摘要：Surha Lake, located in district Ballia ofstate Uttar Pradesh in India,is the source of livelihood for the local human population and habitatofa large number of birds and other species. The present study aims to assess the ecological health of the lake during wet and dry season in year 2014-15 using EHI, NSFWQI, CTSI, and SDI. The result indicates that the lake is in eutrophic state as during wet and dry season average CTSI was 76.30 and 79.49respectively,and average NSFWQI was reported in medium water quality range, which is not suitable for human use. The SDI was found to be 0.67 and 0.65 in wet and dry season i.e. poor diversity. The ecological health of the lake was also found to be in the medium category indicated by EHI of 2.5 in both seasons. Therefore, suitable conservative measures need to be adopted to recover the good ecological health of the lake.
