The lakeside is under protection, and buildings are not allowed, resulting in reed bed and a rich fauna and flora: Around 400 plant species in the lake and 19 species in its tributaries. The nature reserves are important for the birds breeding there including more than 120 migratory species. Due to the high population density and extensive agricultural use of the region around the lake, water was in a very strong phosphorus concentrations determining the diversity of species resulting in growing algal and stench. Since 1970, by ventilation and reduction of phosphate, the situation was markedly improved.[1]
