Abstract
Physico-chemical characteristics and phytoplankton diversity of Nagathibelagalu tank of Bhadravathi town was studied for a period of twelve months from January to December 2008. The estimated water quality parameters were compared with the standard values prescribed by the Bureau of India Standards (BIS) and World Health Organization (WHO). The results of physico-chemical analysis revealed that water is polluted due to high BOD, free CO2, phosphate and nitrate. A total of 44 species belonging to 29 genera of phytoplankton were recorded, of which Chlorophyceae and diatoms were found to be dominant among four classes. Pollution tolerant species such as Scenedesmus sp., Coelastrum sp., Euglena sp., Trachelomonas sp. and Microcystis aeruginosa were observed.
