The present analysis deals with the study of physico-Chemical nature of water from Durgham Cheruvu. Water from 3 sites were collected monthly for one year from August, 2012 to July, 2013 analyzed for parameters like chlorides, pH, Atmospheric Temperature, Water temperature and Humidity. Throughout the study period Chlorides in water were 21 folds higher than normal value 8.3mg/l according to Livingstone 1963. The Atmospheric and Water temperatures are directly proportional to chloride concentration and the Humidity is inversely proportional to Chloride concentration in lake water. Therefore, the high levels of Cl was influenced by domestic sewage into the lake water in monsoon and evaporation in summer. Thereby there is an urgent need to evolve plan to protect the lake.
