The results of phytoplankton investigation in the Sasyk Reservoir in the summer of 2013–2014 are presented. For this period, 160 species (163 infraspecific taxa including nomenclature type of species) from 8 divisions, 13 classes, 27 orders, 44 families, and 92 genera were revealed. The core of the phytoplankton taxonomical structure comprised representatives of Chlorophyta (66 species, 69 infraspecific taxa – 41%), Bacillariophyta (51 species – 32%), Cyanophyta (26 species – 16%), and Euglenophyta (6 species – 4%). Divisions Charophyta and Dinophyta containing 4 species, or 2.5% each, Xanthophyta – 2 species, or 1%, Chrysophyta – 1 species, or 1%, were less diverse. Leading genera were Desmodesmus (Chodat) An et al., Navicula Bory, Scenedesmus Meyen, Monoraphidium Komárek.-Legn., Microcystis Lemmerm., Lagerheimia Chodat, Tetraedron Kütz., Amphora ex Kütz., Gomphonema Ehrenb. and Nitzschia Hassall. According to the cluster analysis results, the similarity of phytoplankton species composition on the sampling sites was 68–84%. During the investigation, blue-green algae: Aphanocapsa planctonica (G.M. Sm.) Komárek et Anagn., Anagnostidinema amphibium (C. Agardh ex Gomont) Strunecký, Bohunická, J.R. Johansen et Komárek, Merismopedia warmingiana Lagerh., M. tenuissima Lemmerm. Microcystis wesenbergii (Komárek) Komárek, dominated testifying the unsatisfactory state of the water body.
