Clearwater Lake vs Emily Lake
Water quality, depth, fish species, and recreation comparison.
Clearwater Lake reads lower on nutrients and algae than Emily Lake. Both are in Crow Wing County, Minnesota.
Both Clearwater Lake and Emily Lake sit in Minnesota. A same-state comparison strips out the state-level water-quality regime as a variable: any differences in the readings here are about the lakes themselves, not the agencies sampling them. The readings are meaningfully apart: Clearwater Lake carries clearly lower phosphorus and chlorophyll-a readings than Emily Lake. A spread that wide reflects real underlying differences, in watershed inputs, depth profiles, or monitoring rigor.
For a recreational visitor, the wider gap in the readings is decisive: Clearwater 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?
Clearwater Lake
Good clarity, visible to about 13 ft.
Emily Lake
Very murky, less than 3 ft of visibility.
Side-by-Side Metrics
| Metric | Clearwater Lake | Emily Lake |
|---|---|---|
| Water Clarity | 13 ft Better | 3 ft |
| Phosphorus | 12 µg/L Better | 53 µg/L |
| Chlorophyll-a (Algae) | 3.7 µg/L Better | 30 µg/L |
| Maximum Depth | 54 ft Better | 13 ft |
| Surface Area | 905 acres | 721 acres |
| Public Access | Yes | Yes |
| Fish Species | 16 Better | 13 |
| Trophic State | mesotrophic | eutrophic |
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.
