Samples were preserved with standard procedures. Identifications were made by Leica Digital Imaging System and processed with Adobe Photoshop. A total of 42 taxa (including species, varieties, forms and subspecies) belonging to 24 genera have been recorded. Both centrales and pennales were present, notably 16% of total flora were marine and 84% freshwater forms. Thalassiothrix spp., Coscinodiscus curvatulus, Actinocyclus actinocyclus, Eucampia balaustium, Hemidiscus cuneiformis, Muelleria peraustralis, Chamaepinnularia cymatopleura were marine and brackish water species. Among the fresh water flora Nitzschia (18.42%), Navicula (13.15%), Pinnularia (10.52%) and Luticola (7.89%) were species rich genera. Samples were preserved in formalin solution and refrigerated at 4 ?C. Each sample was treated with Hydrochloric acid and H202. The treated material was dried onto cover slips and mounted onto permanent glass microscope slides with the mounting medium Naphrax. Relative abundance of diatom species was determined using a light microscope with a lOOx oil objective.
