midday | Deep basin (20 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring puts bluegill in skinny water — 1 to 6 ft is the zone. As the season builds they drop to 4 to 15 ft, wintering in 6 to 21 ft. Spring bluegill concentrate at Back-bay flat, a prime-rated weed flat around 2 ft. Warm-month bites cluster around early morning and the evening. A small sponge spider (fly) or a micro tube jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Back-bay flat (2 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (8 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (8 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 21 ft | midday | Deep basin (20 ft) | Tungsten ice jig + plastic, Tiny spoon |
Spring pumpkinseed on Indian Lake hold shallow, usually 1 to 8 ft. By summer they slide out to 2 to 10 ft, and by winter most fish are in 6 to 18 ft.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (8 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (8 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (8 ft) | Micro jig + waxworm, Small spoon tipped |

Indian Lake is about 21 ft (6 m) deep at its deepest point. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target yellow perch, largemouth bass, crappie, bluegill, pumpkinseed on Indian 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 8 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.
Fishing on Indian Lake 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.
