Record Low Rhine Water Levels Disrupt German Industry and River Traffic

Core Disruption on the Rhine
Since early August 2026, the Rhine’s water depth at the Kaub gauge—a historic chokepoint—has fallen to historic lows, prompting operational challenges for chemicals, steel, utilities, agriculture and tourism. The federal association of German inland shipping (BDB) warned that levels could drop into single-digit centimeters, effectively splitting the waterway. Companies report higher freight costs, reduced cargo volumes and a shift to trucks and rail.
Background: Drought and Climate Context
A prolonged dry spell and heat waves have driven the river’s decline. Scientists cited by German media link the shortage partly to human-induced climate change. The Kaub gauge, measuring Rhine levels since 1856, recorded 16 cm on 12 August 2026, well below the previous record low of 25 cm on 22 October 2018.
Data & Statistics
- Kaub gauge: 16 cm (12 August 2026, Reuters); 14 cm reported later. Forecasted to fall to 9 cm by the following Friday.
- Normal shipments from RWZ’s Worms and Andernach terminals in July–August average >= 50,000 metric tons; this year less than 10 % of that volume has moved.
- Transport cost for scrap steel from Frankfurt to Rotterdam rose from about €10/ton to > €30/ton.
- Vessels can currently carry only one-third of normal loads, tripling the cost per tonne on smaller barges.
- Approximately 150 trucks are required to replace a single barge for construction materials.
Official Statements & Responses
Tim-Oliver Mueller, head of the German Construction Industry Federation, said the situation shows “we need to pay greater attention to waterways as part of our critical transport infrastructure.”
Covestro declared force majeure for polyether polyols at its Dormagen site, citing insufficient transport capacity. Evonik Industries reported “isolated bottlenecks” but kept shipping afloat with low-water vessels. Lanxess confirmed shipments are “severely restricted” and is increasing rail and road use. BASF said it can maintain river shipping by using low-draft vessels. EnBW estimated a low double-digit-million-euro earnings cut.
Transport Minister Steffen Bilger scheduled an emergency meeting with port authorities, transport companies and industry representatives.
On-the-Ground Impacts
Boats at the recreational marina in Koblenz-Ehrenbreitstein were observed sitting on dry land on 10 August 2026. River cruise operators—including AmaWaterways, Emerald Cruises, Scenic and Viking—have announced itinerary changes, ship swaps, coach transfers and hotel stays for passengers on affected sections of the Rhine, Main and Danube.
Conflicting Reports & Gaps
- Gauge readings differ: Reuters cites 16 cm, while Dataportuaria reports 14 cm and a navigable fair-way depth of about 1.27 m at that reading.
- Forecasts vary: Dataportuaria projects a possible drop to 9 cm by Friday; other sources do not specify exact future levels.
- The precise impact on overall German freight volumes remains unquantified; only sector-specific cost increases and capacity reductions have been detailed.
Verbatim Quotes
- “Alarm bells are ringing loudly: the extremely low water levels are increasingly pushing logistics and supply chains to their limits,” — Wolfgang Grosse Entrup, CEO of German chemical industry association VCI
- “Barges positioned on the Upper Rhine are unable to return to the ARA region,” — Riverlake
What’s Next
The German federal waterways authority forecasts further declines, potentially reaching single-digit centimeters within days. Minister Bilger’s emergency meeting will consider temporary suspension of truck-traffic bans in North Rhine-Westphalia, Lower Saxony, Rhineland-Palatinate and Saarland. Industry groups are monitoring shifts to rail and road, while cruise lines continue to adjust itineraries throughout the summer.
