This research is deals with water quality of Kosi River during 2021. Water samples were collected on a monthly basis from four sites namely Gargiya, Ringhor, Kosi Barrage, and Sultanpur Patti. Physico-chemical parameters such as temperature, total solids (TS), total dissolved solids (TDS), total suspended solids (TSS), transparency, Velocity, dissolved oxygen (DO), pH, chlorides, and alkalinity were analyzed during the study. In present investigation sultanpur patti was found to be the most polluted as compared to others. It was also observed that manmade activities responsible for water quality degradation in Kosi River in general and at site-IV i.e. Sultanpur Patti in particular.
