Lake Synevyr. 29/07/04; Zakarpatska Oblast; 29 ha; 48°37'N 023°41'E. National Park. Located among spruce forests, Lake Synevyr, though small, is the largest natural water body in the Ukrainian Carpathians. Three permanent mountain streams flow into the lake, causing accelerated silting in those places and transforming into eutrophic mires overgrown by Glyceria fluitans and Equisetum palustre. The Noble Crayfish Astacus astacus and flora species listed in the Red Data Book of Ukraine are registered within the site. Floating vegetation communities of the lake are represented by different species of Potamogeton and littoral-water communities by stands of Glyceria fluitans, Equisetum palustre, Mentha piperita. The lake, associated with legends and widely popular among local people, is a symbol of the Ukrainian Carpathians and represents a great environmental and educational value. Human activities include regulated recreation, scientific research and nature conservation. Ramsar site no. 1400. Most recent RIS information: 2003.
