The Thaya (Czech: Dyje [ˈdɪjɛ]) is a riverinCentral Europe, the longest tributary to the river Morava. Its drainage basin is 12,772 km2 (4,931 sq mi).[2] Its length is 224 km (139 mi) (322 km (200 mi) with its longest source river German Thaya).[1] It meanders from west to east in the border area between Lower Austria (Austria) and South Moravia (Czech Republic), though the frontier does not exactly follow the river's course in most parts. Its source is in two smaller rivers, namely the German Thaya (Deutsche Thaya) and the Moravian Thaya (Czech: Moravská Dyje, German: Mährische Thaya), flowing togetheratRaabs an der Thaya.
The confluence of Thaya and Morava is the southernmost and the lowest pointofMoravia.
Its name means "the inert". There is also a small village which bears the name Dyje, located near Znojmo.
In its upper reaches, the Thaya flows through deep gorges (Podyjí), along which it passes many castles and chateaus. In Moravia, it has been dammed in several locations.
Thaya gathers waters from the western half of Moravia and the adjacent part of Lower Austria. Its biggest tributaries are Svratka and Jihlava, flowing together into the middle one of the Nové Mlýny reservoirs.
Important cities and towns along the Thaya:
All the dams are situated in Czech Republic. They are used for irrigation, hydroelectricity and flood protection.
