Green algae – especially "Chlorella" sp. – are present all over the lake except for the springcave and its surroundings. "Navicula cryptocephala" and "Navicula capitatoradiata "are common diatoms in the lake. The biodiversity of the phytoplankton is poor and its biomass is low, thus the lake's trophic level ranges from oligotrophic to mesotrophic.
