Record low water at Kaub restricts Rhine barge shipping
Record low water at Kaub restricts Rhine barge shipping. The disruption ran from 2026-08-01 (August 2026), and is ongoing, affecting Rotterdam. No measured effect is published for this event; the effect section explains why.

- Confidence
- medium: The record low and the mid-August stoppage rest on one Bloomberg report (syndicated) and a carrier notice; no WSV publication was retrieved and a second archived news source on the August low point could not be obtained. The October state rests on one federal hydrology report. The start date is approximate and the end is open.
- First reported
- 2026-08-11 (11 August 2026)
- Severity basis: Barge passage at the Rhine's shallowest point, Kaub, was reported effectively blocked in mid-August 2026, a restriction on the main inland route to Rotterdam; no measured port series covers inland barge traffic, so this is an editor judgment.
What happened
Low water on the Rhine fell to the lowest level since records began in 1880 at the Kaub gauge, the river's shallowest point, in August 2026, according to trade reporting on 2026-08-11 (11 August 2026). A shipping broker said the river was effectively impassable at Kaub in both directions, barges that did sail carried much lighter loads, and chemical, steel and energy companies moved freight to rail and road. Forecasters said sustained rain would be needed and the problem could last into October. On 2026-08-12 Maersk told customers that barge transport might become operationally infeasible and published low water surcharges. On 2026-10-01 (1 October 2026) the federal hydrology agency reported that the extreme low water was continuing and that rain expected until mid-October would not be enough to end it, so the end date is open.
Measured effect
No measured effect is published for this event. The affected places are not covered by a daily public series we can use.
The disruption is to inland barge traffic on the Rhine, which is not measured by the port call and chokepoint series in our data. Rotterdam sea port calls are not a measure of barge movements.
Timeline
- Levels at Kaub are reported at the lowest since records began in 1880, with a shipping broker saying barges cannot pass in either direction and companies shifting cargo to rail and road, and forecasters saying the problem could last into October. [s1] [s3] [s4]
- Maersk warns that barge transport on the Rhine may become operationally unfeasible and publishes low water surcharges and a level below which loading is not guaranteed. [s2]
- The federal hydrology agency reports that the extreme low water on the federal waterways is continuing, that rain forecast until mid-October will not be enough to end it, and that Kaub is probably staying in the extreme low water range over the next fortnight. [s5]
Cause
Corrections
- 2026-10-08 (8 October 2026): Added three official sources (s3, s4, s5, Federal Institute of Hydrology low water reports of 2026-08-13, 2026-08-20 and 2026-10-01) and cited s3 and s4 on the record low and the October outlook. No date, figure or entity was changed.. Reason: The record rested on one syndicated news report and a carrier notice. The federal hydrology agency confirms the lowest known water levels on the Rhine and at Kaub in August 2026 and a forecast of no substantial easing before early October.
- 2026-10-15 (15 October 2026): Added a 2026-10-01 timeline entry from the federal hydrology agency (s5), replaced the summary's statement that no source gave the river's state after mid-August with that report's finding, and updated the confidence reason to match. No earlier date, figure or entity was changed.. Reason: The agency's 2026-10-01 low water report shows the extreme low water continuing, so the record's earlier statement that no later source existed was out of date.
