Due to heavy precipitation along the entire northern edge of the Alps, a century flood wave rushed through the Danube valley, causing widespread damage. The Eferdinger Basin, which does not have any flood protection, was hit by a flood such as occurs statistically only every 250 years. The water masses surpassed even the amount from the century flood of 1954. And yet, the high water levels of 1954 were not reached.
In the event of flooding, Danube power plants do not have any means of holding water back. Power plants do help regulate the water level in accordance with officially specified guidelines, the Weir Operating Regulations. The main goal is to protect the dams and the people who live behind them.
Assessments and analyses
In the official flooding report, the Supreme Water Authority (part of the Ministry of Life) confirmed that VERBUND's personnel did everything in their power during the flood to minimise damage as much as possible.
In cooperation with the hydrographic departments of the individual provinces, the Ministry of the Environment presented a detailed analysis of the flooding in June 2013. Besides official data on the event, there is also a comparison with previous catastrophic floods.
