 ABSTRACT

In this study, the diatom diversity was investigated with physico- chemical parameters to reveal the water quality. The samples were collected every month from three different sites of the lake for a period of 12 months from January 2015 to December 2015. During investigation, a total of 63 diatom species were found. The dominant species in the study period were Nitzschia palea, N. frustulum, Cyclotella meneghiniana, Fragilaria ulna, Gomphonema gracile, Cymbella affinis, Eunotia arcus, Synedra acus, Synedra ulna, A. minutissima, Gomphonema sp. and Pinnularia gibba. Achnanthidium minutissimum and Cymbella affinis were present especially in unpolluted areas and Nitzschia palea and N. frustulum were observed in eutrophic sites. The distribution of diatom are not similar in all the sites, distribution of diatom species in the sampling site were explained by variations in physico- chemical parameters such as pH, EC, temperature, DO, TDS, TH, TA, BOD and COD.   This study concludes that diatom taxa in relation to physico- chemical variables will be helpful to design water quality monitoring programs.

Keywords: Physico- chemical, Diatom, Bioassessments, Water quality, Lake.
