摘要:Limnological parameter and plankton diversity are an important criterion for determining the suitability of water for irrigation and drinking purpose. River Bhagirathi has greatest importance for humankind. The specific status of Physio-chemical parameter and diversity of plankton in River Bhagirathi have been studied through monthly surveys in two annual cycles (2010-11 and 2011-12) and annual survey of fishes in two annual cycles (2010-11 and 2011-12). The water remained moderately alkaline (pH 7.7) while velocity (1.23m/s), TS (844mg/l), chloride (5.04mg/l), hardness (96.73mg/l) and alkalinity (67.11mg/l) showed low mean values. Average dissolved oxygen levels were at 8.54mg/l while average nitrate and phosphate levels were 0.048mg/l and 0.072 mg/l respectively.
