Waters
Numerous lakes and small water basins are remnants of the glaciation periods. They have various shapes, areas and depth. The Park is a site of 42 lakes, the largest being Wigry Lake of 2,187 ha of area and up to 73 m in depth. It occupies the central part of the Park. Lakes represent different limnological types and vary in terms of productivity, thermal stratification, and concentration of humus compounds. Particularly interesting are small dystrophic lakes situated within the forests, surrounded by peatmoss communities, called "suchary". The main river of the Park is the Czarna Hancza, which is also a well know canoeing route.
