Day 3 · Tuesday 10 November · Portugal
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.

What the statuses mean — each one is measured against the level we estimate a ship of this class needs
- 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 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.
The small white boards mark A riverside station that measures the water level in centimetres against a fixed zero point. stations — the places where a reading is physically taken. 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..
