This area comprises the Danube above and below the power station including the left- and right-hand banks of the old river arms to the extent of 334 ha of water surface.

On account of its extended back water regions whose maintenance is extremely expensive, this area represents a special section of the Austrian part of the Danube with a big variety of fish. Every fisherman must be aware of the fact that it is not a breeding water where he is fishing, the fish must be worked for hard. However, it is Wallsee offering a great chance to catch the fish of your life, as the big fish is confronted here with ideal biological conditions. Every year many a giant pike, pikeperch, wels or carp can be caught here at Wallsee as well as all kinds of salmonids and all other types of Danube fish in addition. Being persistent, skilful and flexible, you may be lucky to catch the fish you have been dreaming of, here in this area.

It is compulsory to have an official fishing-or guest license for Lower Austria and Upper Austria.
