Rhine River Low Flow Report
Freshly generated from public datasets and ready to read in full.
Rhine at Basel hits record-low October flow since 2020.
On 1 October 2026, the Rhine at Basel-Kleinhüningen recorded an exceptionally low daily discharge of 373 m³/s, among the lowest flows measured since 2020. Such low water levels raise transport costs, degrade water quality, restrict cooling-water use, and stress water supply, groundwater, and ecosystems along the river.
