Abstract:	The presence of toxic cyanobacterial blooms has been frequently reported in natural and artificial water bodies from different regions of the world. The toxic compounds (mainly hepatoand neurotoxins) produced by a number of cyanobacterial species have caused severe problems for animals and humans. Studies were carried out in the Kociewskie District on Lakes Słone, Czarne Południowe, and Kałębie, which are used for recreational purposes. Based on microscopic analyses the most frequently occurring cyanobacterial species were determined in samples collected every ten days from May until the end of September, 2004. They belonged to the genera: Pseudanabaena, Phormidium, Woronichinia, Planktothrix, and Anabaena. Picoplankton cyanobacteria were also recorded in the samples. HPLC was used to identify and quantify cyanobacterial toxins present in the lakes. In each lake microcystin-RR and -LR were found. The highest concentrations of Mcyst-RR measured in Lakes Słone, Czarne Południowe and Kałębie amounted to 6.65, 14.5, and 20.2 μg l^-1, respectively. Mcyst-LR was present only in trace amounts.
