The paper deals with the assessment of water quality in the river Godavari, near Basara, Telangana. Water quality assessment in the river has been investigated for a period of two years (March 2017 - February 2019). Three sampling stations, covering a distance of 15 km were selected. Water and algal samples were collected near Basara, Nirmal district at an interval of one month for a period of 2 years. Also collected uniform size pebbles for benthic algae. Both phytoplankton and benthic algae have been studied. In the river Godavari three groups of benthic algae Bacillariophyceae, Cyanophyceae and Chlorophyceae were encountered. Bacillariophyceae were dominant at all the stations followed by Chlorophyceae and Cyanophyceae. All the physico-chemical parameters are well below the permissible limits.
