Mesotrophic Lakes in Kansas
8 mesotrophic lakes in Kansas. Moderate nutrients, good water quality.
Most well-managed working lakes register as mesotrophic — the band that balances productivity with clarity. 8 lakes in Kansas sit in the mesotrophic band. About 0% are deep (50+ ft); the rest are shallower basins where watershed management keeps nutrients from pushing the system into eutrophy.
Mesotrophic lakes tend to grade B or C on our A–F scale — the productive-but-clear band lines up with the middle of the letter grades.
