The objective of our research was to determine the impact of water abstraction for hydroelectric power plant purposes Oljarica (River Kokra) and Niko (River Selška Sora) on phytobenthos community. Altogether, 52 taxa from six algal classes were determined in both rivers. According to the number of identified taxa, diatoms prevailed. Comparison of phytobenthos species compositions on both rivers before and after water abstraction showed that in the Selška Sora River phytobenthos biodiversity was lower below the dam while in both rivers decrease of algal taxa typical for unpolluted waters and increase of algal taxa typical for organically polluted waters were noticed. On both rivers, the values of Saprobic index were higher on the sites with water abstraction, which could be the result of increased organic load or reduced flow. Phytobenthos biomass in the Kokra River was the highest in the areas with low water level and low water velocity.
