16-acre lake in Sauk County, Wisconsin. The lake tops out around 12 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. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 16 acres, worked by 1.6 miles of shoreline. An index of 2.9 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. End to end it runs roughly 0.8 mi. It sits in Sauk County. Its nearest charted neighbour, Lower Wisconsin River, is 2 mi to the west.
The spring pattern is a shallow one: walleye in 3 to 12 ft. The depth story barely changes: 4 to 12 ft through summer, 4 to 12 ft in winter. The spot to know is Break off the point, a drop-off in about 5 ft of water that rates prime for walleye in fall. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.

|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |

In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer keeps them at 4 to 12 ft, and they winter in 4 to 12 ft.

You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
