The river Rhine in Germany has fallen to new lows, stranding cargo vessels, the country’s inland navigation agency said on Wednesday, as Europe has entered another heatwave. German companies report growing disruption from Rhine water levels that have hit a series of record lows. Most vessels cannot sail either north or south through Kaub so north/south river navigation is effectively stopping at this point, one commodity trader said. The trader said some vessels were returning north to seek work and others were trapped south of Kaub. “However, because of the current low water levels, only about 14,500 tons per day can presently be moved by inland waterways.”
