VÁH / Vág / Waag. A left-side tributary of the Danube, the Váh has two headstreams. The Biely Váh (White Váh) rises in the Zelené pleso Kriváňske in the High Tatras and takes on the waters of the Mlynica stream; the Čierny Váh (Black Váh) takes its source in the Nízke Tatry at Král'ova hol'a. The united headstreams become the Váh and are joined by the Belá river at Liptovský Hrádok. The river then describes arcs to the west in the Liptovská kotlina and takes on the Orava, then flows through the gorge at Kral'ovany, the Turčianska kotlina, the Malá Fatra gorge, and the breathtaking Strečno gorge to reach Žilina. There it bends southwest, and reaches the plains at Trenčín, to bend southwards again. It enters the Little Danube, and is then named Váh-Danube, takes on the Nitra river, and finally enters the Danube at Komárno. The Váh stretches over 375 km. It has always been an important natural transportation route. Its lower course is navigable but its rapid and steeply falling upper course was also used for flotage and rafting. Although there had been plans for the regulation of its course, work on it began only in the late 19th century. Since then numerous training banks and storage lakes have been constructed always with an eye to the needs of agriculture, flood-prevention, navigation and industrial energy production. It is worth noting that the look of the Váh valley has been changed to a great extent since the time it was depicted by Thomas Ender.
