Black Oak Lake
Black Oak Lake is widely regarded as one of the clearest lakes in Wisconsin, with Secchi disk readings exceeding 50 feet. Spanning 564 acres with an average depth of 34 feet, the water clarity is immediately noticeable and defines the entire experience on the lake.
Located west of Land O’ Lakes, the setting feels distinctly north and lightly traveled while still being close to groceries and everyday services. The shoreline is heavily wooded and lightly developed, with nearly five acres of water per owner and fewer than 16 owners per mile of shoreline, preserving long sightlines and a clean, natural appearance from the water.
The active and conservation-minded Black Oak Lake Association plays an important role in protecting water quality. A well-maintained public launch and beach add accessibility, and fiber internet availability supports modern lake living.
Buyers drawn to Black Oak typically prioritize exceptional clarity, depth, privacy, and a community committed to stewardship. For more information, see my Black Oak Lake blog post.

This is a summary based on available information.
DNR and fishing resources list a mixed fish community that can include panfish, smallmouth and largemouth bass, northern pike, trout, and walleye, with overall health bolstered by the lake’s clean, well‑oxygenated water. The same clarity that draws swimmers and paddlers can make fish wary in bright conditions, so experienced anglers often favor early and late windows, wind‑blown shorelines, and deeper structure rather than shallow flats at midday. Because the lake is less trafficked than some bigger destinations, fish can be less conditioned to heavy pressure but still require thoughtful presentations in the ultra‑clear water.
