Bad Medicine Lake vs Many Point Lake
Water quality, depth, fish species, and recreation comparison.
Bad Medicine Lake and Many Point Lake read the same on nutrients and algae. Both are in Becker County, Minnesota.
Both Bad Medicine Lake and Many Point 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. These two sit close on the readings, Bad Medicine Lake versus Many Point Lake. The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
With readings this close, the choice between the two lakes turns on non-water-quality factors: depth, fish species, public access, distance from home. The per-lake pages below cover all of those.
Bad Medicine Lake
Crystal clear, you can see 25 ft down.
Many Point Lake

Side-by-Side Metrics
| Metric | Bad Medicine Lake | Many Point Lake |
|---|---|---|
| Water Clarity | 25 ft Better | 10.7 ft |
| Phosphorus | 6 µg/L Better | 15.5 µg/L |
| Chlorophyll-a (Algae) | 1.6 µg/L Better | 6.3 µg/L |
| Maximum Depth | 84 ft | 92 ft Better |
| Surface Area | 803 acres | 1,701 acres |
| Public Access | Yes | Yes |
| Fish Species | 13 | 16 Better |
| Trophic State | oligotrophic | 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.
