A preliminary study was conduct to know the water quality status of Bhagirathi River from March 2009- February 2010. A total of 4 sampling stations Goumukh, Gangotri, Uttarkashi and Rishikesh were selected. 15 physico-chemical parameters were study to know the water quality in different seasons (summer, monsoon and winter) in all the selected sampling sites. Water quality index of all 4 sites were show excellent status of water quality in summer and winter as comparison to monsoon its shows Good quality of water for Goumukh, Gangotri and Uttarkashi. In Rishikesh, WQI indicates the water quality in winter (Excellent) and good to poor quality in summer to monsoon season. The degradation of water quality in Rishikesh may be due to the anthropogenic activity like discharge of Sewage in Ganga, and tourism activity. The present study show the water quality of upper Ganga basin by using the water quality index.
