Abstract: In the present study, the work reveals about how the domestic wastewater is contaminating the Bathi lake, located in Davangere city also to know how it is effecting the physical and chemical parameters of the lake. They include pH, Electrical Conductivity, turbidity, Total Hardness, Calcium, Magnesium, chloride, Total Dissolved Solids, Dissolved Oxygen, Biological Oxygen Demand, Chemical Oxygen Demand, Sodium and potassium. The work was carried out during January 2016 to April 2016 for four months. Four stations have chosen in the lake. Station 1 – Domestic wastewater entering the lake. Station 2 – Domestic wastewater joining the lake. Station 3 – Domestic wastewater diluted with the lake which is far away from station 2. Station 4 – The lake water is taken. The results were compared WHO standards and BIS and some of the parameters were crossing the desired limits. Hence the work concludes that the quality of lake is poor and is unsuitable for human consumption
