The work was carried out within the project “Algae-flora of lake systems of Kokshetau-Borovoye, development of the recommendations about fighting against species of micro- and macro-algae causing oozing and “blossoming” of ponds in mass people recreation zones”. Sample collecting was made during the expedition trips at summer season from the lakes Akkol, Lebedinoye and from the several region lakes such as Borovoye, Schuchiye, Bolshoye and Maloye Chebachye, Lebiyazhiye, Maybalyk, Katarkol and Shalkar. As a result of cameral processing and preliminary identification of the collected material more than 231 alga species were defined: Bacillariophyta – 151; Chlorophyta – 46; Cyanophyta – 16, Dinophyta – 4; Charophyta – 6; Euglenophyta – 7 and Chrysophyta – 1. Alga species and their distribution by systematic groups were determined. They belong to 71 genera, 39 families, 24 orders, 11 classes and 7 departments. The greatest species variety was belonged to Bacillariophyta and Chlorophyta alga species. Often seen, dominating and causing water “blossoming” alga species of all departments were revealed in lakes Akkol and Bolshoye Chebachye. Mass development was demonstrated by the species Anabaena flos-aquae Breb. ex Born. et Flah. and species of the genus Oscillatoria Vauch. ex Gom. On the stones there were revealed mucilaginous yellow-brown fouling of Bacillariophyta algae such as Gomphonema, Synedra and Melosira. Reasons of mass development of the activators of blossoming and oozing of the ponds were revealed. They were caused by: increase of the content of nitrates, phosphates and other nutrients in the water; washouting the non-organic fertilizers from the nearest hills and fields; sedimentary waters coming into the ponds. The abstract and the biological description of the alga species (231 species of 7 departments) revealed in the lakes of the studied territories were made. Among found algae the perspective species of Chlorophyta and Charophyta algae for purification of the polluted waters were marked out.
