Water is a valuable natural resource very important for sustaining all life on the planet earth and is in continuous circulatory movement as hydrological cycle. The surface water bodies which are the most important source of water for human activity are unfortunately under several environmental stresses and are being treat ended as a consequence of development activity. The present work highlights the water quality index of sanjay nagar pond in katni. Water quality index (W.Q.I.) of this pond was calculated by some physicochemical parameters such as Temperature, Chloride, Alkanity, hardness, pH, Total dissolved solid, Turbidity, Chloride, DO, BOD and COD. The analysis shows that the water of study pond polluted due to the sewage water which have been coming from the nearby residential and factory areas. Application of Water Quality Index (WQI) in this study has been found useful in assessing the overall quality of water and to get rid of judgment on quality of the water. This method appears to be more systematic and gives comparative evaluation of the water quality of sampling site.
