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.

The measured level is under half of Waterlogged's reference line for a ship of this class.
63 cm below Waterlogged’s reference line

| 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 21 November | 149 cm |
On the record: For 2015–2025, we checked the eleven days around this date. Kaub’s lowest daily average was 28 cm, in 2018. Today’s reading is 30.

- Far below the lineThe measured level is under half of Waterlogged's reference line for a ship of this class.
- Below the lineThe measured level is below Waterlogged's reference line for a ship of this class.
- Above the lineThe measured level is at or above Waterlogged's reference line for a ship of this class.
- Lock-controlledLocks hold this water at a working level, so low water is far less likely to affect this stretch. Other things still can.

- No gauge on this stretchWe watch no gauge on this stretch of river. There is no reading for this day and no line to measure one against.
- In portThe ship is in port on this day. Our record holds no river transit for it, so there is no stretch of river to read.
