Abstract

Assessment of the ecological state of lakes as proposed by the Polish Limnological SocietyThe paper presents a method of assessment of the ecological state of lakes. It is based on methodology proposed by the Polish Limnological Society. According to this methodology, a set of indicators may be determined and may serve as a basis to make recommendations on what actions should be taken to maintain or restore a good ecological state of a lake. The set of indicators used for remedy recommendations includes: environmental pressure indicators that determine the rate of eutrophication in bodies of water, indicators of the state of the environment describing water quality and the balance of the water resources of a lake, and reaction indicators providing information on the degree of eutrophication of a lake.
