An attempt has been carried out to assess the seasonal water quality index (WQI) using four water quality parameters pH, BOD, DO, FC. For which 10 different stations along Pravara River have been selected which covers two seasons pre-monsoon and post-monsoon. Physico-chemical parameters have been analyzed by standard method. The Karl Pearson correlation matrix has been established to examine relationship between the water quality parameters. The study is conducted to analyze the water quality status of Pravara River in terms of water quality Index (WQI). The computed WQI values are found between 37.5 to 78.9. The WQI values shows non-polluted water at upper stream in the study area, but as it enters in city considerable changes in WQI were observed and water become polluted (S₆ & S₁₀) to heavily polluted (S₅ & S₇). These Field observations reveal that water quality is declined due to many human activities mainly industrial, domestic and religious. To analyze that Physio-chemical characteristics of water and WQI is the main aim of the research with remedial measures to mitigate the deterioration and related consequences in future.
