This reissue of '2W7D Edition 22' of the Inland ENCs (topographical and shipping police data) is based on the Inland ECDIS Standard 2.5. The Inland ENCs for the common border section between Austria and Germany can be downloaded here.

Reliable depth information is provided by the bathymetric IENC layer with the file name "2WBD....". The bathymetric IENCs "2WBD"  contain depth data for the entire Austrian Danube and the common border section between Austria and Germany (river km 2223.2 - km 1872.7) based on the Inland ECDIS Standard 2.5.

Information on the recommended tracks in the Austrian Inland ENCs

In the Austrian inland ENCs, a "recommended track" is indicated, which represents the center line of the course of the deep channel published by viadonau in the location maps for currently relevant shallow areas in the two free-flowing sections of the Danube (Wachau and east of Vienna). "Deep channel" refers to that area of the marked fairway which, based on current riverbed measurements, shows the greatest navigable depths at regulation low water level (RNW 2020) and 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 (between 40 and 80 meters). 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.
