The Rhine carries its name without distinctive accessories only from the [[confluence]] of the [[Vorderrhein|Rein Anteriur/Vorderrhein]] and [[Hinterrhein (river)|Rein Posteriur/Hinterrhein]] next to [[Reichenau, Switzerland|Reichenau]] in [[Tamins]]. Above this point is the extensive [[drainage basin|catchment area]] of the [[headwater]]s of the Rhine. This area belongs almost exclusively to the [[cantons of Switzerland|Swiss canton]] of [[Grisons]] ({{lang|de|Graubünden}}), ranging from [[Saint-Gotthard Massif]] in the west via one valley lying in the [[canton of Ticino]] and [[Province of Sondrio|Sondrio]] ([[Lombardy]], Italy) in the south to the [[Flüela Pass]] in the east. The Rhine is one of four major rivers taking their source in the Gotthard region, along with the [[Ticino (river)|Ticino]] (drainage basin of the [[Po (river)|Po]]), [[Rhône]] and [[Reuss (river)|Reuss]] (Rhine basin). The [[Witenwasserenstock]] is the [[triple divide|triple watershed]] between the Rhine, Rhône and Po.

Traditionally, [[Lake Toma]] near the [[Oberalp Pass]] in the Gotthard region is seen as the source of the Anterior Rhine and the Rhine as a whole. The Posterior Rhine rises in the [[Rheinwald]] below the [[Rheinwaldhorn]].
