29-acre lake in Waukesha County, Wisconsin. The lake tops out around 15 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 30 acres of water rimmed by 1.9 miles of bank, with a single island in the mix. With a shoreline index of 2.4, this water is all arms and coves — edge habitat well beyond its acreage. The basin spans about 0.4 mi end to end and 0.3 mi across at its widest. You'll find it in Waukesha County. For a second option, Okauchee Lake lies 1 mi southeast.
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 5 to 15 ft; cold water stacks them in 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 3 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 (3 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 15 ft | dawn & dusk | Break off the point (7 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 | 5 to 15 ft | midday | Break off the point (7 ft) | Blade bait, Jigging spoon |
Structure-wise the chart holds 5 features, led in depth by Deep basin at roughly 13 ft.
