A study was carried out on Pakhal Lake to assess the impact of anthropogenic events sewage, agricultural runoff pollution on the water quality of the lake. Physico chemical parameters such as temperature, electrical conductivity, Dissolved Oxygen, Bio-Chemical Oxygen Demand, Chemical Oxygen Demand, Total Hardness, Total Alkalinity, chlorides, calcium, magnesium and organic matter and eutrophic factors like phosphates and nitrates were observed as per WHO guidelines. The Coliform bacteria were found to be high in the banks of the tank. All these parameters are in permissible limits. Hence, it can be recommended for aquaculture drinking and irrigation purpose.
