The Rein da Curnera (in German: Curnerarhein) is a right tributary of the Anterior Rhine and one of the main tributaries of the Rhine (see Sources of the Rhine). It is fed from multiple sources and glaciers at the southern end of the valley. The river is about 8km (05miles) long and flows north through the Val Curnera. 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.
