41-acre lake in Washburn County, Wisconsin. The lake tops out around 11 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Upper Kimball Lake maps at 41 acres behind 1.2 miles of shoreline. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Figure 0.5 mi of water from one end to the other, 0.3 mi at the beam. It sits in Washburn County. Middle Kimball Lake sits 0 mi south — the closest neighbouring chart.
Spring puts yellow perch in skinny water — 3 to 11 ft is the zone. Summer fish stay in 3 to 11 ft, and winter fish hold in 3 to 11 ft. Shallow bay flat is the standout, a weed flat at roughly 4 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 11 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 11 ft | dawn | Deep basin (11 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 11 ft | midday | Deep basin (11 ft) | Jigging spoon (small), Perch rig / spreader |

The summer box starts with a bucktail or a weedless spoon over cabbage.
