Mesotrophic Lakes in Michigan

126 mesotrophic lakes in Michigan. Moderate nutrients, good water quality.

Most well-managed working lakes register as mesotrophic — the band that balances productivity with clarity. 126 lakes in Michigan 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 the LakeGrade rubric — the productive-but-clear band lines up with the middle of the letter grades.
