Abstract : Water quality assessment conducted in the tributaries of Ganga River in the year 2012 and 2013 identified hu- man activities as the main sources of pollution. For the study three tributaries of river Ganga in Uttarakhand were chosen i.e. Alaknanda (A), Bhagirathi (B) and Ganga (G). Water samples were collected from five sampling stations on river Alaknanda viz. Devprayag (A1), Rudraprayag (A2), Karnaprayag (A3), Chamoli (A4) and Vishnuprayag (A5), only one sampling station on Bhagirathi near residential area at Devprayag (B), two sampling station on river Ganga viz. Har ki pauri (G1) and Rishikesh (G2). The samples were analysed for physical and chemical parameters using standard methods. The sample temperatures ranged from 7.7 –18.3 0C. Summer maxima and winter minima were observed at all the sites of sampling stations (A, B and G). pH ranged from 7.4 - 8.2, DO ranged from 7 – 8.61 mg/l and BOD ranged from 0.2 – 1.9 mg/l. All samples showed permissible limit except samples from Harki pauri and Rishikesh on river Ganga.
