The forecast flow is around three times below the multiannual July average of 4,750 cubic metres per second. Apele Române said the situation was comparable to 2005, when the Danube also reached a flow rate of 1,650 cubic metres per second. The flow is expected to fall further to around 1,500 cubic metres per second at the entrance to Romania on August 4. The lowest flow recorded at that point was 1,400 cubic metres per second in 1985. The most immediate impact on the energy system has been at Cernavoda, where Nuclearelectrica has been forced to shut down Unit 1 because of the low Danube flow.
