Hydrology

The hydrology of Lake Mamry is complex, with the lake being fed by several rivers and streams, including the Węgorapa River and the Guber River, which flow into the lake from the surrounding catchment area, which includes parts of the Warmian-Masurian Voivodeship and the Podlaskie Voivodeship. The lake's outflow is via the Angrapa River and the Pregolya River, which flow into the Vistula Lagoon and eventually into the Baltic Sea, passing through the Elbląg Canal and the Vistula River. The lake's water level is regulated by a system of dams and locks, which help to control the flow of water and prevent flooding in the surrounding area, with the nearby Włocławek Reservoir and Siemanówka Reservoir also playing a crucial role in the region's hydrology.
