IDENTIFICATION OF ANTHROPOGENIC INFLUENCES ON WATER QUALITY OF KENGERI LAKE, BANGALORE, INDIAN. LATHA AND M. RAMACHANDRA MOHANAbstract Kengeri lake lies on Magadi hill range of Bangalore in India, it has undergone a progressive increase in eutrophication as a direct effect of receiving continuous agricultural and domestic effluents from land drainage and anthropological shifting. The most important parameters affecting the water quality are; TDS, pH, DO, BOD, nitrates and organic phosphates. Values of all these parameters are much more above the WHO standards, due to this the environmental conditions are unsuitable for the flora and fauna. The highest temperature during summer season, pH lies in the alkaline side in summer months. Further other parameters like electrical conductivity, sulphates, total hardness and turbidity values showed an increasing trend. All the above mentioned information revealed that the environmental parameter of Kengeri lake undergo continuous change due to climate change and entry of drainage. Therefore the main objectives of the present work are to study the present status of the lake and the effect of drainage on the water quality and its impact on flora and fauna.
