Sources of the Rhine

Lake Toma in the Swiss canton of Graubünden is generally regarded as the Source of the Rhine. Its outflow is called Rein da Tuma and after a few kilometers, it forms the Vorderrhein/Rein Anteriur. The course of this river is not particularly representative: after about two kilometers, its water is diverted into Curnera reservoir. The water is released at the Tavanase plant and flows into the Rhine at Ilanz. The river begins to be called Rhine in the vicinity of Chur, more specifically, at the confluence of the Vorderrhein and Hinterrhein/Rein Posteriur next to Reichenau in Tamins.
