The Water Quality Index (WQI) of the Thol Wetland was calculated based on water quality parameters like pH, Conductivity, Total Dissolved Solids, Phosphate, Alkalinity - as CaCO3, Total Hardness as CaCO3, Sodium, Potassium, Calcium, Magnesium, % Sodium, Sodium Absorption Ratio, Chloride and Sulphate. Physico chemical parameters of water samples were analyzed for summer, monsoon and winter seasons during the year 2015- 2016. The study included sampling and its analysis of water samples, parameter rating and water quality determination. WQI is calculated in context with the basic usage of Thol Wetland water viz. irrigation and propagation of wildlife.
