Abstract: The biodiversity study was executed to reveal the microalgal population in the Gundur Lake located in the southern part of Tiruchirappalli in Tamil Nadu, India. The samples were collected from the six chosen sites in the lake as algal mats and plankton samples during March 2014. In total, 81 species were reported which includes 35 species belongs to Chlorophyta, 9 species belongs to Bacillariophyta and 37 species belongs to Cyanophyta. Eight microalgal genera such as Pediastrum, Cosmarium rhophalodia, Microcystis, Chroococcus, Oscillatoria, Scytonema and Gloeotrichia were found predominant in the lake. Physicochemical parameters of the water samples were also analysed to evaluate the algal diversity. The suitable trophic condition and eutrophic nature of the lake favoured the algal dominance and bloom formation.
