Hypereutrophic

Hypereutrophic lakes are very nutrient-rich lakes characterized by frequent and severe nuisance algal blooms and low transparency. Hypereutrophic lakes are the most biologically productive lakes, and support large amounts of plants, fish and other animals. Hypereutropic lakes have a visibility depth of less than 3 feet, they have greater than 40 micrograms/liter total chlorophyll and greater than 100 micrograms/liter phosphorus.
