The results of studies of hydrochemical indicators of the ecological state of floodplain water bodies in the middle reaches of the river are presented. Don located in the Ramonsky district of the Voronezh region. The features in the seasonal dynamics of the main hydrochemical characteristics of floodplain lakes are shown, taking into account the change in the water level in the Don River. Revealed the dependence of a number of indicators on the meteorological features of the year. In the studied lakes, an increase in permanganate oxidizability, BOD5, the content of ammonium and nitrate nitrogen, and a decrease in the content of dissolved oxygen.

Keywords:floodplain, floodplain lakes, oxbow, surface waters, hydrochemical indicators, overgrowth of floodplain lakes.
