Water levels in the Rhine have fallen to a record low, driving up freight costs and disrupting supplies along Europe’s busiest inland waterway

When the great river that has fed German industry for centuries bares its stony bed, shippers frantically recalculate container loads, and prices for fuel and chemicals start creeping up – the world is reminded that even the most reliable logistics arteries are vulnerable to climate whims. The Rhine, Europe's main water highway, is drying up before our eyes: at the critical Kaub bottleneck, the level has dropped to 25 centimetres, and vessels that once carried 500 containers now struggle to load a hundred.

This is not just a shipping collapse – it is a real blow to the economy that affects petrol, steel and bread prices across the continent. And, as often happens, nature gives no time to prepare: drought struck in midsummer, while promised dredging will not come until 2033.

The Rhine, about 1,230 kilometres long, is Germany's main trade artery, carrying hundreds of millions of tonnes of raw materials such as coal, oil, grain and ore each year. The section near the town of Kaub is the shallowest, and nearly all cargo moving from the port of Rotterdam towards Germany's industrial regions passes through this critical stretch, making the water level there one of the most closely monitored points on the Rhine. "The water level at Kaub serves as a benchmark for ships travelling from the Lower Rhine to places like BASF.

These companies, refineries and the like receive most of their raw materials by water, so they load their ships according to the Kaub gauge," said Bernd Vogt, mayor of Kaub. At this time of year, the water level at the key bottleneck is normally well above two metres, but weeks of drought and persistent heat have brought it down to a historic low of 25 centimetres. Low water levels force ships to reduce cargo loads to avoid running aground, driving up costs and shifting freight to road and rail.

"Because of the low water levels, shipping volumes have dropped significantly. First, cruise ships stopped operating, then larger cargo vessels. Now only relatively small cargo ships are working, and volumes are very low," said Florian Krekel, a representative of Germany's Federal Waterways and Shipping Administration on the Rhine. Freight costs on this stretch of the Rhine have more than doubled since late June, with some operators imposing low water surcharges of more than US$1,100 per container.

"Under normal water levels, a Rhine barge can carry about 500 containers. Currently, that capacity has fallen to 20 percent, meaning just 100 containers. That means 400 containers are sitting somewhere idle, while transporting the remaining 100 is far more expensive," said Fabian Gottlieb, a representative of the Koblenz Chamber of Commerce and Industry. Meanwhile, trucks, trains and additional barges cannot fully compensate for the loss of river freight capacity.

Unlike previous major low water periods, these conditions have hit in midsummer, raising fears that the disruptions could last for weeks or even months. Plans are currently being developed to deepen the Middle Rhine by another 20 centimetres, but completion is not expected before 2033. The extremely low water has already forced some chemical plants, including BASF facilities, to cut production or switch to more expensive transport. According to German economists, each centimetre of falling water adds about 0.1% to inflation in Germany, and the current crisis could prove a serious test for European logistics as a whole.

As CCTV+ reports, the Rhine has once again reminded us that climate change is not a future threat but a present reality, and even Germany's highly developed economy is helpless before a shrinking river, while politicians and engineers argue over projects that remain a decade away.
