For historical reasons, the Ziller—first mentioned in 927 as “Zilare”[2]—for most of its course makes up the border between the Diocese of Innsbruck on the west and the Archdiocese of Salzburg on the east. The Ziller today shows a good presence of brown- and rainbow trout, as well as grayling. It is up to 20 m (66 ft) wide and 2 m (6 ft 7 in) deep, and it has an average discharge of 43.1 m3/s (1,520 cu ft/s).
