On August 14, 2026, the water level at the Kaub gauge on the Middle Rhine fell to approximately 10 centimetres, marking an unprecedented low that surpassed the previous record set in 2018. Subsequent measurements after this date showed continued decline, confirming critical navigation challenges on the Rhine River amid persistent heat and drought across Europe.
The extremely shallow water conditions near Kaub have made this section of the Rhine unnavigable for many vessels, causing significant interruption to commercial shipping. German shipping organisations warned the Rhine may divide into navigable and non-navigable stretches if water levels continue to drop, further disrupting
freight operations. Freight vessels still able to travel on the river are operating with notably reduced cargo loads, increasing the transfer of goods to road and rail networks and adding strain to European logistics.
River cruise companies have taken various measures in response to the low water levels and resulting navigation barriers. Riviera Travel cancelled 10 scheduled departures and altered six itineraries across the Rhine, Danube, Moselle, and Main rivers. Alternatives implemented by Riviera Travel included modifying routes, substituting vessels, and outright cancellations. Uniworld has also substituted ships specifically on affected Rhine itineraries. Other operators employed ship swaps, coach transfers,
and changes to embarkation or disembarkation points to manage operational difficulties caused by the drought.
The impact on river cruise passengers varies depending on the vessel’s position, draft, and ability to navigate affected river sections. Some cruises continue despite severe conditions in other areas, while others require passengers to switch ships or use land-based transport. Planned stops may be missed or altered depending on changing water depths and navigation feasibility along the Rhine and adjacent waterways.
European river cruise companies remain closely monitoring river gauges and weather forecasts, especially at critical bottlenecks like Kaub. Decisions about the viability of further
departures later in August and beyond hinge on these observations amid ongoing drought conditions that continue to complicate navigation and scheduling on the Rhine and other major rivers.
