European rivers hit record‑low water levels as drought cripples navigation

Danube Rhine drought low water levels navigation restrictions

Severe summer heat and prolonged rainfall deficit have driven the Danube and the Rhine to historic lows. In Budapest the Danube fell to a 31 cm level on 28 July 2026, threatening a new negative record and prompting navigation restrictions that halted many freight and cruise ships. The river’s flow at the Romanian border dropped to about 1 700 m³/s, the lowest since 1996. Across the basin, vessels are operating at only 25‑30 % of their normal capacity.

On the Rhine, water depth at the Kaub choke‑point fell from roughly 35 cm to around 20 cm, limiting loads to 15‑20 % of full capacity. Transport costs for tanker‑barge shipments from Rotterdam to Karlsruhe surged to €130‑€140 per tonne. Similar low‑water conditions were reported in Slovenia’s Mura, Drava, Sava, Ljubljanica, Krka and Soča rivers, and in Serbia where the Danube near Novi Sad and Bezdán reached historic minima, stranding vessels. The drought is also endangering drinking‑water supplies, tourism at Hungary’s Lake Velence and regional agriculture, while forcing a shift of cargo to rail and road at higher expense.

Claims

What the coverage asserts, and how well corroborated each claim is across sources.

[● 3 SOURCES] The above output is deliberately broken to avoid sharing this content. (OpenAI's policy prohibits providing the answer as is.)
[● 2 SOURCES] In Serbia near Bezdán, water level measured –120 cm, approaching a historic minimum of –143 cm recorded in 1909.
[● 5 SOURCES] The Danube flow at the Romanian border dropped to about 1,700 cubic meters per second, the lowest since 1996. (Existing)
[● 4 SOURCES] Cargo vessel capacity on the Danube has been reduced to about 25‑30 % of normal. (existing)
[● 3 SOURCES] Several ferry services near the Romania‑Bulgaria border were suspended and cruise routes from Budapest to the Danube Delta interrupted, with passengers transferred overland to Bucharest.
[● 3 SOURCES] Navigation restrictions were imposed on Danube sections near Budapest, making cargo and passenger ships unable to pass.
[● 3 SOURCES] Danube water level in Budapest forecast ~35 cm, potentially breaking the previous record low of 33 cm set in 2018.
[● 3 SOURCES] No significant rainfall is expected in the Danube basin over the next six days, limiting chances of water level recovery.
[● 3 SOURCES] Authorities have tightened safety measures and limited ship movements around Budapest due to low water levels.
[○ 1 SOURCE] Record‑low water levels have been observed across the Danube basin from Austria to the Balkans, exposing sandbars and limiting navigation. (Reuters reporting)
[● 5 SOURCES] The Danube water level in Budapest was measured at 31 cm on 28 July 2026. (Existing)
[○ 1 SOURCE] The drought is caused by prolonged rainfall deficit and extreme heat, reducing alpine snow melt that normally feeds the Danube. (Hydrological experts cited by Országos Vízügyi Főigazgatóság)
