264-acre lake in Burnett County, Wisconsin. The lake tops out around 34 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Species by species, here's what the data says the year looks like.
Viola Lake maps at 264 acres behind 3.6 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 73% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 1.1 mi with a 0.7-mi widest point. Burnett County claims this one. Its nearest charted neighbour, Rohr Lake, is 1 mi to the south.
Spring puts walleye in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 10 to 34 ft, wintering in 10 to 34 ft. Winter walleye concentrate at Deep basin, a prime-rated deep basin around 29 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (9 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 10 to 34 ft | dusk & dawn | Main-lake point (9 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 10 to 34 ft | dusk & night | Main-lake point (9 ft) | Jigging rap, Jig + big minnow |
| Winter | 10 to 34 ft | dusk & dawn | Deep basin (29 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 10 to 34 ft. The spot to know is Shallow bay flat, a weed flat in about 4 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. 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 | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (29 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 10 to 34 ft | midday | Deep basin (29 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 10 to 34 ft | midday & dawn | Deep basin (29 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Start at Shallow bay flat. It's a weed flat holding about 4 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage 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 (4 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (9 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (9 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (4 ft) | Tip-ups, Large jigging spoon |
When the water first warms, largemouth bass slide up into 2 to 10 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 10 to 34 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 4 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (4 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (9 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (9 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 10 to 34 ft | midday | Deep basin (29 ft) | Blade bait, Jigging spoon |
Come spring, look for crappie tight to the bank in 2 to 8 ft. Expect a summer slide to 10 to 25 ft, then a winter hold in 10 to 34 ft. Start at Deep basin. It's a deep basin holding about 29 ft of water and rates prime come winter. Prime time lands in 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 (4 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Deep basin (29 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Shallow bay flat (4 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 10 to 34 ft | midday | Deep basin (29 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
When the water first warms, bluegill slide up into 1 to 6 ft. Summer is a 4 to 15 ft game here, winter a 10 to 25 ft one. Start at Shallow bay flat. It's a weed flat holding about 4 ft of water and rates prime come spring. The feeding windows run 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 (4 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (4 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (29 ft) | Tungsten ice jig + plastic, Tiny spoon |

Viola Lake is about 34 ft (10 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 walleye, yellow perch, northern pike, largemouth bass, crappie, bluegill, pumpkinseed on Viola 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 29 ft of water that rates prime for walleye in winter. The map above holds the full rated-spot list for every species and season.
For walleye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
