text: This tunnel between the Silvretta and Kops lakes does not exists. On the other hand, there is a tunnel between the Kops and Vermunt lakes, namely the one named "Überleitung Kops-Vermunt mit Zuflüssen " on https://de.wikipedia.org/wiki/Vorarlberger_Illwerke. I assume that the superfluous tunnel is a mislabelling of the real tunnel with the wrong lake (Silvretta instead of Vermunt) as endpoint. christoph.hofer-temmel@illwerkevkw.at
