02.03.1 Degree of Eutrophisation 1993-1995

The quality classes are presented by water segment. The quality classification is carried out on dammed plankton-dominated streams. It is based on the mean chlorophyll-a content over three years, for the period from 1 March to 31 October (LAWA 1996), as well as on the expected visibility depth ranges and overall phosphorus concentrations (Leibniz Institute of Freshwater Ecology and Inland Fisheries, IGB). 02.03.1 Degree of Eutrophisation 1993-1995
