The seasonal variations in the physico-chemical parameters of Barjaani Talaab and Baba Santokh Singh Ji Temple pond of Jammu were studied from February, 2016 to January 2017. The parameters that were determined included temperature, pH, transparency, depth, dissolved oxygen (DO), free carbon dioxide, alkalinity, hardness (calcium, magnesium), chloride, biological oxygen demand (BOD), phosphate, sulphate and nitrate concentrations. Monthly variability of various physicochemical parameters was analyzed and statistically, relationships between various physicochemical parameters were also calculated which indicated the strong correlation between various parameters like water temperature, DO, SO4 2- , FCO2, Ca2+, Mg2+ etc. The results indicated that the water quality was polluted in both the ponds and the consistent rise in the values of these parameters due to increased input of domestic waste and agricultural runoff from the catchments may further degrade the quality of the water bodies. Also a comparative account of these two ponds indicated that as such the values in case of Barjaani Talaab were higher, so this pond was found to be more polluted than the Baba Santokh Singh Ji Temple Pond. In this attempt the analysis of these abiotic components also revealed the fact that abiotic components are governed by various anthropogenic activities and they in turn affect the biotic components of the water body and so set guidelines for the population dynamics and seasonality of various groups of zooplankton inhabiting any water body.
