The river's logbook for cruise travellers Waterlogged River Cruise Watch

European river levels for cruise travellers.

What the river is reading right now, how far that sits from the water a cruise ship needs, which way it has moved in the last 72 hours, and where to read the authority's own forecast.

Waterlogged does not predict whether a cruise will run. It shows you the measurements and names their limits, so you can ask your operator a better question.

The river right now

One card per corridor, typed by what actually governs it. A free-flowing stretch is level-limited, so it gets a clear-line and a gap in centimetres. A lock-held stretch is not, so it does not get one — it gets the high-water side, which is what closes it.

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. It is computed using an assumed 1.60 m draught unless you pick a cruise line below. See every gauge · the threshold diary · where the numbers come from.

By cruise line

Pick a line to see the corridors its ships use and the water on each of them today, against that line's hull or class draught assumption. No cruise line uses a Waterlogged clear-line, and none of them has endorsed this site.

Corridors we do not read a gauge on

The catalogue sails these, and Waterlogged has no licence-clear live feed or no defensible model for them yet. Rather than leave a gap, here is what governs each one and who publishes the authoritative information.

Official forecasts and notices

Waterlogged does not publish a river forecast. The authorities do, on their own sites, with their own caveats. Linking is not endorsement. The publisher controls its own page, its own values and its own terms.

  • Official German federal 14-day water-level forecast — opens BfG

    The German federal hydrology institute's own daily water-level forecast for the Rhine and other supported gauges, with BfG's own uncertainty ranges and caveats.

    Official external site — leaves Waterlogged. Published by Bundesanstalt für Gewässerkunde (BfG). Link checked 2026-08-02.

    Waterlogged does not reproduce or interpret the values on this page. BfG's catalogue metadata asserts CC BY 4.0 but the delivery channels carry no unambiguous grant, so Waterlogged links to the forecast rather than copying, dailyising or scoring its values.

  • 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.

    Official external site — leaves Waterlogged. Published by Wasserstraßen- und Schifffahrtsverwaltung des Bundes (WSV). Link checked 2026-08-02.

    Waterlogged does not reproduce or interpret the values on this page. Linking needs no licence; the notice text remains governed by the publisher's terms, so Waterlogged does not scrape it into a report.

  • hydroinfo.hu — Hungarian hydrological service (official Danube levels and notices)

    Hungary's official hydrological pages for the Danube, including Budapest.

    Official external site — leaves Waterlogged. Published by Országos Vízügyi Főigazgatóság (OVF). Link checked 2026-08-02.

    Waterlogged does not reproduce or interpret the values on this page. No written reuse permission is held. Waterlogged publishes no hydroinfo time series, day-of-year median, selected low year or fitted parameter on a customer page.

Rain in the next 14 days

Status: rain forecast not yet enabled. Waterlogged shows forecast precipitation only under a paid Open-Meteo commercial contract, and no contract key is configured on this deployment. The official services linked below publish their own rain forecasts.

Rain may slow a fall or create a rise after losses and routing. Waterlogged does not convert this forecast into gauge centimetres or a cruise-disruption probability.

Look up a sailing

Compose the same information for one itinerary: which corridors it crosses, which of its days are level-sensitive and which are held by locks, and the current gap on every free-flowing leg.

Choose your line, cruise and date. Cruise-specific scenarios and forecast updates are published daily for departures within the next three calendar months.

Where the numbers come from, and what we will not do

Official sources, named on every page

Live German readings come from PEGELONLINE, the German Federal Waterways and Shipping Administration's gauge service (DL-DE-Zero 2.0). Bavarian Danube long-history files come from GKD under CC BY 4.0: Datenquelle: Bayerisches Landesamt für Umwelt, www.lfu.bayern.de. Budapest and Kienstock are delivered through EuRIS Hydrometeo v3 with the required EuRIS attribution. Every live reading carries its measurement time, and a stale reading is flagged rather than quietly used. The full source matrix says what we render, what we only link, and what we withhold.

Official forecasts are linked, not copied

The German federal 14-day and six-week water-level forecasts are produced and hosted by the Bundesanstalt für Gewässerkunde. Their reuse basis is not established — the catalogue metadata says one thing and the delivery channel carries no grant — so Waterlogged links to them and shows none of their values. Nothing on this site is derived from them.

No climate projections — measured signal only

Nothing in this product is driven by a climate model run. Where history appears it is measured levels on measured dates, from an archive we name, and it is never converted into odds, chances or seasons that failed.

Measured fact and our own arithmetic, kept apart

A gauge reading is fact. A clear-line is our arithmetic over a published reference pair and a stated draught assumption. A judgment band is a judgment. Every number on this site says which of the three it is, because they are not the same kind of thing.

Not travel advice, and not a navigation product. Nothing here should be used to plan the movement of a vessel. Sources and method · what is live right now · what operators publish.
