Patterns of distribution and community structure of heterotrophic flagellates and bacterioplankton were investigated in the Vatinsky Yogan river (the Tyumen region). Low microbial abundance was recorded in the river. 38 species of heterotrophic flagellates from nine taxons and a group of uncertain taxonomic position were found in the river. The majority of them belonged to the consumers of bacteria and detritus. A positive correlation between the oil concentrations in water and in bottom sediments, on the one hand, and the abundance and biodiversity of heterotrophic flagellates, on the other hand, was established.
