Water levels in the Rhine have fallen to a record low due to the heatwave

Water levels on the Rhine in Germany have fallen to record lows due to prolonged heat and a lack of rainfall, already causing serious restrictions on freight shipping. Vessel operators have been forced to halt navigation on some sections of the river, while ships on other stretches can operate only with significantly reduced loads.

According to Germany’s Waterways and Shipping Administration (WSV), the navigable water depth at the narrow section near Kaub fell to just 15 cm on Tuesday. This is below the previous record low of 25 cm registered in 2018. The actual river depth is approximately 1 meter greater than the official navigable depth measurement.

Freight traffic through Kaub has effectively stopped, while some vessels upstream risk becoming stranded. There are no formal rules specifying the water level at which navigation must be completely suspended, so some empty vessels are still attempting to pass through the affected sections.

Where navigation remains possible, low water levels allow vessels to load only around 20% of their capacity. As a result, cargoes have to be distributed among more vessels, significantly increasing transportation costs. Some freight is already being redirected to trucks, while authorities in several regions have eased weekend restrictions on truck traffic.

Further declines in Rhine water levels could have broader consequences for German and European logistics, as the river is one of the region’s key transport arteries for grain, petroleum products, minerals, coal and other bulk commodities. River transport operators have warned that commercial shipping on some sections could come to a complete halt if water levels continue to fall.
