Conditions of the cyanobacterial development in lakes Kotokelskoe and Dikoe were in- vestigated. Previously these lakes were productive reservoirs of Zabaikalia. Currently as a result of natural and anthropogenic processes the lakes lost fisheries and recreational val- ue. The close location of investigated lakes to Lake Baikal has a direct effect on its func- tion. In the summer time favorable conditions for active development of cyanobacteria are created in the lakes. 9 species of cyanobacteria were identified. The dominating species both in the samples of lake Dikoe and lake Kotokelskoe was M. aeruginosa, a potentially toxic species. According to the content of chlorophyll a the investigated lakes were oligo- trophic and mesotrophic water bodies.
