Absheron Peninsula has a number of small lakes rich in algoflora along with water plants.The study was performed in contaminated lakes of the Absheron Peninsula. Algal studies were performed in these lakes in the 60- 80's years of the XX century. Algae of selected eight lakes (Khojahasan, Boyukshor, Zygh, Bulbula, Gyrmyzy, Binagadi, Gala, Lokbatan) were studied. Information and original studies of plankton algae in lakes, data on species diversity, ecology and distribution of the species are provided. Nomenclatural novelties were considered in the study. In total 76 species belonging to 33 genera, 24 families, 18 order and 7 classes were determined. The most common species for all lakes were Closterium parvulum Nägeli, Volvox globator Linnaeus, Cosmarium obtusatum Schmidle, Navicula pygmeae Kützing, Diatoma vulgare Bory, Nitzschia tryblionella Hantzsch. The study revealed that, Bulbula and Gala lakes were much diverse in species composition.
