Austria has endured its driest 12 months in 176 years of records, Geosphere Austria said, as drought deepened across the region after rivers from the Rhine to the Elbe disrupted shipping.
Record-low water on the Rhine and other German rivers is now pressing on the construction sector, with vessels forced to cut cargoes and delay deliveries of building materials. The German Construction Industry Association warned of supply bottlenecks if conditions persist, and its director Tim-Oliver Müller said firms may need extra ships or a shift to rail. Transport costs per tonne rise sharply when Rhine ships carry only a fraction of their load, said RWI economist Torsten Schmidt.
Germany's Edersee reservoir is down to roughly 16 percent capacity, partly due to water releases to maintain levels on the Oberweser and Mittelland Canal. Swimming at Waldeck has been suspended and authorities warned against bathing at Rehbach over blue-green algae.
