Austria is served by the Danube over a total distance of 329km (km 2201.75 to 1872.70) of which 20.2km is shared with Germany at the upstream end and 7.5km with the Slovak Republic at the downstream end.

However, free-flow conditions prevail downstream of Melk for about 40km, and below the last Austrian lock at Vienna Freudenau.

It is a former arm of the river, hemmed in between attractive stone quays through the city. It is entered on the right bank at km 1933.70, through Nussdorf lock, and rejoins the Danube at km 1919.40.
