DREWENZ, a river of Germany, a right-bank tributary of the Vistula. It rises on the plateau of Hohenstein in East Prussia, 5 m. S.W. of the town of Hohenstein. After passing through the lake of Drewenz (7 m. long), it flows S.W. through flat marshy country, and forms, from just below the town of Strassburg to that of Leibitsch, a distance of 30 m., the frontier between Prussia and Russian Poland. After a course of 148 m. it enters the Vistula from the right, a little above the fortress of Thorn. It is navigable only for rafts. Lake Drewenz is connected with Elbing (and so with the Baltic) by the navigable Elbing-Oberland Canal.
