Record-low Rhine water threatens German freight and economic recovery

Weeks of drought have left the Rhine at historically low levels, with the Kaub stretch measuring about 16 cm, according to the Federal Waterways and Shipping Administration. This depth is well under the 40 cm limit that allows standard commercial barges to pass, prompting carriers to slash cargoes to roughly 20 % of usual loads across the Middle Rhine and other shallow points such as Cologne and Duisburg-Ruhrort. Jens Schwanen of the BDB inland-shipping association warned that the river could become impassable at Kaub before week’s end, effectively dividing the waterway.

The disruption comes as Germany’s economy struggles with weak growth and high energy costs; inland waterways move about 5 % of national freight, and a 30-day low-water spell historically cuts industrial output by about 1 %. The German Economic Institute now predicts a 0.4 % GDP contraction, wiping out the projected 0.5 % gain, while sector analysts estimate losses of €1-2 billion in the third quarter. Transport Minister Steffen Bilger has pledged to relax Sunday truck limits, cut red tape for heavy loads, halt unnecessary roadworks, and improve coordination with DB Cargo to mitigate supply-chain strain. Climate scientists note that such extreme low-water events are becoming more frequent as warming reduces Alpine snow and glacier melt that traditionally sustain the Rhine.
