Europe’s Deepening Drought Threatens Dutch Dikes and Chokes German River Trade

By Orbis Weather Staff | Saturday, August 8, 2026

A severe, months-long drought gripping Europe is straining the continent’s water infrastructure in ways not seen in years, drying the Rhine River to below-record levels, slashing German cargo shipping capacity, and forcing Dutch engineers to keep close watch on flood-defense dikes as the peat beneath them dries out and weakens.

The Rhine, one of Europe’s most vital commercial waterways, dropped below its previous record low at Cologne, Germany — set in October 2018 — on Saturday, July 30, and has remained critically low since. The decline stems from the same punishing heat dome that has baked Central Europe for weeks, driving temperatures above 40°C in Slovakia and Austria and leaving rivers with little rainfall to offset rapid evaporation. The Waal, the Rhine’s main Dutch arm near Nijmegen, and the Lek River have been similarly affected.

The impact on German river trade has been severe. Marcel Beck, who manages western German ports, said a barge that would normally carry 2,000 to 2,500 metric tons of cargo can now haul only 400 to 600 tons, a capacity collapse of roughly 75 to 80 percent. Beck described the situation as placing “an enormous burden on the entire transport chain,” forcing shippers to reorganize logistics around far smaller loads, shift some cargo onto trucks, and absorb higher costs.

In the Netherlands, where roughly a third of the country sits below sea level, the drought poses a different but equally serious risk: the slow weakening of dikes built from peat. Flood defense manager Peter van Duijvendijk explained that as dry conditions persist, peat loses moisture and becomes structurally weaker, opening potential pathways for water to seep through. In response, around 140 volunteers are patrolling roughly 100 kilometers (60 miles) of dikes near Waddinxveen, east of The Hague, probing for cracks and soft spots with metal rods and reporting concerns through a monitoring app. No major structural issues have been found so far this summer, but officials say vigilance will continue into the fall as the drought persists.

The drought’s reach extends well beyond shipping and flood defense. In Nijmegen, houseboats that once floated freely now rest on exposed, sandy riverbeds, and one longtime houseboat owner said summer low-water periods that used to last about a month now stretch to roughly three. Dutch water authorities have banned some farmers from pumping canal water for irrigation over concerns about rising salinity in reclaimed low-lying farmland, threatening fruit harvests during what growers are calling an extremely challenging year. The same heat and dryness have also helped fuel destructive wildfires this summer in France and Spain.

Orbis Weather will continue monitoring drought conditions across Europe’s major river systems as the situation develops. This report was compiled from wire service reporting and interviews with Dutch and German water management officials.
