72-acre lake in Waushara County, Wisconsin. The lake tops out around 19 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Round Lake runs 72 acres with 1.4 miles of edge. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. The shallow band under 15 ft claims about 75% of the surface — that's where the groceries are. Tip to tip the water measures near 0.4 mi with a 0.4-mi widest point. You'll find it in Waushara County. The nearest mapped water is Kusel Lake, 1 mi to the north.
Early season walleye use the shallows, holding in 4 to 15 ft. Expect a summer slide to 6 to 19 ft, then a winter hold in 6 to 19 ft. Put Break off the point first on the milk run — a drop-off near 13 ft that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Break off the point (13 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 6 to 19 ft | dusk & dawn | Break off the point (13 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 6 to 19 ft | dusk & night | Break off the point (13 ft) | Jigging rap, Jig + big minnow |
| Winter | 6 to 19 ft | dusk & dawn | Deep basin (19 ft) | Jigging spoon + minnow head, Rattle bait |
Spring yellow perch on Round Lake hold shallow, usually 3 to 12 ft. They move out to 6 to 19 ft in summer and finish the year down in 6 to 19 ft. Put Back-bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 19 ft | dawn | Deep basin (19 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 19 ft | midday | Deep basin (19 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 19 ft | midday & dawn | Deep basin (19 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 6 to 19 ft; cold water stacks them in 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 6 to 19 ft | dawn & dusk | Break off the point (13 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (13 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Back-bay flat (4 ft) | Tip-ups, Large jigging spoon |
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 6 to 19 ft before dropping to 6 to 19 ft for winter. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 2 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 6 to 19 ft | dawn & dusk | Break off the point (13 ft) | Texas-rigged 10" worm, Deep-diving crankbait |

Spring puts crappie in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 6 to 19 ft; cold water stacks them in 6 to 19 ft. Deep basin is the standout, a deep basin at roughly 19 ft, rated prime for winter crappie. Plan around early morning and the evening in the warm months. A jig trolled/spider-rigged or a small crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | 1/16 oz jig + tube, Curly-tail grub |

Anglers target walleye, yellow perch, northern pike, largemouth bass, crappie, bluegill 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 13 ft of water that rates prime for walleye in fall. Scroll up to the map for the complete spot list by 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.
