172-acre lake in Vilas County, Wisconsin. The lake tops out around 25 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Species by species, here's what the data says the year looks like.
On the chart, Round Lake draws 172 acres inside 2.2 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. 74% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 0.8 mi, about 0.6 mi across. You'll find it in Vilas County. For a second option, Little Crab Lake lies 1 mi north.
When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 8 to 25 ft, and by winter most fish are in 8 to 25 ft. If you only fish one area, make it Break off the point: a drop-off around 11 ft that scores prime in fall. In summer the feeding windows fall in the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 8 to 25 ft | dusk & dawn | Break off the point (11 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 8 to 25 ft | dusk & night | Break off the point (11 ft) | Jigging rap, Jig + big minnow |
| Winter | 8 to 25 ft | dusk & dawn | Deep basin (21 ft) | Jigging spoon + minnow head, Rattle bait |
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is an 8 to 25 ft game here, winter an 8 to 25 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run 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 (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 25 ft | dawn | Deep basin (21 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 25 ft | midday | Deep basin (21 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 25 ft | midday & dawn | Deep basin (21 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts muskellunge in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 8 to 25 ft; cold water stacks them in 8 to 25 ft. Break off the point is the standout, a drop-off at roughly 11 ft, rated prime for fall muskellunge. Plan around the evening and early morning in the warm months. A double-10 bucktail or a topwater (walk-the-dog / creeper) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (3 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 8 to 25 ft | dusk & dawn | Main-lake point (8 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 7 to 25 ft | midday & dusk | Break off the point (11 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 8 to 25 ft | midday | Deep basin (21 ft) | Large rubber, crawled slow |
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 8 to 25 ft. 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 the evening and you'll meet the bite. 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 (3 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (11 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 8 to 25 ft | midday | Break off the point (11 ft) | Blade bait, Jigging spoon |
The spring pattern is a shallow one: crappie in 2 to 8 ft. Midsummer fish sit out in 10 to 25 ft before dropping to 8 to 25 ft for winter. The spot to know is Deep basin, a deep basin in about 21 ft of water that rates prime for crappie in winter. Plan around early morning and the evening in the warm months. 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 (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Break off the point (11 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Break off the point (11 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 8 to 25 ft | midday | Deep basin (21 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring puts bluegill in skinny water — 1 to 6 ft is the zone. Warm water sends them out to 4 to 15 ft; cold water stacks them in 10 to 25 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring bluegill. Plan around early morning and the evening in the warm months. 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 | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |

| Winter | 10 to 25 ft | midday | Deep basin (21 ft) | Tungsten ice jig + plastic, Tiny spoon |

Round Lake is about 25 ft (8 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, muskellunge, largemouth bass, crappie, bluegill, pumpkinseed on Round 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.
Break off the point is the top-rated area: a drop-off in about 11 ft of water that rates prime for walleye in fall. Open the map above to see every rated spot for each 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.
