In Hohensteg (south of Pregarten ) the Feld- and Waldaist unite to form the Aist. The Aist has a length of 14 kilometers to its confluence with the Danube near Schwertberg . Together with the Waldaist, it has a length of around 72 km.
On its route, the Aist flows through the protected Natura 2000 area Waldaist-Naarn (fauna-flora-habitat area).
etymology
Old documents, such as the Wilhelmine deed of donation, show that the name "Aist" was derived from a Slavic river name. The Mühlviertel, like many other parts of Europe, were then settled by Slavic peoples. The river appears for the first time in a deed of donation as "Agasta" in 853. In 983 he is called "Agesta". The prefix “ag-” meant “drive”, “quickly”.
