Low water is making headlines again.

After an exceptionally hot, dry summer, portions of the Rhine and Danube have fallen to unusually low levels. Some cruise lines are changing ports, embarkation points and itineraries. Others are using motorcoaches or transferring guests between sister ships. A limited number of cruises have been cancelled.

If you have a river cruise approaching—or are considering booking one—those reports can be unsettling. But they require perspective.

In more than 50 European river cruises, I have never experienced a major disruption caused by either high or low water. Perhaps I have been lucky, but available cruise-line data also suggest that most departures operate without water-related problems. AmaWaterways estimates that high or low water affects approximately 3.5 percent of its European departures in an average year.

That doesn’t mean the risk should be ignored. It means we should understand what “affected” actually means.

A water-related change could be relatively minor, such as docking in a nearby town. It could involve a motorcoach transfer or a missed port. More substantially, passengers might change ships or spend part of the trip in hotels. Complete cancellation is possible, but considerably less common.

We also want to recognize the river cruise companies making current travel information accessible from their homepages. As of August 10, 2026, we found links from the U.S. homepages of AmaWaterways, Emerald Cruises, Scenic, Uniworld and Viking leading to travel alerts, current-sailing updates or other timely information for guests.

The links vary in prominence, and AmaWaterways deserves a particular shout-out for placing its travel advisory where visitors are especially likely to see it. Viking’s current-sailing page also specifically addresses exceptionally low water on portions of the Rhine and Danube.

We may have missed an operator, particularly where websites differ by country or display alerts dynamically. If you find another river cruise company providing current water-level information from its homepage, please let us know—we would be pleased to add it.

To help travelers separate the actual risk from the alarming headlines, we have thoroughly updated one of River Cruise Advisor’s most visited resources: European River Cruise Water Levels: What Travelers Need to Know

The updated guide explains:

• How frequently cruises are affected
• The difference between a minor change and a major disruption
• Which stretches of the Rhine, Danube and other rivers are most vulnerable
• When high and low water are most likely
• How ship swaps work
• Why ship design and fleet size matter
• What questions to ask before choosing a cruise line
• Why today’s water level cannot predict a cruise several months from now
• Whether you should cancel when you hear reports of difficult conditions

The page also includes firsthand reports from River Cruise Advisor readers. There are now more than 2,000 comments accumulated over the years—an unusually rich record of what travelers experienced and how cruise lines responded.

Those comments are valuable, but they also need context: People whose trips went badly are understandably more likely to post than those whose cruises operated normally.

We’ve also included one of my most memorable low-water experiences. In November 2015, I sailed the Rhine aboard AmaSerena during historic lows. Between Rüdesheim and Koblenz, AmaSerena was the only river cruiser I saw navigating a shallow stretch that had stopped many other ships. At one point, the ship had only about a foot of water beneath it—but it made it through.

Our bottom line remains simple: We would not let concern about water levels prevent us from taking a European river cruise. We would choose the cruise line carefully, understand how it handles disruptions, consider appropriate travel insurance—and go.

If you are currently cruising—or have recently returned—please add a comment with your river, route, cruise line, sailing date and what actually changed. Your firsthand report may help another traveler make a better-informed decision.

See you on the rivers.
