Venna lake is one of the well known water reservoir from Western Ghats. It has gained importance as point of tourism and also because of the water supply to the hill station Mahabaleshwar. To know the quality of water and algal growth of this lake, physicochemical and biological parameters like temperature, pH, total alkalinity, dissolved oxygen, free CO, total hardness, phosphate, silica and algal biodiversity was carried out monthly from October 2013 to September 2014. Data obtained in this study has shown the correlation between physico-chemical parameters and occurance of algae found therein. Members of Chlorophyceae like Pediastrum, Scenedesmus and Staurastrum showed constant occurance throughout the year while some of the bloom forming algae like Microcystis observed only during summer season, Euglenoids showed presence during winter season.
