Levels relevant to this sailing
Departing Monday 14 December 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.
One or more inputs are missing or stale. Those gauges show "no reading" below rather than a substituted value.
Your itinerary, by kind of water
- Day 1 Frankfurt In port
- Day 2 Main River Village Held by locks Main
- Day 3 Würzburg Held by locks Main
- Day 4 Bamberg Held by locks Main
- Day 5 Nuremberg Held by locks Main · Main-Danube Canal
- Day 6 Nuremberg In port
0 of 6 days on this itinerary sit on free-flowing water, where the level is the constraint. 4 are held by locks, and 2 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 Avalon Imagery II, using a draught of 1.60 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.

Main
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.
Mainz/Kostheim (Main-km 0) – Bamberg (Main-km 384)
Würzburg Main
154 cm rising 21 centimetres over 72 hours rising 21 cm over 72 hours
normal on mean low/high water (MNW/MHW) · normal on navigational reference levels (NSW/HSW) — the publisher's own classification of its own reading.
No official high-water mark is transcribed for this gauge from a source we have read, so none is shown. Read the authority's notices.

Würzburg's own forecast page — opens HND Bayern
Bavaria's own page for Würzburg on the Main, with the same choices as its Danube siblings: the measured level, and a two-day trend. The scale is centimetres over Würzburg's own gauge datum of 164,51 m NHN, which is the same datum this site's readings are on — the two pages printed 135 cm for the same quarter-hour when this link was checked. Nothing further ahead than two days is published for this gauge by anybody: BfG's six-week outlook does not reach the Main.
Waterlogged does not reproduce or interpret the values on this page. Bavaria's flood service asserts its own copyright over this presentation, so its forward figures are linked and never mirrored.

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 Avalon Waterways 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: yes, on the evidence read
- Confidence in that finding: confirmed
- Last checked: 2026-08-01
What we could not establish:
- No per-diem or numeric trigger threshold found anywhere in the fetched terms
- Whether the 1-year future-travel-credit has a dollar-value cap
- Which regional booking terms and ship-carrier contract govern the passenger's sailing
- Whether the facts meet the qualified 21-day force-majeure cash wording
- Avalon Waterways — official travel alerts and disruption page
- Avalon Waterways — published document we read (1)
- Avalon Waterways — published document we read (2)
- Avalon Waterways — published document we read (3)
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.
Request the Daily River Log Watch for this sailing. We keep the address only for that request: no marketing and no sale of the address. The morning email for a served sailing is sent each day until the morning after it ends; a sailing we do not serve sends nothing until we serve it. See Privacy for retention and deletion.
