In the present study, seasonal variation in physico-chemical parameters of water of Sun Temple pond at Kochas, Rohtas (Bihar) is reported from January,2014 to December,2015. An average value of atmospheric temperature was recorded 26.51�10.2�C, water temperature 22.7�9.05�C, pH 7.05�0.31, conductivity 1008.46�125.95 ?mho/cm, dissolved oxygen 5.83�0.83 mg/l, biochemical oxygen demand 3.86�1.26 mg/l, total alkalinity 238.94� 26.50 mg/l, hardness 193.87�45.24 mg/l, total dissolved solid 589.22�77.49 mg/l, chloride 13.60�2.19 mg/l, nitrate 1.3175� 0.18 mg/l and phosphate 0.2925�0.06 mg/l in this study. Statistical analysis inferred that air temperature and water temperature is negatively correlated to pH, dissolved oxygen, and phosphate but positively to conductivity, biochemical oxygen demand, nitrate, total alkalinity, chloride, hardness and total dissolved solid. On the other hand, pH showed negative correlation to biochemical oxygen demand, total alkalinity, chloride, hardness and total dissolved solid but positive correlation to conductivity, dissolved oxygen, nitrate and phosphate. Dissolved oxygen is also negatively correlated to biochemical oxygen demand, nitrate, total alkalinity, chloride, hardness and total dissolved solid but positively to phosphate. The study will help in understanding the present status of the water body, biodiversity of this system and also assessment of precautionary measures.
