The Nogat is a 62 km long delta branch of the Vistula River and does not empty at Gdańsk Bay as the main river does.
The Nogat has its origin near the city of Biała Góra as an anabranch of the Vistula River. Shortly after the river Liwa flows into the Nogat. Than the river passes Malbork and winds NE towards Elbląg (but does not reach the city). NW of Elbląg the Nogat flows into the SW part of the Vistula Lagoon.
Historically the Nogat River divides East Prussia and West Prussia.
