Dexter Lake vs Nepco Lake
Water quality, depth, fish species, and recreation comparison.
Nepco Lake has a higher water quality grade (A, Excellent) than Dexter Lake (F, Very Poor). Both are in Wood County, Wisconsin.
Both Dexter Lake 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 Dexter Lake (F). 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?
Dexter Lake
Very murky, less than 1.5 ft of visibility.
Nepco Lake
Good clarity, visible to about 11 ft.
Side-by-Side Metrics
| Metric | Dexter Lake | Nepco Lake |
|---|---|---|
| Overall Grade | F (Very Poor) | A (Excellent) |
| Water Clarity | 1.5 ft | 11 ft |
| Phosphorus | 483 µg/L | 10.9 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | - |
| Surface Area | 298 acres | 494 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | hypereutrophic | 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 Dexter Lake's Grade F. Water clarity: 11 ft vs 1.5 ft. For fishing diversity, Nepco Lake also leads with 0 species.
