Each river has its own level of water quality parameters. Krishna and Godavari rivers are major and large rivers in Peninsula India. Water availability is more in Godavari River. Krishna delta has the water scarcity problem due to unavailability of water in Krishna River. So Andhra Pradesh government took the decision to interlinking the rivers through Polavaram canal. In this study water samples collected from five different areas of Krishna river including the place where Godavari river water enter into the Krishna River. The water samples were analysed and PH, ammonia, nitrate, nitrite, total hardness, calcium hardness, sulphates and alkalinity were estimated. The major change observed that the mixed water PH is low (6.5) at the Godavari water enters into the Krishna River but it reach the neutral level (7.0) after mixing with Krishna river water and can be suitable for various uses. There are no drastic changes in quality of mixed water of Krishna River. Ammonia levels are not traced in all water samples. There is no significant change in values of alkalinity, total hardness, calcium hardness and sulphates, was observed in Krishna river after interlinking of Godavari river.
