With almost ten thousand closed bodies of water covering more than one hectare (2.47 acres) each, Poland has one of the highest numbers of lakes in the world. In Europe, only Finland has a greater density of lakes. The largest lakes, covering more than 100 square kilometres (39 sq mi), are Lake Sniardwy and Lake Mamry in Masuria, as well as Lake Lebsko and Lake Drawsko in Pomerania. In addition to the lake districts in the north (in Masuria, Pomerania, Kashubia, Lubuskie, and Greater Poland), there is also a large number of mountain lakes in the Tatras, of which the Morskie Oko is the largest in area. The lake with the greatest depth—of more than 100 metres (330 ft)—is Lake Hancza in the Wigry Lake District, east of Masuria in Podlaskie Voivodship.
