The Radoniqi Lake situated in the western part of Kosovo, is one of the largest lakes in the country and it supplies the city of Gjakova and some small settlements in the region with drinking water. Algological examination of the Radoniqi Lake was carried out with the aim to analyze the algal composition and quality of the lake water. The samples for qualitative and quantitative analysis were collected at 4 localities in the Radoniqi Lake during summer (month of July), 2002. The saprobiological analysis was done based on algal bioindicators. The presence of 137 algal taxa from 5 different divisions was established: Cyanophyta - 27, Bacillariophyta - 76, Euglenophyta - 12, Chlorophyta - 19, and Xanthophyta - 3. Algae from the Chlorophyta division were present in phytoplankton at all localities. A total of 28 algal bioindicators were identified. The values of Pantle-Buck’s saprobity index (saprobic valence) indicated that the Radoniqi Lake, during the month of July 2002 belonged to the β-mesosaprobic zone (II class of water quality).
