Abstract
The present study deals with the assessment of water quality of four lakes namely TV-station reservoir, Yelebethur lake, Bathi lake and Hadadi lake in and around Davangere city. The physicochemical characteristics were studied and analyzed during September 2003 to August 2005. The present study shows detailed account on physico-chemical characteristics and quality of water. The summer, rainy and winter seasons show fluctuations in various physico-chemical parameters. The present investigations indicates that BOD values were relatively high in case of Bathi lake when compared to TV-Station Reservoir and Yelebettur Lake.Bathi Lake and Hadadi lake recorded relatively high turbidity. BOD values recorded maximum in Hadadi lake with 7.0 mg/L and in Bathi lake with 5.9 mg/L. COD recorded maximum in Bathi lake with 225 mg/L and in Hadadi lake with 110 mg/L during summer. High COD value indicates organic pollution in Hadadi and Bathi lakes.
