Barje reservoir, established by damming of Veternica river, 30 km upstream from Leskovac town (Serbia), was intended for water supply of communities of Leskovac and Lebane. From its final formation and attaining of maximal volume (1995), long-year investigations have performed, and they included morphometric, chemical and biological parameters (phytoplankton, zooplankton, benthic fauna and ichthiofauna). The results of these hydrobiological investigations have showed that the reservoir Barje is unstable. In according to recommendation for continual following of condition of Barje reservoir, investigations of phytoplankton were repeated in spring and autumn aspects in 2005, and quality of the water was determined on the base of algae. The results of saprobiotic investigations show that the type of water is oligo-beta saprobic, but dense populations of eutrophic species (Fragilaria crotonensis and Closterium aciculare) indicate on deterioration of trophic conditions in this reservoir.
