The algae were used to assess the water quality of Nagapur and Chandapur dams. The pollution indicator genera and species of algae from each of three (3) stations of both dams were recorded, this was done with the help of palmer’s index of pollution indicator species of algae. For knowing the quality of water samples the total score of station were recorded greater than 15 indicator species were found which helped to know the high degree of organic pollution of dam. The genera observed at different stations of both dams, were 18 and 21 out of the 34 pollution indexed speices of palmer. The 18 genera were recorded at Nagapur dam and 21 genera at Chandapur dam.
