A remarkable discovery has been made in the Drava River: an angler in Croatia recently caught a ship sturgeon (Acipenser nudiventris), a species long believed to be extinct in the Danube River Basin. Measuring 176 centimetres and weighing 35 kilograms, the fish was safely released back into the river after being identified by local authorities. The sighting is encouraging as it marks the first confirmed record of the species in many decades.

The ICPDR applauds the recent signing of the"goMURra" Declaration by Austrian Water Minister Norbert Totschnig and Slovenian Minister for Natural Resources Jože Novak. The declaration, signed on 11 November 2025 at the UNESCO 5-Country Biosphere Reserve, marks a significant step forward in transboundary water management and ecological restoration in the Danube River Basin.

Bucharest, Romania – Nine countries along the Danube River have joined forces to protect some of Europe’s most endangered species: the sturgeons. On 9–10 July, thirteen project partners and strategic allies – including national ministries, universities, NGOs and research bodies – gathered in Bucharest to launch “MonStur in the Danube,” a new cross-border effort to monitor and protect these ancient migratory fish.

Sturgeons, the most endangered group of species worldwide, are facing a perilous situation in Europe. These migratory species, which once freely swam from the Black Sea up to Germany, now find their ecological corridors severed by multiple barriers. Human interventions - such as hydropower, sediment extraction, navigation, river channelisation, by-catch and illegal fishing - are exerting severe pressure on habitats and populations, calling for immediate, coordinated actions.

The newly launched Danube Hydrological Information System (DanubeHIS) offers near real-time and validated long-term hydrological and meteorological data for the entire Danube basin. This system is instrumental in enhancing flood risk management and supporting water-related scientific research. Explore this valuable resource and its near real-time data capabilities to better understand and manage the complexities of the Danube basin.

In the wake of what has been declared the nation's 'worst-ever natural disaster,’ more than 70% of Slovenia's territory, predominantly situated in the Danube River Basin, has been severely affected by extreme flooding. The scale of this catastrophe has led to billions of Euros in damages and a tragic loss of lives.
