Cruise line
A-ROSA Flussschiff
Current water on the corridors this line's catalogue uses, compared with the level Waterlogged calculates a ship of this size wants.
Waterlogged is not affiliated with A-ROSA Flussschiff, and no cruise line uses a Waterlogged clear-line operationally.
Which ship
Waterlogged clear-line, using an assumed 1.60 m draught. Our catalogue holds no hull for this line's routes, so this is a class assumption — not a fact about your ship, and not a figure the operator has published for the vessel you will be on.
A Waterlogged clear-line is our own arithmetic: the gauge reading at which the published reference depth, minus the ship's draught and a fixed safety allowance, still leaves a comfortable margin. It is not an operator's decision rule and no cruise line uses it.
The water today
-
Austrian Danube
Held by locksLevel held by locks. Weirs keep a working depth through a drought, so the risk on this stretch is high water and lock operations — not low water.
Passau (Danube-km 2226) – Vienna (Danube-km 1929), except the Wachau (Melk–Krems, Danube-km 2036–2002)
Kienstock Danube
101 cm falling 7 centimetres over 72 hours falling 7 cm over 72 hours
500 cm below the 601 cm first high-water mark (speed and wash limits, and the room under the bridges starts to run out).
Held by the Austrian barrage chain above the Wachau and below it. The Wachau between them runs free and is listed on its own. Kienstock, the gauge shown here, stands in the Wachau, not on this water: its reading is not this stretch's level, and it is shown for its high-water marks, which close this stretch too.
Official sources and forecasts for Austrian Danube
-
viadonau / DoRIS — Kienstock gauge page with its forward view (English)
Austria's own page for the Wachau reference gauge. Its graph draws the measured line as “Pegel” and the forward line as “Vorschau”, running about five days ahead. Austria notes that Kienstock forecasts are meant for low-water situations. The same site holds the Austrian fairway information and river notices.
viadonau allows reuse of its Kienstock values with the credit “Quelle: viadonau”, and that credit rides on every Kienstock figure we show. Waterlogged still publishes no forward level of its own: the forward numbers on our Kienstock page are EuRIS's, under EuRIS's name, and this page is viadonau's own fuller version of the same gauge.

Vienna–Budapest Danube
Free-flowingThe river runs free here, so the level is the constraint: this is where a drought actually binds a hull.
Vienna (Danube-km 1929) – Budapest (Danube-km 1646)
Budapest Danube
3 cm rising 1 centimetres over 72 hours rising 1 cm over 72 hours
97 cm below the 100 cm calibrated judgment line. Waterlogged clear-line, using an assumed 1.60 m draught. A hand-set band, not a measured fairway depth and not worked out from any ship's draught. It is our judgment about this stretch and it is labelled as one.
