Lake Sherwood vs Nepco Lake
Water quality, depth, fish species, and recreation comparison.
Nepco Lake has a higher water quality grade (A, Excellent) than Lake Sherwood (C, Fair). Both are in Wisconsin.
Both Lake Sherwood and Nepco 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. Nepco Lake (A) is materially cleaner than Lake Sherwood (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 — Nepco 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?
Lake Sherwood
Murky, only visible to about 5.5 ft.
Nepco Lake
Good clarity, visible to about 11 ft.
Side-by-Side Metrics
| Metric | Lake Sherwood | Nepco Lake |
|---|---|---|
| Overall Grade | C (Fair) | A (Excellent) |
| Water Clarity | 5.5 ft | 11 ft |
| Phosphorus | 22.6 µg/L | 10.9 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | - |
| Surface Area | 246 acres | 494 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | eutrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Nepco Lake wins on overall water quality with a Grade A versus Lake Sherwood's Grade C. Water clarity: 11 ft vs 5.5 ft. For fishing diversity, Nepco Lake also leads with 0 species.
