Abstract: Seasonal variation of physicochemical parameters of water was studied in Deepar beel at Dharapur area near to Khonajan, the channel connecting the beel with the river Brahmaputra. The adjoining area of the beel at the studied area and the channel were observed to fill with domestic households. Sometimes dumping of garbage was also observed near the study area from where effluents are observed to be released to the beel water through surface runoff water during heavy rains thus creating imbalance in the chemistry of water. The elevations of total alkalinity upto 116 mg.l-1 and total hardness upto 318 mg.l-1 along with nutrients like calcium, magnesium, potassium, sulphate, phosphate and subsequent decrease of dissolved oxygen particularly in summer season (March-May) are very interesting and appeared to be governed by rainfall. The high rainfall observed in summer season after comparatively dry season in winter has changed the property of water through allochthonous nutrient flux from the peripheral area where garbage was observed to dump. The low level of oxygen in summer months was not only due to higher temperature but also due to high organic load of water.
