淡水河
The Tamsui River begins at the confluence of Xindian River and Dahan River at the western boundary of Taipei and New Taipei City, just north of Banqiao District, and flows northward and northwestward, passing the eponymous Tamsui District, then emptying into the Taiwan Strait. Formerly known as the "Dolatok River", it is one of the few rivers in the island that flows along a north–south direction.
