Abstract:
The vast resources of water in form of lakes, wetlands, streams and rivers, due to their peculiar natural conditions, are prime centres of cold water fisheries and thus have a major contribution in its development. Manasbal Lake is the deepest freshwater valley lake of Kashmir located in Ganderbal district at mean latitude of 34°15' N and longitude of 74°40'E. Manasbal Lake is warm monomictic urban lake in Kashmir and remains thermally stratified for 8–9 Months The present study on Manasbal Lake, was undertaken from December 2019 – November 2020 to determine various physico-chemical parameters like Temperature, Depth, Dissolved oxygen, pH, Chloride, Free Carbon Dioxide, Ammoniacal Nitrogen, Nitrate Nitrogen and Total Phosphorous along vertical gradient. The bottom levels of the lake was found to be oxygen deficit (O2 < 1 mg/L), which is indicative of the water body’s more eutrophic nature. Clinograde type of Dissolved Oxygen curve was recorded, also pH values showed a decreasing trend while Free Carbon dioxide, Chloride, Nitrate Nitrogen, Ammoniacal Nitrogen and Total Phosphate showed increasing trend from surface to bottom waters.
