P. and Sr. Nirmala, T.Abstract The present investigation was aimed to evaluate the surface water by analysing the physico-chemical parameters in Vaigai reservoir and Pickup dam from February, 2016 to March, 2018. Physical and chemical properties were analyzed using APHA methods and the result of 16 parameters was used for Water Quality Index analysis. It was high in Vaigai reservoir than in Pickup dam. Water of Vaigai reservoir was good except Southwest monsoon I and II, Northeast monsoon I and winter II.
