Rhine at Basel hits record-low discharge since 2020.
On 12 September 2026, the Rhine at Basel recorded exceptionally low discharge, ranking among the lowest values since 2020 and confirming one of the most pronounced low-flow periods in recent record. These low water levels raise transport costs, degrade water quality, stress aquatic life, and restrict cooling, water supply, and groundwater-dependent systems along the river.
