The zooplankton density and diversity along with important physico-chemical parameters were studied on forth nightly basis from August, 2016 to March, 2017 in Nanak Sagar reservoir, Uttarakhand. Three sampling sites i.e. (A1, A2 & A3) were selected for regular sampling of zooplankton and water. The range of physico-chemical parameters i.e. water temperature, dissolved oxygen, free CO2, transparency, pH, conductivity, total dissolved solid, total alkalinity, nitrate and phosphate during the study period were 16.9 to 34 0C, 3.2 to 9.6 mgL-1, 0 to 6 mgL-1, 67.9 to 194 cm, 7 to 8.7, 118 to 336 μS cm-1, 91.7 to 156 mg L-1, 60 to 140 mgL-1, 0.22 to 0.64 mgL-1 and 0.043 to 0.2 mgL-1 respectively. The zooplankton mainly consisted of Rotifera, Copepoda, Cladocera, Ostracoda and Diptera. Out of 24 genera of zooplankton, 10 were from rotifera, 6 from cladocera, 5 from copepoda, 2 from ostracoda and 1 belonged to diptera group. The average density of zooplankton was 6250 individuals L-1, 4125 individuals L-1 and 4000 individuals L-1 at site A1, A2 and A3 respectively. The diversity of zooplankton showed their own maximum and minimum abundance during a particular season. The water quality parameters of Nanak Sagar reservoir reveal that the environmental conditions are good from the fisheries point of view.
