Clear Lake vs North Nokomis Lake

Water quality, depth, fish species, and recreation comparison.

Clear Lake has a higher water quality grade (A, Excellent) than North Nokomis Lake (C, Fair). Both are in Oneida County, Wisconsin.

Both Clear Lake and North Nokomis Lake sit in Wisconsin. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. Clear Lake (A) is materially cleaner than North Nokomis Lake (C). A gap that wide is unlikely to close in a single year of remediation work; it reflects multi-decade differences in the lakes themselves.

For a recreational visitor, the wider grade gap is decisive — Clear Lake is the better water-quality choice. For a researcher, the gap is the interesting part: what is different about the two watersheds, and which of those differences is mutable?
