In 2003 via donau decided to connect the existing old distributaries to Danube within the EU-Life-Projekt.

The goal was to achieve the max. flow rate during the period when the Danube river shows low water level what is to be achieved by max. possibly deep river bed.

The old distributary in question is located in Rührsdorf and it is spread into approx. 3 km long area at the right orographical side of the Danube river.
