Bad Medicine Lake vs Wolf Lake
Water quality, depth, fish species, and recreation comparison.
Bad Medicine Lake reads lower on nutrients and algae than Wolf Lake. Both are in Becker County, Minnesota.
Both Bad Medicine Lake and Wolf 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. Bad Medicine Lake reads materially cleaner than Wolf 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: Bad Medicine 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?

Side-by-Side Metrics
| Metric | Bad Medicine Lake | Wolf Lake |
|---|---|---|
| Water Clarity | 25 ft Better | 3.9 ft |
| Phosphorus | 6 µg/L Better | 25 µg/L |
| Chlorophyll-a (Algae) | 1.6 µg/L Better | 6.9 µg/L |
| Maximum Depth | 84 ft Better | 16 ft |
| Surface Area | 803 acres | 1,460 acres |
| Public Access | Yes | Yes |
| Fish Species | 13 Better | 11 |
| Trophic State | oligotrophic | 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.
