This article or the following section is not adequately provided with supporting documents ( e.g. individual evidence ). Information without sufficient evidence could be removed soon. Please help Wikipedia by researching the information and including good evidence.

The Alte Bockgraben is the old river bed of the Thaya in Lower Austria .

In the course of straightening the Thaya, its course was relocated to the Czech Republic . Since the Thaya also represented the state border, its former river bed took over this function, which is called Alter Bockgraben after one of its tributaries . At the same time, the Alte Bockgraben also takes in the right tributaries of the Thaya, including the Wildendürnbach , and routes them downstream to the Thaya. This depression on the Austrian side is flooded by the Thaya during a hundred-year flood.
