Variations in the phytoplankton communities like Cyanophyceae, Chlorophyceae, Euglenophyceae, Bacillariophyceae, and Dinophyceae in two lakes of Udupi district, Karnataka have been discussed. This lake during a certain period supported as many as 26 species of Cyanophyceae, 30 species of Chlorophyceae, 7 species of Euglenophyceae, 8 species of Bacillariophyceae and 2 species of Dinophyceae. The growth of phytoplankton influenced by physicochemical parameters such as water temperature, dissolved oxygen, water pH, biological oxygen demand, chemical oxygen demand, nitrates, phosphates etc.
