Levels relevant to this sailing
Departing Thursday 17 September 2026.
This page does not say whether your cruise will run. It shows what the rivers on your route are reading now, how far that sits from the water a ship of this size needs, which of your days are level-sensitive at all, and where to read the authority's and the operator's own pages.
Your itinerary, by kind of water
- Day 1 Berlin In port
- Day 2 Berlin In port
- Day 3 Potsdam; Wittenberg Free-flowing Elbe
- Day 4 Wittenberg In port
- Day 5 Meissen Free-flowing Elbe
- Day 6 Dresden Free-flowing Elbe
- Day 7 Bad Schandau Free-flowing Elbe
- Day 8 Děčín; Prague Free-flowing Elbe
- Day 9 Prague In port
- Day 10 Prague In port
5 of 10 days on this itinerary sit on free-flowing water, where the level is the constraint. 0 are held by locks, and 5 are alongside.
These chips describe the kind of water each day sits on — geography, not a forecast and not a judgment about your sailing. A day held by locks does not care about a drought upstream; a free-flowing day is where the level is the constraint.
The corridors this itinerary crosses
Waterlogged hull clear-line for Viking Astrild, using a draught of 1.45 m. 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.

Elbe
Free-flowingThe river runs free here, so the level is the constraint: this is where a drought actually binds a hull.

low on mean low/high water (MNW/MHW) · normal on navigational reference levels (NSW/HSW) — the publisher's own classification of its own reading.
78 cm below the 130 cm calibrated judgment line. Waterlogged hull clear-line for Viking Astrild, using a draught of 1.45 m. 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.
Official sources and forecasts for Elbe
-
Elbe gauges and their forecasts — opens Saxony's state flood centre
Saxony's own list of Elbe gauges from the Czech border downstream. Every page shows the measured record, and where the centre forecasts that gauge a forecast table sits beside it.
Waterlogged does not reproduce or interpret the values on this page. The Saxon centre publishes these values as its own unchecked raw data and asserts its own copyright, so its forward figures are linked and never mirrored.
-
Official German federal six-week outlook (weekly means) — opens BfG
BfG publishes this as a trend statement in weekly means, six weeks ahead, not as day-by-day cruise guidance. It reaches Maxau, Kaub and Cologne on the Rhine, Pfelling and Hofkirchen on the Danube, and Dresden on the Elbe. Open the official product to read BfG's own figures and caveats.
This product is CC BY 4.0. Waterlogged may show the weekly means with the exact credit “Bundesanstalt für Gewässerkunde (BfG)” and the forecast's own issue date and time from the CSV header. We do not turn weekly means into per-day levels or passenger chances.

ELWIS — German federal waterways notices and navigation information
The official notices channel for commercial navigation on the German waterways: closures, lock works and high-water restrictions in the authority's own wording. Its gauge pages also show the forecast for that gauge where a German authority publishes one, and leave the forecast column empty where none exists.
ELWIS content is OpenData. Commercial reuse is allowed only when the content is unchanged and credited “www.elwis.de”; ELWIS's own terms also permit links to its pages, as long as the source and the address “www.elwis.de” are named. Waterlogged may show a short quote word for word with that credit and a link. A paraphrase counts as an alteration, so we never rewrite notice content in our own words.

What Viking publishes
Waterlogged does not interpret your contract and does not calculate what you may be owed. These are the operator's own pages and the dated facts we could establish about them.
- Named disruption programme found: not found in the documents read
- Terms differ by booking market: not established
- Confidence in that finding: confirmed
- Last checked: 2026-07-30
What we could not establish:
- Whether the separate 'US Ports' version of the Passenger Ticket Contract (referenced but not fetched) differs materially for cruises touching a US port
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.
Four questions worth asking your operator or agent:
- Which dated regional contract and disruption-program version applies to my booking?
- What does that document say for this specific itinerary change, and who decides whether it applies?
- What are the consequences if I cancel or reject a proposed change before the operator acts?
- What notice, evidence and deadline does the current document require, and where must it be sent?
Tell me when a gauge crosses a number
An alert here is a measured centimetre crossing on a named gauge — never a score, a probability or a changed opinion.
