  Maintenance dredging is currently performed in the area of the shallow section.

* "Deep channel" refers to that area of the marked fairway which has the width required for a 4-unit convoy travelling downstream. The respective width of the fairway is dependent on the river bend radii involved. Accordingly, passing and overtaking within the confines of the deep channel is generally not possible. When necessary, and in accordance with Articles 6.04, 6.05 and 6.10 of the Waterway Traffic Act, vessels should wait at a suitable location until it is possible to proceed through a shallow area using the deep channel of the main fairway.
Information on the course of the deep channel is available in the area map for the respective shallow section. The course of the fairway is indicated by buoyage and marking.
The published minimum fairway depths are calculated on the current water levels available every quarter of an hour at the respective reference gauging station and are thus updated every 15 minutes. Information concerning the respective reference gauge is available in the area map for the shallow section (PDF).
At shallow sections in the free-flowing Danube of the Wachau valley and east of Vienna water depths are monitored on a monthly basis. As the riverbed in free-flowing sections of the river is constantly changing, the data provided relating to water depths should be regarded purely as a snapshot of current conditions. No liability can therefore be assumed for their accuracy at the time of the request for information.
