Mesotrophic Lakes in Georgia

Most well-managed working lakes register as mesotrophic — the band that balances productivity with clarity. 14 lakes in Georgia 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 sit in the middle of the phosphorus and chlorophyll-a range: productive but still clear, with readings that rarely reach the EPA's poorest condition class.
