Unnamed Lake vs White Bear Lake
Water quality, depth, fish species, and recreation comparison.
White Bear Lake reads lower on nutrients and algae than Unnamed Lake. 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 reads materially cleaner than Unnamed Lake on nutrients and algae. 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 gap in the readings is decisive: White Bear Lake has the lower nutrient and algae numbers. 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 |
|---|---|---|
| Water Clarity | 3 ft | 14.4 ft Better |
| Phosphorus | 77 µg/L | 15 µg/L Better |
| Chlorophyll-a (Algae) | 28.5 µg/L | 2.7 µg/L Better |
| Maximum Depth | 60 ft | 83 ft Better |
| Surface Area | 1,799 acres | 2,428 acres |
| Public Access | Yes | Yes |
| Fish Species | 12 | 18 Better |
| Trophic State | eutrophic | mesotrophic |
A green ✓ marks the better value for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better). Surface area and trophic state carry no tick — a bigger lake is not a better lake.
