The measured level is below the published low-water reference for this stretch.

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.

Far below the 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 now33 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 15 October125 cm

On the record: For 2015–2025, we checked the eleven days around this date. Kaub’s lowest daily average was 29 cm, in 2018. Today’s reading is 33.
