Abstract: Lakes are sometimes subjected to wastewater discharges originating from different sources. Chemicals such as nitrogen, phosphorus and carbon in certain concentrations might distort and disrupt aquatic ecosystems. The purpose of this study is to assess water quality of Sawanga (Vithoba) lake. Sawanga Lake is located in district Amravati Maharashtra. This study began in Feb 2011 and was carried out for 12 months by taking monthly water samples from five different stations of the lake. Water quality parameters like pH, Temperature, Total dissolved solids, Total Alkalinity, Total hardness, Phosphorus, Nitrate, Turbidity, Fluoride, chloride, Dissolved Oxygen, Ammonia, Iron, Turbidity and Conductivity analysis were done. This study indicates that Sawanga Lake has not reached the polluted stage yet.
