The main purpose of this study was to determine the water quality parameters, phytoplankton composition and their seasonal variation in the Lake Sławskie. Samples for water quality analyses were collected once amonth in the years 2010–2011. According to physico-chemical parameters the ecological status of the Lake Sławskie was moderate. The lake is characterized by thermal and oxygen stratification within a period of summer. Among mineral forms of nitrogen an ammonium nitrogen dominated. In the case of ammonium nitrogen the maximum concentration reached 3.45 mg N-NH₄ l⁻¹ in summer 2010 (near the bottom). In winter and early spring periods the participation of nitrate nitrogen increased. Its maximum concentration was noted in February 2010 (1.58 mg N-NO₃ l⁻¹). Participation of nitrite nitrogen in water was low. The concentrations of dissolved phosphates and total phosphorus reached 0.53 mg P l⁻¹ and 0.61 mg P l⁻¹ near the bottom layer in the summer 2010, respectively. The qualitative and quantitative structure of phytoplankton were analyzed. The number of algae ranged from 100 org. ml⁻¹ to 23.1 · 10³ org. ml⁻¹. Domination of cryptophytes, chrysophytes, diatoms, chlorophytes and dinophytes were noted.
