During the present study, water quality index (WQI) was calculated to assess the water quality of Barna stream network of Narmada River basin in Madhya Pradesh. A total of eight physicochemical parameters viz., pH, conductivity, dissolved oxygen, total hardness, nitrate etc. were considered to estimate the water quality index. The methodology for physicochemical analysis was followed from APHA (1998) and Adoni (1985). The results obtained during the survey showed that the WQI score at six stations in Barna stream network were within the range of scale 26-50 exhibited ‘Good’ water quality at each station, reflecting the healthy ecological conditions within the watershed of the Barna stream network.
