ABSTRACT
The present work deals with water quality parameters and hydrobiology of Lake Ilmenskoe which is located at Ilmensky Reserve, Russia. We studied the physicochemical parameters (water and air temperature, pH, conductivity, dissolved oxygen and carbon dioxide, nitrates, nitrites, ammonia, phosphates, chlorides, bicarbonates, calcium, magnesium and organic matter) and phytoplankton in June-July during 2006 – 2012. A total of 68 taxa belonging to 7 divisions have been identified, including Bacillariophyta (28% of taxa), Chlorophyta (28%), Cyanophita (27%), Euglenophita (9%), Dinophyta (4%), Chrynosophita (3%), and Xanthophyta (1%). The 13 species of Mollusca and 9 species of Macrophytes were also observed. The values of the physicochemical parameters of water and taxonomic resolution obtained in the study sites indicate the mezotrophic status of the lake.

Keywords: Lake, Physico-Chemical Parameters, Phytoplankton, Taxonomy, Macrophytes
