Abstract: The diversity of plankton assemblages from Lake Niegocin was studied from 1991 to 2001. Lake Niegocin is a eutrophic, dimictic lake in the Mazurian Lake District of Poland. The level of sewage contamination discharged into the lake from the city of Giżycko has decreased since 1994 when a new level biological sewage treatment facility became operational. A characteristic combination of species can be used to evaluate changes in the composition of phytoplankton assemblages caused by environmental changes. Significant, stable changes in the dominant and subdominant species were not observed until 1999, when the level of nutrients in the lake began to rise again.
