Rhine water levels today

What the water is actually doing on the Rhine today, at the places a river cruise ship has to get through. Every number is a measurement that has already been taken.

Readings on this page were last measured 7 September.

The Rhine at Maxau

316 cm (measured 7 September)

Over the last 72 hours: falling 13 cm.

We publish no comparison line for this gauge. This reading is context for the reach rather than a figure to measure a ship against, and inventing a line to compare it with would be worse than saying so.

We do not draw a measured history graph for this gauge. The reading above is current and official; the archive the graph would be drawn from is not ours to republish.

Everything we hold on the Maxau gauge — its reading today, the same date in earlier years, and the authority that publishes it.

The Rhine at Kaub

33 cm (measured 7 September)

Over the last 72 hours: falling 10 cm.

How we calculate ship needWaterlogged estimates that a river needs to be 2.05m in depth to be navigable by river cruises. A river cruise ship has a draft of approximately 1.60m and we add an additional 0.45m above this. This number is not from official cruise line reports. Ships with smaller drafts or special permission may be able to sail in less water. The figure on the page beside this note is a gauge level, and a gauge level is the height of the water at one measuring station, read from that station's own zero. It is not the depth of the navigable channel, it is not the room left under a ship's keel, and it is not a ship's draft. Our line is a level we compare today's reading with. It is not a depth anybody has measured under your ship.: 93 cm. Today's reading is 60 cm below it.

The level it is measured against is our own estimate, not a figure from the cruise line. It is our line, plainly labelled, and it is not the operator's decision to sail.

The solid line is what this gauge has measured. The dashed line is the level normal for the date (median for 2015–2026). The dotted line is the comparison line above. Nothing here is a forecast.

The Rhine at Cologne

76 cm (measured 7 September)

Over the last 72 hours: falling 19 cm.

Published An authority's published low-level mark for a stretch. It is not a requirement for your ship. for this stretch: 139 cm. Today's reading is 63 cm below it.

What this means for your sailing

It means less than a cruise line would like you to think and more than a search result will tell you. A reading below the line we draw does not mean your cruise is cancelled, and a reading above it is not a promise that it will sail. Only the operator decides that.

Waterlogged does not provide a future river depth forecast. The trend and the graph describe measured moves that have already happened.

To see these gauges arranged against one particular sailing — the ports in order, the dates you are actually on the water — start from the front page and pick your cruise line, your cruise and your departure date.

Sailing more than one river? We watch the same way on the Danube, the Main, the Moselle and the Elbe.
