The river Warme Fischa is formed in the region of Wr. Newstadt by the confluence of the rivers Schwarza and Pitten.

The river width is 10-20m with an average water amount of 8m³ per second. Owing to the abundance of food, fish size and stock as well as the number of giant trout and graylings especially are approaching record level.

As the fish mainly live on flee crayfish and larvae of insects, they hardly ever appear at the surface. Thus, optimal fishing success can be achieved if nymphs and other artificial bait (with single hooks only) are offered deep down in the water.

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