These parameters change widely due to many factors like source of water, type of pollution, seasonal flucations etc. The urban pond is influenced by several extrinsic factors which may alter the structural and functional components of such ecosystem. The present study deals with the seasonal variation in the water quality of the urban pond – Sama of Vadodara City (Gujarat) during November 2007 to October 2009. The samples were collected from three different sites, having varied external influences. Various physico-chemical parameters like pH, temperature, acidity, alkalinity, hardness, chloride, dissolved oxygen, phosphate, nitrate etc. were analyzed. Significant seasonal variation was observed during the study for various parameters which was compared for different sites. The results were correlated to external influences and human interference.
