Freshly generated from public datasets and ready to read in full.
Rhine at Basel hits record low flow since 2020.
On 15 August 2026, the Rhine at Basel-Kleinhüningen recorded exceptionally low discharge, with August 2026 having the lowest minimum average monthly flow since 2020. These low water levels raise transport costs, degrade water quality, and restrict cooling, irrigation, and groundwater-dependent systems along the river.
