Different water quality parameters like SST, pH, transparency, dissolved oxygen, salinity, sulphate and nutrients like silicate, phosphate (orthophosphate and total phosphate), nitrite, and nitrate were analyzed during the study period. In addition to this special focus was given to plankton diversity and its relation with different hydrological parameters. Variation in water quality as well as in plankton diversity was observed during the study period. The SST value was maximum during the month of September i.e.30.39°C and minimum during March i.e. 26.88°C. Whereas, pH was maximum during July and minimum during March i.e. 8.19 and 7.52 respectively. The study reported highest transparency of water in November month i.e.
