Abstract:
Water quality plays an important role in determining the status and condition of that fresh water ecosystem. Present investigation was undertaken to evaluate the water quality status of Manasbal Lake located at a distance of 30 km north from Srinagar. The lake was investigated for a period of 11 months from December 2019 to November 2020 and a total of 10 Physico-chemical parameters were analyzed at six different sites at monthly intervals by following standard methods. Among the various parameters recorded the Air temperature ranged from 2.7°-31 °C and Water temperature 3-29.7 °C,Depth 0.9-11.5m, Dissolved oxygen 6-11.2mg/l, pH7-9.2; Chloride 16-34.9mg/l, Free carbon dioxide0-18mg/l, Ammonical nitrogen 33.1-108 μg/l, Nitrate Nitrogen 190 - 353.2 μg/l and Total Phosphorous ranged from 131-288.1μg/l. The investigation revealed that almost all the above parameters show that the pollution load is increasing due to anthropogenic pressure untreated sewage and solid garbage from residential areas, fertilizers containing Nitrates and Phosphates which had resulted in the eutrophic condition of the lake. So immediate remedial measures should be taken for its protection from further depletion.
