In April to October 2009-2011, the species composition and seasonal changes in abundance and biomass of heterotrophic nanoflagellates were studied in the Sheksna River and in the small Yagorba and Serovka rivers running through a large industrial center. A total of 48 species and forms of colorless flagellates were recorded in the rivers. The abundance and biomass of heterotrophic nanoflagellates (average for 3 years) were 5788 cells/mL and 251.5 mg/m, correspondingly, in the Yagorba River; 6164 cells/mL and 266.2 mg/m in the Serovka River; and 4450 cells/mL and 193.5 mg/m, correspondingly, in the littoral zone of the Sheksna River. The maximal values (10.1-11.6 thousand cells/mL and 591-654 mg/m) were more frequently recorded in the second half of summer. A high positive correlation was observed between the biomass of single bacterial cells and heterotrophic nanoflagellates. In 2010, in all rivers with extremely high water temperatures, the abundance and biomass of heterotrophic nanoflagellates in summer was significantly higher than in other years.
