Approximately in the middle of its route, a dam was constructed by Kraftwerke Vorderrhein AG (the local hydropower company), which formed Lai da Curnera. At this point, the Rein da Curnera takes up a left tributary, the Rein da Maighels. The Rein da Curnera flows into the Anterior Rhine near Tschamut in the Tujetsch valley.
