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.

That product is BfG's six-week outlook. It is not a daily prediction. It shows likely ranges for each week. Each range is where that week's level is expected to fall, with the odds attached. The ranges come from many past-weather what-if runs, not from a single-line prediction.

Water levels are measured at the Kienstock gauge – Observation from Austria's government-owned waterway company for the Danube., provided through The European River Information Services portal. It republishes official river data from member countries..
What to check on the official page: No German federal product covers the Austrian Danube. Austria's own navigation service publishes a Kienstock page in English. Its graph also shows a forward series.
On that graph the measured line is labelled The German word on the Austrian graph for the measured water level.. The forward one is labelled The German word on the Austrian graph for the forward-looking values.. The forward values run several days ahead. Austria notes that Kienstock forecasts are meant for low-water situations.
Then stop looking for a target level, because there is not one. Austria publishes a An Austrian low-water reference level. It gives no depth a ship can use. figure for Kienstock but no A depth an authority aims to keep available for ships along a stretch. figure to pair with it. A level without a depth cannot be turned into a target for your ship, and we will not invent one.
What you can read is the direction of change. You also know that locks keep this stretch full anyway.

The measured level is under half of Waterlogged's reference line for this ship.
48 cm below Waterlogged’s estimated level

Don't be surprised by a negative number: the gauge's zero point sits above the riverbed, so readings below zero are real measurements, not errors.

What the statuses mean — each one is measured against the level we estimate this ship needs
- Far below the lineThe measured level is under half of Waterlogged's reference line for this ship.
- Below the lineThe measured level is below Waterlogged's reference line for this ship.
- Above the lineThe measured level is at or above Waterlogged's reference line for this ship.
- 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 line publishedThis is a real reading. There is nothing published to measure it against.
- No reading yetWe watch a gauge on this stretch. No current reading is on file for it.
- 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.
- Not sailingThe ship does not sail on this day. Your itinerary spends it on land, so no river level applies to it.

Each is drawn at its own town's coordinate, which can sit close to the port it serves. Each stretch is coloured by the worst port on it. A gauge level is not the depth of the The navigable channel where ships are meant to pass., not the room under your ship's keel, and not your ship's How deep a ship sits in the water. That depth sets how much water it needs underneath..
