Austria faces worsening drought and groundwater strain, experts warn

After weeks of dry weather, Austria’s groundwater levels have fallen sharply, prompting bans on pool filling, garden irrigation and car washing in several municipalities. A forest fire north of Graz was finally extinguished after 17 days, and agricultural water use remains high despite the scarcity. Thomas Hein, head of the Institute for Hydrobiology and Water Management at BOKU, warned that groundwater recharge is slow and that climate change could cut Austria’s groundwater reserves by up to 23 % by 2050 while water demand may rise 15 % due to population growth.

In Carinthia’s Spittal district, water‑utility official Martin Rohr noted that recent precipitation deficits of 40‑50 % have lowered soil and aquifer stores, but the existing supply infrastructure can meet average demand. He cautioned that localized shortages could appear during peak tourism, unregulated pool filling or intensive lawn watering. Snowmelt this spring was reduced, worsening the deficit, although a short spell of rain is forecast. Authorities have appealed for water‑saving measures and called for a transparent water‑use register to better track withdrawals across industry, agriculture, golf courses and ski resorts.
