94-acre reservoir in Juneau County, Wisconsin. The lake tops out around 10 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. The season-by-season read for each species follows, from the map's own numbers.
The outline encloses 94 acres, worked by 2.2 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. End to end it runs roughly 0.9 mi, about 0.3 mi across. It sits in Juneau County. Big Lake* sits 3 mi northwest — the closest neighbouring chart.
Spring puts yellow perch in skinny water — 3 to 10 ft is the zone. Summer fish stay in 3 to 10 ft, and winter fish hold in 3 to 10 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
