Kamencové Lake (also called Alum Lake) located in Chomutov (North Bohemian Brown Coal Basin, Czech Republic) is a worldwide unique for its lake water chemical composition (K Al (SO4)2 12 H2O) that naturally prevents algae growth. The region used to be a centre of heavy industry based on brown coal burning, with a crucial impact on the environment (especially acid rain) in 1980s. This fact was considered the key aspect influencing the lake water quality deterioration in the past, besides the growing popularity of the area for recreational purposes (increased risk of eutrophication) and the significant changes in the lake maintenance (increased risk of eutrophication, excessive bottom sedimentation). Due to the real threat of gradual losing the lake water unique characteristics, scientifically-based systematic measures reducing the potential risk of eutrophication need to be implemented. The present study builds on the results of previous surveys by Geofyzika Brno, Povodí Ohře, s.p. or Hydroprojekt Praha. Its aim is to assess the potential risk of eutrophication in Alum Lake and to propose remedial measures.
