The aim of this study was to assess the species assemblage of dragonflies of three chosen oxbow lakes of the Vistula river within the borders of Warsaw. There were: Gocławskie Lake, Powsinkowskie Lake and Wilanowskie Lake. The inventory of Odonata was conducted from May to October 2010. In overall, 24 species of Odonata were recorded. Most of them are considered to be common or very common in Poland. It was observed that the less surroundings of the lake were altered by human the more dragonflies from Siberian and West Siberian faunal elements were recorded. Due to the fact that researches were conducted only on three lakes this observations do not authorize us to state general conclusions about influence of urbanization on species assemblage of dragonflies. Authors are going to study this issue in further researches.
