In this study Cyanobacteria species of Mogan Lake, Beytepe Pond and Delice River were taxonomically investigated. The flora of algae (cyanobacteria) specimens have been collected by monthly intervals from Mogan Lake and Beytepe Pond during the periods of October 2011 and September 2012. For the Delice River the laboratory samples which were collected by montly intervals between July 2007-May 2008 have been evaluated. Phytoplankton samples, have been collected horizontally and vertically using by a plankton net and Patala sampler and fixed in 4% formaldehyde solution. A small portion of each sample was prepared for identification, counting and then photographed under the microscope. During the study physio-chemical parameters such as the temperature, soluble oxygen, salinity and pH values were measured in situ. In the study, Cyanobacteria species diversity, seasonal distribution have been observed and their seasonal succession have been evaluated according to physico-chemical variables. As a result, totally 15 genus and 41 taxon were identified from three different habitats. Among them 22 species were identified in Mogan Lake, 19 species in Beytepe Pond and 13 species in Delice River respectively. During the study species like Lyngbya limnetica and Aphanocapsa incerta were frequently observed for all months in Mogan Lake, Chrococcus turgidus and Chrococcus minimus were high number in Beytepe Pond while Phormidium formosum was dominant in Delice River. As a result species number and density were generally rich in Mogan Lake during fall and summer season while very low in the Delice River during winter season.
