The Thaya ( ) is a river in Central Europe, the longest tributary to the river Morava. Its drainage basin is . It is ( with its longest source river German Thaya) long and 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 (, ), flowing together at Raabs an der Thaya. The confluence of Thaya and Morava is the southernmost and the lowest point of Moravia. Its name means "the inert". There is also a small village which bears the name Dyje, located near Znojmo. Geography 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.
