The main objectives of this study are to reveal diversity of diatoms (Bacillariophyta), to analyze their community temporally and spatially and to assess the ecological status of Lake Palić based on the phytobenthos. High diatom taxa richness was found –105 taxa in total. In general, the dominant species are pollution-resistant and mostly tolerate high levels of organic pollution and nutrients. Two dominant taxa (Amphora pediculus and Gomphonema parvulum) were also the most frequent diatom taxa, recorded in all samples. Ecological status based on diatom indices values can be defined in a range from good (class II) to bad (class V) depending on the season and sampling site. The worst quality class (V – bad ecological status) is indicated by two indices (TID and TDI) created with the aim of determining the amount of nutrients. According to national legislation, the ecological status of Lake Palić can be characterized as good (class II) on the basis of phytobenthos. Only at second site in summer indicated a moderate status.
