Lake Vištytis (Lithuanian: Vištyčio ežeras, German: Wystiter See, Russian: Виштынецкое озеро) is a lake on the border between Lithuania (Vilkaviškis district) and Russia (Kaliningrad Oblast). Prior to World War II it marked part of the border between Germany (East Prussia) and Lithuania.
The small Lithuanian town of Vištytis on the northern shore was named after the lake. On the Lithuanian side, the lake and its environs are protected by Vištytis Regional Park. The lake has 15 inflows, but only one river, the Pissa, tributary to Pregolya, flows from this lake.[3]
Lake Vištytis covers an area of 17.83 km2 (6.88 sq mi), of which 5.44 km2 (2.10 sq mi) belongs to Lithuania.[2] This is a marked increase over 0.4 km2 (0.15 sq mi) that belonged to Lithuania before ratification of the Russian–Lithuanian border treaty in 2003.[4] On few occasions, high wind or broken equipment forced tourist boats to the opposite shore.[5][6] While unintentional, such incidents constitute illegal border crossing and can lead to sanctions from the border guards.[5] Sometimes the lake is used for smuggling goods, usually cigarettes, across the border.[7]
