Hypertrophic Lakes
06/30/26
“What is the highest level of algal contamination for lakes?”
A lake’s trophic state index determines its algal power. Lakes at the highest end of the index (above 70) are classified as Hypertrophic Lakes. Hypertrophic lakes have very poor water quality and low water visibility. Algal overgrowth can be so intense that animals die off en masse from lack of dissolved oxygen.
