Bad Medicine Lake reads lower on nutrients and algae than Height of Land Lake. Both are in Becker County, Minnesota.

Reviewed by LakeQuality Editorial Team · Updated

Both Bad Medicine Lake and Height of Land 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: Bad Medicine Lake carries clearly lower phosphorus and chlorophyll-a readings than Height of Land 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: 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?

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.

Verdict

Bad Medicine Lake reads lower on nutrients and algae than Height of Land Lake. Water clarity: 25 ft vs 6.6 ft. For fishing diversity, Bad Medicine Lake also leads with 13 species.
