Europe faces severe water shortage as rivers hit record lows

river low levels European drought water restrictions PFAS contamination cyanobacteria bloom

A prolonged heat wave has driven major European rivers to historic low levels, disrupting transport, energy production and agriculture. The Rhine at Kaub fell to 25 cm on 1 August, the lowest since records began in 1880, while sections of the Danube in Romania and Slovakia also reached record lows, threatening inland shipping and hydro‑electric power.

In Italy, the drought has prompted emergency measures: Veneto ordered a 50 % cut in water withdrawals from the Adige River for irrigation, and the Po basin was declared in a state of high severity, with damages previously estimated at €300 million in 2022 and worsening conditions in 2026. Local authorities have banned swimming in the Piave River and Lake Avigliana after safety concerns and a cyanobacteria bloom, respectively. A newly formed Sicilian Water Rights Committee seeks to pressure utilities over irregular supply and high water losses, while PFAS contamination exceeding the 20 ng/L limit was reported in several northern Italian towns.

These developments illustrate the growing systemic risk of water scarcity across Europe, affecting power plants, logistics, tourism and public health.
