No line published

This is a real reading. There is nothing published to measure it against.

219 cm measured

Nothing is published for this stretch to measure the reading against.

Water level now219 cm
Normal for 3 October224 cm

Water levels are measured at the Cochem gauge – German federal waterways gauge service (PEGELONLINE).

What to check on the official page: No German federal forecast covers the Moselle. The state flood forecast centre for Rhineland-Palatinate is the one service that forecasts this gauge, and the button below opens Cochem's own page there.

Its own notice says a Cochem forecast is only possible above 241 cm, because weirs hold this water at a working level. Below that the chart shows a flat line rather than a forecast.

The risk this page is built for is high water, not low. For a day on this stretch, the thing to check is the notices — lock works and closures — rather than a level.

Day 6 · Monday 5 October · Germany

Far below the line

The measured level is under half of Waterlogged's reference line for this ship.

62 cm below Waterlogged’s reference line

That is how far today's measured level sits below the line we estimate this ship needs. The level it is measured against is our own estimate, not a figure from the cruise line.

Water level now31 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
Normal for 5 October128 cm

On the record: For 2015–2025, we checked the eleven days around this date. Kaub’s lowest daily average was 56 cm, in 2018. Today’s reading is 31. That is below every one of the 121 readings in that window.

Water levels are measured at the Kaub gauge – German federal waterways gauge service (PEGELONLINE).
