We hold no map coordinates for this sailing’s ports, so no map is drawn for it — an empty picture of the wrong rivers would say less than nothing. Every port on this sailing, and its water, is listed below.
Amsterdam
Day 1 · Monday 7 September · Netherlands
The ship is in port on this day. Our record holds no river transit for it, so there is no stretch of river to read.

Utrecht
Day 2 · Tuesday 8 September · Belgium
Locks hold this water at a working level, so low water is far less likely to affect this stretch. Other things still can.
Held by locks
Locks hold this level, so low water rarely stops a ship here. High water, maintenance, a closure, a restriction or the cruise line's own decision still can.
Low water does not close this stretch of river; a lock failure or a flood would. High water, maintenance, a closure or a restriction on the locks can still affect a day here, and so can the cruise line's own decision.
What to check on the official page: No water-level product applies to this day. This water is held at a working level by locks, so there is no gauge reading that would change your day.
What can affect a day like this is a lock outage or maintenance closure. That is announced through ELWIS, the official notices-to-skippers channel — in the authority's own words, before anyone else repeats them.
For this day, check the official notices rather than the levels.

Day 3 · Wednesday 9 September · Germany
The measured level is below the published low-water reference for this stretch.
63 cm below the published low-water reference
That is how far today's measured level sits below the published low-water reference for this stretch — the waterway authority’s own figure, not ours and not the cruise line's.

On the record: For 2015–2025, we checked the eleven days around this date. Koeln’s lowest daily average was 113 cm, in 2022. Today’s reading is 76. That is below every one of the 121 readings in that window.
Water levels are measured at the Köln gauge – German federal waterways gauge service (PEGELONLINE).

Ruedesheim
Day 5 · Friday 11 September · Germany
The measured level is under half of Waterlogged's reference line for this ship.
62 cm below Waterlogged’s reference line

| Water level now | 31 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 11 September | 143 cm |
On the record: For 2015–2025, we checked the eleven days around this date. Kaub’s lowest daily average was 68 cm, in 2022. Today’s reading is 31. That is below every one of the 121 readings in that window.

Water levels are measured at the Maxau gauge – German federal waterways gauge service (PEGELONLINE).
Your call here is 6 days away — beyond this forecast's reach
What to check on the official page: BfG does not forecast Maxau. Its daily fourteen-day product covers seven Rhine gauges further downstream, and Maxau is not one of them. The service that does forecast this gauge is Baden-Württemberg's own flood forecast centre, and ELWIS sends you there too.
On that page choose the Vorhersage tab. A solid line runs about two days ahead in centimetres. After that the chart switches to a wider trend estimate with a shaded band around it and a no-rain scenario, reaching roughly a fortnight.
Nothing on that page reaches 13 September yet. The forecast line stops about two days out, and the trend estimate past it is a range, not a date. Come back nearer the day.
Whichever line you read, it is the authority's, not ours. Waterlogged reports measured levels and the record behind them, and publishes no forward level of its own.
