For the present study, Jawan canal also known as “Jawan Nehar” was selected. Jawan canal was constructed near the sumera hydroelectric power plant to use the Ganges canal as a source of water to generate electricity. Sampling was done between 7 am and 9 am on fortnight basis from 30th March, 2015 to 12 June, 2015. During the investigations total fourteen species of phytoplankton belonging to different families were recorded as Ankistrodesmus sp., Cosmarium sp., Clostridium sp., Closteriopsis sp., Diatoma sp., Genicularia sp., Fragilaria sp., Nostoc sp., Navicula sp., Nitzchia sp., Oscillatoria sp., Spirogyra sp., Scenedesmus sp., and Spirulina sp. Phytoplankton in Jawan Nehar varied from a minimum of 86 No/ml on 30th April, 2015 to a maximum of 159 No/ml on 30th March, 2015. Statistically, phytoplankton showed positive correlation with zooplankton (r = 0.608) and with dissolved oxygen (r =0.501); significant negative correlation with water temperature (r = - 0.682), carbon dioxide (r = - 0.690) and pH(r = - 0.504) and total seven species of Zooplankton belonging to different families were recorded as Brachionus sp., Cyclops sp., Cypriodopsis sp., Diaptomus sp., Keratella sp., Mesocyclops sp. and Philodina sp. zooplankton in Jawan Nehar varied from a minimum of 27 No./ml on 30 April, 2015 to a maximum of 54 No./ml on 15 April, 2015 . Statistically, zooplankton showed significant negative correlation with carbon dioxide (r = -0.568).
