48-acre lake in Menominee County, Wisconsin. The lake tops out around 37 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. The season-by-season read for each species follows, from the map's own numbers.
On the chart, Round Lake draws 48 acres inside 1 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. 32% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 0.4 mi of water from one end to the other, 0.3 mi at the beam. You'll find it in Menominee County. For a second option, Little Blacksmith Lake lies 1 mi northwest.
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring largemouth bass. Plan around early morning and the evening in the warm months. 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 (4 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shoreline break (17 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (4 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Shoreline break (17 ft) | Blade bait, Jigging spoon |
Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 31 ft.

Shallow bay flat is the top-rated area: a weed flat in about 4 ft of water that rates prime for largemouth bass in spring. Every other rated spot, per species and season, is on the map above.
