Unnamed Lake vs White Bear Lake
Water quality, depth, fish species, and recreation comparison.
White Bear Lake has a higher water quality grade (A, Excellent) than Unnamed Lake (D, Poor). Both are in Washington County, Minnesota.
Unnamed Lake and White Bear Lake are both in Minnesota — a same-state head-to-head where the comparison comes down to lake-specific differences in depth, watershed, and monitoring history rather than the broader state-level water-quality regime. White Bear Lake (A) is materially cleaner than Unnamed Lake (D). 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 — White Bear 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?
Unnamed Lake
Very murky, less than 3 ft of visibility.
White Bear Lake
Good clarity, visible to about 14.4 ft.
Side-by-Side Metrics
| Metric | Unnamed Lake | White Bear Lake |
|---|---|---|
| Overall Grade | D (Poor) | A (Excellent) |
| Water Clarity | 3 ft | 14.4 ft |
| Phosphorus | 77 µg/L | 15 µg/L |
| Chlorophyll-a (Algae) | 28.5 µg/L | 2.7 µg/L |
| Maximum Depth | 60 ft | 83 ft |
| Surface Area | 1,799 acres | 2,428 acres |
| Public Access | Yes | Yes |
| Fish Species | 12 | 18 |
| Trophic State | eutrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
White Bear Lake wins on overall water quality with a Grade A versus Unnamed Lake's Grade D. Water clarity: 14.4 ft vs 3 ft. For fishing diversity, White Bear Lake also leads with 18 species.
