Whether a eutrophic lake is dominated by either macrophytes or blue-green algae depends on the pre~impact condition of the lake and nutrient loading rates. Eutrophic Lake.

The genus Gallionella constitutes a major microbial population in the metalimnion of an eutrophic lake. In the case of oligotrophy the vertical oxygen distribution is essentially uniform, or orthograde. The exchange of sediments and water disrupts the restoration of the ecosystem.
