Overview
- Mid‑August 2026 readings at Kaub and Cologne reached new historic lows, with Kaub falling to single‑digit centimetres and the Cologne gauge recording daily record lows, leaving many stretches effectively unnavigable.
- Inland shipping has been sharply limited so freighters must cut loads or stop operating, raising the risk that the Rhine will functionally split into two separate transport sections and disrupt north–south connections to sea ports.
- Chemical firms have already reported concrete effects: Lanxess paused a Krefeld plant and Covestro declared force majeure for a Dormagen site because barge deliveries and cooling water access are constrained.
- States have temporarily lifted or relaxed Sunday truck bans and DB Cargo is preparing to reactivate stored freight wagons, but shortages of drivers, tankers and rail wagons mean road and rail cannot fully replace lost barge capacity.
- Longer‑term fixes such as targeted fairway deepening and so‑called engpassbeseitigung are in planning, yet environmental review, staffing and approvals mean engineering remedies will take years while economists warn of billions in damage and higher consumer prices.
