Aist River
The Aist is a river system in Upper Austria, a tributary of the Danube. Via its major branches the Feldaist and the Waldaist, and other streams, it drains an area of 647 km2 (250 sq mi).
The Aist rises in Hohensteg (south of Pregarten) and flows through the protected Natura-2000 site Waldaist-Naarn (Fauna-Flora-Habitat Area) on its 15 km (9.3 mi) journey to its confluence with the Danube.
The name "Aist" was derived from a Slavic river designation, recorded in ancient documents such as the Wilhelmine deed. Upper Austria, as well as many other parts of Europe were, at that time inhabited by Slavic peoples. The river appeared for the first time in 853 in a deed as "Agasta". In 983 it is called "Agesta". The prefix "ag" means "drive" or "fast". The name of Dietmar von Aist (1140–1171), a Minnesänger may be related to the Aist.
In the August 2002 flood, the entire Aist area was devastated.
