Cruise line
Viking River Cruises
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 Viking River Cruises, and no cruise line uses a Waterlogged clear-line operationally.
Which ship
Waterlogged class clear-line, using an assumed class draught of 1.45 m. 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.

Read the band, not the middle of it.

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.

Gironde Tidal
Tidal water. A single gauge height is a tide phase, not a river recession, and under-keel clearance here is a port question.

Dutch & Belgian waterways Notice-governed
Governed by the waterway authority's notices. Lock availability, dredging, agreed channel depths and temporary restrictions decide this stretch, not a drought reading.
One panel cannot describe this: the Waal runs free, the connecting canals are managed, and the Scheldt is tidal. Until the reach is split, treat it as notice-governed.

Operator policies change without notice and differ by booking market and contract version. Waterlogged does not calculate your refund, credit, hotel entitlement or insurance payout, and does not determine cancellation rights or legal remedies. Read the operator's own documents and the terms attached to your booking, and do not cancel pre-emptively on the strength of river data alone.
Linking is not endorsement. The publisher controls its own page, its own values and its own terms. Cruise-line names identify the operator's own documents and remain the property of their owners.
