The three river sections of Wang, Steinakirchen and Wieselburg comprise the river Kleine Erlauf from Hörhag (marked about 1 km above Randegg by respective boards), downstream until it flows into the river Große Erlauf.

Each of these sections is about 10 km long, especially suitable for fly fishing. The river Kleine Erlauf is a medium-size river at the foothills of the Alps, approx. 8m (upper reaches) to 14m (lower reaches) wide.

The fisherman is confronted with quickly flowing sections and quiet regions respectively. The entire river length is characterized by special meandering. The measures necessary in connection with the river regulation from the point of view of water supply and distribution were carried out in a way as to preserve the natural path of the river as far as possible by using big stones for the reinforcement of the river bank.

The natural fish stock includes brown-and rainbow trout and graylings.

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