Vistula (vĭsˈchŏlə) [key], Pol. Wisła, longest river and principal waterway of Poland, c.665 mi (1,070 km) long. It rises in the West Beskid range of the Carpathians, S Poland, and flows NE past Kraków, NW past Warsaw and Toruń, and N past Grudziądz and Tczew to the Gulf of Danzig on the Baltic Sea. The two main branches of its estuary are the Nogat, which flows past Malbork to the Vistula Lagoon, and the Martwa Wisła [dead Vistula], which flows past Gdańsk. Navigable for small craft for almost its entire length, the Vistula is connected by canals with the Oder, Dnieper, Neman, and Pregel rivers. Among its tributaries are the Dunajec, San, and Narew (with the Bug) rivers. Coal is transported from SW Poland, and lumber is logged along the lower Vistula.
