TheAvers Rhine (Romansh:Ragn da Ferrera,German:Averser Rhein) is atributary of theHinterrhein/Rein Posteriur in theSwiss canton ofGraubünden.
It rises inAvers at the confluence of the Bergalgabach with the slightly smaller Jufer Rhine. The Jufer Rhine rises in, and is named after,Juf, the highest permanent settlement in Europe, near the border withAlbula district. From this confluence, the Avers Rhine descends through a deep gorge, spanned by the 80-metre (260 ft) high Lezi Bridge. When it reaches the valley floor, it meets the slightly smaller Madrish Rhine.
After a few kilometers, it is joined from the left by theReno di Lei, which flows almost entirely onItalian soil. TheLago di Lei reservoir is also on Italian soil, except for the dam which creates it, which was erected on Swiss territory.
The Avers Rhine continues its way through theVal Ferrera valley, which contains two populated places. The upper village isInnerferrera (Romansh:Calantgil), where the river is dammed, forming the Innerferrera reservoir since 1961. BelowAusserferrera (Romansh:Farera), theglacial valley is flanked by steep rocky slopes. The Avers Rhine then flows into the Hinterrhein in theRofla Gorge aboveAndeer.
The road in the Ferrera valley is acul de sac.
