 abstract={Studies were done in winter 1996 in three ice-covered dimictic lakes of the Łęczna-Włodawa Lakeland, eastern Poland. They involved physico-chemical conditions (temperature, oxygen concentration, pH, conductivity and Secchi-disc transparency), as well as biological ones (abundance, chlorophyll a concentration and phytoplankton structure). The oxygenation of the near-bottom layers combined with the observed structure of the winter phytoplankton confirm the rate of eutrophication of these bodies of water which had already been observed in the summer.},
