The Tormes River is a tributary of the Duero on its left bank, it runs through the Community of Castilla y León, crossing the provinces of Ávila, Salamanca and Zamora. The Tormes rises in the Tormejón meadow, in the Gredos mountain range. It feeds several reservoirs, the Santa Teresa and Villagonzalo reservoirs, the San Fernando reservoir and, close to its mouth in the Duero, the Almendra reservoir, where, sandwiched between rock walls, it forms the so-called arribes del Tormes.
