The shoreline benthic diatoms of Asartepe Dam Lake were identified from different habitats (epipelic, epiphytic, and epilithic) at 7 sampling stations between April 2003 and June 2004. In the investigation, a total of 93 taxa were identified.

In the investigation, a total of 93 taxa were identified. Of those, Cymbella affinis Kütz., Navicula radiosa Kütz., Ulnaria ulna (Nitzsch) Compère, Pinnularia borealis Ehrenb., Amphora ovalis (Kütz.) Kütz., Cyclotella ocellata Pant. and Nitzschia dissipata (Kütz.) Grunow were observed and abundant at all stations. Some physical and chemical water quality parameters were measured and correlated with biological parameters.
