Epipelic and epiphytic diatoms were collected monthly for two years from three sampling stations in Karagol Lake to investigate the relationship between seasonal variations of benthic diatoms and physicochemical variables. A total of 62 diatom taxa were determined. Cymatopleura solea, Cymbopleura amphicephala, C. minuta, Fragilaria construens, Gomphonema angustum, G. olivaceum, Hannaea arcus, Navicula cryptocephala, N. radiosa, N. rhyncocephala, Nitzschia microcephala, Pinnularia interrupta and Surirella tenera were the most conspicuous diatoms in terms of frequency of occurrence and relative abundance in the epipelic and epiphytic communities. Light and water temperature were found to be a more important factors in the growth of diatoms in this study.
