Mirror Lake vs North Lemmon Lake
Water quality, depth, fish species, and recreation comparison.
North Lemmon Lake has a higher water quality grade (B, Good) than Mirror Lake (F, Very Poor). Both are in Adams County, Wisconsin.
Both Mirror Lake and North Lemmon Lake sit in North Dakota. 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. North Lemmon Lake (B) is materially cleaner than Mirror 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 — North Lemmon 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?

Side-by-Side Metrics
| Metric | Mirror Lake | North Lemmon Lake |
|---|---|---|
| Overall Grade | F (Very Poor) | B (Good) |
| Water Clarity | 2.1 ft | 5.7 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | 31.6 µg/L | 4.8 µg/L |
| Maximum Depth | - | - |
